3.    Introduction

The purpose of this standard is to provide a uniform protocol for communicating with any generating set control equipment. It allows all telemetry information relevant to a generating set to be read from the control equipment, regardless of manufacturer or specification, and allows basic operations such as starting and stopping the engine, transferring the load etc. to be performed remotely.

 

This standard does not define how to program the control equipment, or transfer manufacturer specific information such as configurations to or from the equipment.

 

This standard does not define the physical link, but is compatible with RS232, RS423, RS485, modem links or any similar system.

 

This standard uses the Modbus protocol, complete details of which can be found on the Modbus-IDA web site http://www.modbus-ida.org

 

4.    General Definitions and Requirements

 

Notes

1.     A single piece of generating set control equipment is referred to as a ‘control unit’.

2.     A control unit is always a slave device as defined in the Modbus protocol.

3.     A PC, building management system or similar system is referred to as a ‘master device’ as defined in the Modbus protocol.

4.     A hub is a device which connects a master device to one or more control units, to a master it appears as a slave and to a control unit it appears as a master.

5.     A control unit connected to a hub is referred to as a satellite device of the hub.

6.     The term ‘slave device’ refers either to a control unit or to a hub when it is viewed from a masters point of view.

7.     The transmission mode used shall be RTU not ASCII.

8.     The byte format over an RS485 link shall be 1 start bit, 8 data bits, no parity bit and 2 stop bits as defined by the Modbus protocol.

9.     The byte format over an RS232 link to a modem or direct to a PC shall be 1 start bit, 8 data bits, no parity bit and 1 stop bit which is the de-facto standard for modems.

10.   The baud rate used will be one of those listed in Page 1 - Communications Configuration.

11.   Bus time-outs must be detected by the master, as defined in the Modbus protocol.

12.   For details of the Unicode character representation refer to the Unicode standard version 2.0 published by the Unicode Consortium.

13.   Unicode strings may contain the control code 0x000A which shall be interpreted as “move to the beginning of the next line down”.

14.   Any software that reads a Unicode string may either use the control code 0x000A to split the string into separate lines or may replace it with 0x0020 if it is desired to display the string on a single line, it must not be ignored as this may lead to the concatenation of words.

15.   In this standard the term ‘ASCII character’ refers to an 8 bit character following the sub-set of Unicode from 0 to 255, it does not refer to any other published standard of character representation to avoid the ambiguities in such standards.

16.   The form 0x12AB refers to a hexadecimal number, all other numbers are in decimal.

17.   This document describes GenComm version 1, future upgrades of this standard will increase this version number by 1 and must be fully backwards compatible with all previous versions.

18.   Any software written to interface with a GenComm version n slave device will be able to interface with a GenComm version n+1, n+2 etc. slave device without modification, and will be able to perform any operation defined in version n, but will not, of course, be able to perform functions added in later versions.

19.   Any software written to interface with a GenComm version n slave devices will recognise a GenComm version n-1 slave device (from the ‘Communications Status Information’ page) and perform all operations defined in version n-1 on that slave device, it will not attempt to perform any operations added in later versions of GenComm on that slave device.

 

 

 

5.    Hubs and Protocol Conversions

A hub may be designed to connect to satellite devices of one of 3 types, ones that recognise the GenComm protocol directly, ones that recognise another Modbus based protocol, or ones that use an entirely unrelated protocol. In the second and third cases the hub must provide protocol conversion which is not defined in this standard.

 

Notes

1.   A hub recognises queries from a master device for a range of slave addresses, e.g. a hub with its own slave address set to 20 and 8 satellite sockets will recognise slave addresses 20 to 28. Address 20 corresponds to the hub itself, 21 to its first satellite socket, 22 to its second satellite socket, etc. The hub will respond to all these slave addresses even if there is no satellite connected to a particular satellite socket.

2.   A hub will accept queries to its own slave address where appropriate, for example a hub may have some auxiliary digital inputs and outputs.

3.   A valid password must be entered into a hub (at its own slave address) before any of its satellite devices or its own registers can be accessed in any way, thus the hub provides security for the entire installation via a single password.

4.   A hub designed for GenComm satellites recognises a query from a master that has a slave address corresponding to one of its satellites, checks that the password privilege level is adequate for the specified operation, passes this query on to the satellite, and then returns any response back to the master.

5.   A hub designed for other Modbus satellites recognises a query from a master that has a slave address corresponding to one of its satellites, checks that the password privilege level is adequate for the specified operation, converts the protocol as necessary, passes the query on to the satellite, and then returns any response with appropriate conversion. Note that such a hub may not be able to provide security for the satellite as it may not fully understand the satellites protocol, in which case it simply passes the message on regardless of password levels and delegates security to the satellite.

6.   A hub designed for non-Modbus satellites must provide complete protocol conversion and must emulate the GenComm registers so that it appears to the master as a GenComm satellite. All security will also appear to work in exactly the same way as for a GenComm satellite.

7.   For a description of password privilege levels refer to the Password status register in Page 1 - Communications configuration and status.

8.   A hub designed for GenComm satellites will set the slave addresses of all satellites when it initialises, or of a particular satellite when it does not respond. For example a hub with slave address 20 will set its satellites to slave addresses 21, 22 etc. This is achieved without knowing the satellites current slave address by sending broadcast messages (slave address 0) to the satellite to set its slave address. This ensures that the hub will not have to convert the slave addresses in queries from a master or in responses from a satellite. This process can only function if the satellites passwords are completely disabled, which is normally the case for a satellite.

9.   A hub designed for Modbus satellites may not be able to set the satellites slave address in this way, the addresses may have to be set manually on each satellite or the hub may have to convert the addresses in each query and response.

10. Although this standard talks about 'satellite sockets' the connection between a hub and satellite may be of any form, a single socket for each satellite, an RS485 bus with the hub as the master, or some other method.

 

6.    Multiple Masters

GenComm is based on Modbus which is a protocol that is only intended for a simple single master network, therefore it does not support multiple masters accessing a slave simultaneously.

 

If a slave device has more than one interface that can act as a master, it must only serve one master at once. Whenever it changes masters it must completely re-initialise the status of the port, in particular it must clear the password status to 0 (Invalid) and the extended exception information to 0 (No error), thus ensuring that there can be no interaction between masters of any kind. Any master that makes a query while its port is not being served must either be answered by exception 6 (Slave device busy) whatever the query was, or not answered at all.

 

The mechanism used by a slave device to decide which master to serve is not defined in this standard, it may be a physical switch, a configuration option or an automatic switch using some mechanism to decide which master to serve. An example of an automatic switch would be a slave device that had an RS485 port to a building management system and an RS232 port to a modem, in this case it might be decided that whenever a modem link is established the RS485 port will be disabled and when the modem link was broken the RS485 port was re-enabled. In such a case it would have to be accepted that the RS485 port would be unavailable whenever the modem link was in use.

 

GenComm does not support multiple communications configurations for multiple master ports.

 

 

7.    Exception Responses

Any function may return an exception response if it does not complete successfully, as define in the Modbus protocol.

 

Notes

1.     The Modbus Protocol Reference Guide defines the meanings of exception codes 1 to 8 and the Open Modbus/TCP Specification defines error codes 10 and 11, but unfortunately these meanings are ambiguous, so cannot convey accurate information about the error. This standard, therefore, defines an extended exception code and exception address which can be read from the slave device at registers 0 and 1 respectively.

2.     A slave device will only return exception code 1, 2 or 6 if a function fails, in the case of exceptions 1 and 2 the extended exception code and address should then be read to find more information about the exception.

3.     The extended exception code will be set to the result of the last message, which implies that a successful read of this register will clear it, this occurs after the read has been performed.

4.     The extended exception address will be set to the address of the register that caused the exception, or to 0 if inappropriate. This allows precise identification of the cause when reading or writing multiple registers.

5.     The extended exception code and address must both be read by a single message, reading them individually would meaningless as they would each refer to different messages.

6.     Extended exception codes 1-255 can be generated by any slave device but codes above 256 can only be generated by a hub.

7.     Exception code 6 (Slave device busy) will be returned whenever a slave device is completely unable to reply to a query because it is occupied, in this case the extended exception codes cannot necessarily be read. An example of this is when a slave device is serving a master of a higher priority than the one that made the query.

8.     In the case of a hub the extended exception registers contain the result of a query to the hub, they are not changed by a query to a satellite. The corresponding registers in the satellite must be read to obtain the result of such a query.

Manufacturer specific error

An error occurred in a manufacturer specific operation either using register pages 128-255 or functions other than 3 and 16. The meaning of these exception codes is manufacturer specific, any software not knowing the meaning for a particular slave must print the message ‘Manufacturer specific error n’ where n is the exception code.

 

 

 

8.    Modbus Functions Used

This standard only uses Modbus functions 3 and 16 as recommended in the Open Modbus/TCP Specification draft 2.

 

Notes:

1.     Any other functions may be implemented if required, for example for configuration of the slave device, but are not defined in this standard.

2.     Any device which requires other functions to be implemented in order to perform a task which can be performed by function 3 or 16 is deemed to be non-compliant with this standard.

9.    Description of Each Function

9.1    Function 3 - Read Multiple Registers

Reads one or more 16 bit registers from the slave device.

 

Notes:

1.     The limit of 125 registers is to comply with the Modbus specification which requires that a message must not exceed 256 bytes including all fields.

2.     Any request for a register that is defined in this standard must return a normal response, if the register is not implemented by a particular product it must return the unimplemented value from the table below to indicate this fact, it must not return an exception.

3.     A request for a register that is defined in this standard as contain some unimplemented bits must return a normal response, the unimplemented bits will contain the unimplemented value from the table below.

4.     A request for a register that is defined in this standard as unimplemented will return the unimplemented value from the table below.

5.     A request for a register that is defined as reserved in this standard will return extended exception code 12 (Reserved register).

6.     A read from a multi-register value such as a 32 bit value or a string must be performed by a single message, not by multiple ones. This avoids the possibility of a value being partly current and partly old data.

7.     The instrumentation values can return the sentinel values described in the table below to indicate a value that is over or under the measurable range, that a transducer is faulty, that the data is bad for some other reason or that the transducer is actually a digital type.

8.     The sentinel value ‘high digital input’ means that the instrumentation value is high (high oil pressure, high temp, etc), similarly 'Low digital input' means the instrumentation value is low. They do not refer to voltage levels on the inputs.

9.2    Function 16 - Write Multiple Registers

Writes one or more 16 bit registers to the slave device.

 

Notes:

1.     The limit of 123 registers is to comply with the Modbus specification which requires that a message must not exceed 256 bytes including all fields.

2.     A write to a register that is defined in this standard but not implemented on this slave device will return extended exception 4 (Register not implemented) and have no other affect.

3.     A write to a register that is defined in this standard as unimplemented will return extended exception 4 (Register not implemented) and have no other affect.

4.     A write to a register that is defined in this standard as containing some unimplemented bits will only affect the implemented bits, the state of the unimplemented bits is irrelevant.

5.     An attempt to write to a register that is defined as reserved in this standard will return extended exception code 12 (Reserved register) and have no other affect.

6.     A write to a multi-register value such as a 32 bit value, a password or a string must be performed by a single message, not by multiple ones. This avoids the possibility of a value being partly current and partly old data.

10.    Language Codes

 

Notes:

1.   Language codes follow the Windows definition, the primary language code is stored in the least significant 10 bits and the sub-language code is stored in the most significant 6 bits of the 16 bit language code.

2.   Microsoft add to this list periodically but have reserved sections of the list for custom languages and sub-languages. Primary language codes 0x200-0x3FF can be used for additional languages and sub-language codes 0x20-0x3F can be used for additional dialects of a primary languages but these should only be used where none of the defined codes is appropriate.

11.    Modbus Registers Defined

Notes:

1.     The register array is divided into 256 pages each containing up to 256 registers, the actual register address is obtained from the formula: register_address=page_number*256+register_offset.

2.     All unused parts of pages 0-127 are defined as reserved for expansion of this standard, any attempt to access them will result in an exception response with extended exception code 12 (Reserved register).

3.     Pages 128-255 are available for manufacturer specific applications such as configuration of the control equipment, these are not defined by this standard.

4.     Any device which requires registers in pages 128-255 to be implemented in order to perform a task which can be performed by registers defined in this standard is deemed to be non-compliant with this standard.

5.     This document always refers to register addresses which start at 0 as defined in the Modbus protocol. Register numbers, which start at 1, are not used in this document in order to avoid confusion.

6.     The additional instrumentation pages are to be defined.

7.     S.M. means state machine.

8.     A letter S in the bits/sign column indicates a signed value using two’s compliment arithmetic, all others are unsigned.

9.     A double number in the bits/sign column indicates a bit within a register of a specific size e.g. 16/16 is the most significant bit and 1/16 is the least significant bit of a 16 bit register.

10.   Bits within registers are numbered from 1 not 0 to avoid the confusion that would be caused if the sixteenth bit of a 16 bit register were labelled  15/16.

11.   For an integer type register the register contents should be multiplied by the scaling factor to obtain the actual value.

12.   For a flag type register (1 bit) the minimum value column indicates the meaning if the flag is 0, the maximum column indicates the meaning if the flag is 1.

13.   For an integer type register the minimum and maximum value columns indicate the minimum and maximum values after multiplying by the scaling factor.

14.   Any software that reads an integer type register must be able to process and display correctly over the full range specified in the minimum and maximum value columns.

15.   32 bit values are stored with the most significant bits in the register with the lowest address.

16.   Where two ASCII characters are stored in a single register the first character is in the most significant bits.

17.   The first register of a 32 bit number is always aligned at an even address for the benefit of some 32 bit CPUs.

2.     Registers 0 and 1 must both be read with a single message for them to be meaningful since they are set after each message.

3.     Registers 2 and 3 contain copies of the telemetry alarm flags of all satellites so that the satellite that caused a dial out can be ascertained without reading the telemetry alarm flags from all the satellites individually. This register is not latched, clearing the telemetry alarm flag of a satellite will clear the corresponding bit in these registers when the hub updates them. The hub will not assume that sending a system control message to a satellite to clear its telemetry alarm flag will necessarily succeed, instead it builds registers 2 and 3 by reading the state of all the satellites telemetry alarm flags periodically.

4.     Registers 4 and 5 contain communication error flags for all the satellites. A flag is set if, and only if, the corresponding satellite socket is fitted, it is enabled by the corresponding ‘satellite socket enable flag’ in page 1 - Communications Configuration, and the hub is not able to communicate successfully with the satellite for any reason.

5.     If any communication error flag changes from 0 to 1 the hub’s telemetry alarm flag will be set and so cause a dial out if a modem is connected with dial out enabled, the satellites telemetry alarm flag in register 2 or 3 will not be set since this would contradict its non-latching operation as described in note 3 above. A system control function must be used to clear the hub’s telemetry alarm flag before the connection is broken or the dial out will be repeated.

6.     The meaning of the password status is shown in the table below.

7.     If the password status is 0 (no valid password) then it is not possible to read the extended exception information..

8.     If the number of satellite sockets is 1-32 the unit is a hub, otherwise it is not. A hub with 8 sockets, for example, returns a value of 8 regardless of what is actually plugged into the sockets or what the satellites state is, and will always respond to 8 consecutive slave addresses starting with its own slave address +1.

9.     The GenComm version number allows a master to recognise the version of GenComm supported by a slave device and act accordingly. 72xx/73xx modules are identified by the GenComm version of 2, 53xx/55xx etc modules have a GenComm version of 1.

10.   Registers 10 and 11 contain flags that indicate the available baud rates, bit 1 corresponds to baud rate code 0 etc. If a bit is set the corresponding Baud rate is available.

11.   The list of language codes that are available on a particular slave device can be obtained by first reading the number of languages available and then reading that number of registers from the beginning of the list of language codes available. Reading any further registers from the list will return the unimplemented register value 0xFFFF. The order of the language codes in the list has no significance and no assumptions should be made.

Password status

Status

Meaning

0

No valid password has been entered, no operations can be performed on the slave device except writing a password using function 16 (write multiple registers). In the case of a hub no queries will be passed to its satellites at all.

1

A valid read password has been entered, all readable registers (including manufacturer specific ones above page 127) can be read on the slave device using function 3 (read  multiple registers). All write operations using function 16 (write multiple registers) and all non-GenComm functions (those other than 3 and 16) are blocked. In the case of a hub only  queries using function 3 (read  multiple registers) will be passed to its satellites.

2

A valid control password has been entered, as level 1 except that all registers in page 16 (control registers) can be written to in the slave device using function 16 (write multiple registers). In the case of a hub only queries using function 3 (read  multiple registers), and function 16 (write multiple registers) to registers in page 16, will be passed to its satellites.

3

A valid configure password has been entered, as level 1 except that all writeable registers (including manufacturer specific ones above page 127) can be written to in the slave device, and all non-GenComm functions (those other than 3 and 16) can be used for configuration of the slave device. In the case of a hub all queries will be passed to a satellite. The configuration of units using non-GenComm functions is not defined in this standard.

 

 

 

11.3    Page 1 - Communications Configuration

 

Notes:

1.   These are a mixture of read/write and write only registers (except on 72xx/73xx where registers 0-9 are read-only, not read/write).

2.   The current slave address is fixed at 10 in the case of an RS232 link to a modem, or direct to a PC, since there is no point in changing a slave address on a 1 to 1 link. Address 10 was chosen so that that satellite 1 has slave address 1 etc. Register 0 specifies the current slave address in all other cases.

3.   The site identity code is user definable and is used to identify a site.

4.   The device identity code is user definable and is used to identify a device within a site.

5.   The meaning of the baud rate is shown in the table below, a slave device may not necessarily support all baud rates, writing an unsupported value will return extended exception 7 (Illegal value written to register) and will not change the Baud rate. Some systems may not allow the Baud rate to be changed at all, it may be set by switches or from a user interface for example. The baud rates available on a particular slave can be obtained by reading a register in the communications status page.

6.   The current language applies only to strings read by telemetry, it is quite separate from the language selected for any user interface on the unit. The meaning of the code is defined in the language codes section.

7.   The satellite socket enable flags allow each satellite socket to be enabled or disabled, a socket that is fitted but not in use must be disabled or the hub will think that the lack of response indicates a problem and set the corresponding satellite error flag and telemetry alarm flag. The enable flag for a socket that is not fitted will always be 0, any attempt to set it will be ignored.

8.   The master inactivity time-out is used to detect the loss of communication from the master, if a query is not received for this period the slave device assumes the link to the master has been lost. The link is assumed to have been established as soon as a query arrives from the master.

9.   The password time-out is used to disable the password automatically, if a valid password is not written for this period the password status will be set to 0 (invalid) or the highest disabled password level.

 

Notes on passwords:

1.   Passwords are intended to control access to control equipment via telemetry, they are not necessarily the same as passwords used to access the same equipment from a user interface. Such user interfaces are not defined in this standard in any way.

2.   Passwords are 4 digit numbers similar to ‘PIN numbers’ which are widely accepted and easier to enter via a limited user interface than alphanumeric strings.

3.   One of the 3 valid passwords is written into register 32 and its ones-compliment written into register 33 with a single function 16 (write multiple registers) to set the current password status.

4.   The password status in the communications status information page indicates which level of access has been granted, when the password times out the status becomes 0 (invalid) or the highest disabled password level.

5.   Entering a password that does not match one of the 3 valid passwords will cause the password status to be set to 0 (invalid) or the highest disabled password level and return extended exception 7 (Illegal value written to register)

6.   The password status can be cleared to 0 (invalid) or the highest disabled password level either by writing a password that is known to be invalid or by writing any value to register 32 without writing to register 33.

7.   If an invalid password is entered 3 times the slave device will then reject any further attempt to enter a password for a 1 minute lockout period, returning extended exception 8 (Inappropriate circumstances) at the third attempt (so it is immediately clear what has happened) and whenever a further attempt is made to enter a password during the lockout period. The password lockout period will double after every 3 unsuccessful attempts to enter a password, up to a maximum of 64 minutes, thus minimising the risk of a deliberate attack being able to find a valid password. When a valid password is entered the count of invalid entries will be reset to 0. The count of invalid entries and the current lockout timer will not be reset by loss of the communication link as it would be possible for an attacker to drop the link to reset them and then immediately re-establish the link.

8.   When the link to a master is lost (a phone line is dropped or the master inactivity timer expires for example) the password status is set to 0 (invalid) or the highest disabled password level.

9.   The ‘read only’ password is changed by writing the new value to register 34 and its ones-compliment to register 35 with a single function 16 (write multiple registers), any other operation will fail to change the password and return extended  exception 7 (Illegal value written to register). The ‘control’ and ‘configure’ passwords are changed in the same way using the appropriate registers. The current ‘configure’ password must have been entered before any passwords can be changed.

10. If a password is changed to 0000 then that password level will be disabled, the password status will then default to the highest level that is disabled rather than 0 when an invalid password is entered, the password times out or the link to the master is lost. Even if one or more of the passwords has been changed to 0000, any attempt to write a password of 0000 to register 32 and 33 will be treated exactly as if an invalid password was entered.

11. A hub is intended to provide security for all its satellites using its own passwords, thus avoiding the complexity of managing passwords in every satellite separately, to facilitate this each satellite must have all its passwords disabled by setting them to 0000. If this is not done it is not possible to enter any password into a satellite unless the configure password is entered into the hub first, this is necessary to simplify the message filtering mechanism needed in the hub but is not a problem if the hub is used to provide security to the satellites as intended.

Notes

1.     These are read/write registers (except on 72xx/73xx where they are read-only & only updated by writing a configuration file).

2.     Modem control strings can contain any ASCII characters and are padded with spaces (ASCII 0x20), NULL terminators are not used.

3.     Each string is automatically suffixed with <CR><LF> so these should not be included in the string, strings are not automatically prefixed with ‘AT’ so these must be included when required.

4.     A string may contain a meta character consisting of 3 tildes (~~~) which indicates that a pause of 1 second should be introduced before the rest of the string is sent to the modem. This meta character may be repeated if longer delays are required. The tildes will not be sent to the modem.

5.     If a dialling string contains only spaces (ASCII 0x20) it will not be used in the dialling sequence.

6.     The meaning of the modem’s mode is described in the table below.

7.     The modem dial back string can be used by a master to call the slave device, it is never used by the slave device..

8.     The SMS enable flag enables the transmission of SMS messages over a GSM modem, the method of transmission, circumstances that trigger a transmission and contents of the messages are not defined in this standard.

9.     The SMS message centre number and recipient number are in the same format as the other modem control strings and are only used when the SMS system is activated by the SMS enable flag, their use is not defined in this standard.

11.5    Page 3 - Generating Set Status Information

Notes:

1.     These are read only registers.

2.     A unique manufacturer code is assigned to each manufacturer.

3.     The meaning of the model number is manufacturer specific, e.g. two manufacturers may have a model 100.

4.     The manufacturer code and model number must be used together to identify a particular product unambiguously.

5.     The meaning of the control mode is shown in the table below.

6.     The shutdown flag on a control unit indicates that one or more of the alarm codes has been set to ‘shutdown alarm’, it will clear automatically when no alarm codes are set to shutdown alarm. A system control function is used to clear shutdown alarms. In some situations it may not be possible to set one of the alarm codes to indicate the type of shutdown alarm because the type is not known, in this case only the shutdown flag will be set and the master should consider it an undefined shutdown alarm.

7.     The shutdown alarm flag on a hub indicate that state of the hub itself, not the state of any satellite. The state of a satellite must be read from the satellite itself.

8.     The electrical trip and warning alarm flags operate in the same way as the shutdown alarm flag but for the corresponding alarm codes.

9.     The telemetry alarm flag on a control unit is set when the control unit decides that a dial-out is required, the logic behind this is product specific. It can only be cleared by a system control function.

10.   The telemetry alarm flag on a hub is only set if the hub itself has a problem, and can only be cleared by a system control function. It is edge triggered i.e. once it is cleared it will not be set unless the internal error is cleared and then happens again. An example of a situation that will set this flag is if the hub loses communication with a satellite.

11.   The satellite telemetry alarm flag is the OR of all the satellite telemetry alarm flags in the ‘telemetry status and configuration’ page and indicates that one or more satellites requires servicing.

12.   Whenever the telemetry alarm flag (or one of the satellite telemetry alarm flags in the case of a hub) is set it will cause continual dial outs if a modem is fitted and dial out is enabled.

13.   The meaning of the state machine status is described in the table below.

14.   The string checksum is the sum of every character in every fixed string in the slave device, it is used to detect the substitution of a slave device that differs only in its strings and thus check the validity of any copies of these strings held by a master. This number must not change during the normal operation of the slave device. The exact method of calculating the checksum must not be assumed and it must not be compared with a checksum generated my a master, it must only be compared with a previously read checksum to determine change.

Notes on control modes:

1.   ‘Stop mode’ means stop the engine (generator) and in the case of ‘automatic mains failure units’ transfer the load to the mains if possible.

2.   ‘Auto mode’ means automatically start the engine (generator) in the event of a remote start signal or a mains-failure, and in the case of ‘automatic mains failure units’ transfer the load to the generator when available. When the remote start signal is removed or the mains returns, stop the engine (generator) and in the case of ‘automatic mains failure units’ transfer the load back to the mains.

3.   ‘Manual mode’ means start the engine (generator) With some control units it will also be necessary to press the start button before such a manual start is initiated. In the case of ‘automatic mains failure units’ do not transfer the load to the generator unless the mains fails.

4.   ‘Test on load mode’ means start the engine (generator) With some control units it will also be necessary to press the start button before such a manual start is initiated. Transfer the load to the generator when it is available, regardless of the mains condition. This mode is only provided on automatic mains failure units.

5.   ‘Auto with manual restore mode’ means the same as 2 above but when the remote start signal is removed or the mains returns, the engine (generator) will not stop and the load will not be transferred back to the mains. This mode is only provided on automatic mains failure units.

6.   ‘User configuration mode’ means that the unit is being configured from its user interface and is not available for normal operation, there is no method of entering or leaving this mode by telemetry, it must be done from the user interface.

7.   Any control unit that does not have a control mode will return the unimplemented value.

Notes on state machine status:

1.     A state machine that is implemented (status 0 or 1) has a fixed name string in page 27 that can be used in a status display, the name strings for unimplemented state machines will contain 32 spaces (Unicode 0x0020).

2.     A state machine that is implemented has a state string in page 28 which may be used in a status display. The contents of this string will change when the state machine changes state and this is indicated by the status changing from 0 to 1, when the state string is read the status will change back from 1 to 0. This means that the string only has to be read when there is a change in state, thus minimising the volume of traffic.

Notes:

1.     These are read only registers.

2.     Each auxiliary sender has a register describing it's type as shown in the table below.

3.     Auxiliary sender values are always signed regardless of the category.

4.     An unused auxiliary sender should return the appropriate unimplemented sentinel in both the category and value registers, however, some products may return a 0 value in the category register to indicate that it is unimplemented.

5.     Registers 12-15 have been added to 55xx from version 9 upwards

11.10    Page 8 - Alarm Conditions

Notes:

1.     These are read only registers.

2.     Each alarm can be in one of 15 conditions as shown in the table below.

3.     Registers 1-32 contain the status of named, internally generated, alarms and indications. These may be extended by future versions of GenComm and any software that reads them must be able to cope with such extensions. This is possible because register 0 specifies the number of pre-defined internal alarm conditions that are implemented on a slave device, the software should read and process the specified number. The software does not need to know the definitions of any new alarms since it can read the alarms strings and display them as specified by the alarm condition. All unimplemented pre-defined alarms return the unimplemented value 15, not an exception.

4.     Registers 129-160 contain the status of unnamed digital inputs. Register 128 specifies the number of unnamed digital inputs and any software that reads them must be able to cope with all 128 in the same way as for the pre-defined alarms. All unimplemented digital inputs up to 128 will return the unimplemented value 15, not an exception.

5.     Each alarm has 2 strings in pages 32-95 which can be displayed on a PC for example, the alarm code specifies which string it is appropriate to display.

6.     The contents of alarm strings will never change while the slave device is operating so a copy can be held by the master to minimise traffic.

Notes on alarm codes

1.   An alarm that is fitted but disabled by the configuration of the slave device returns code 0.

2.   An alarm that is not implemented on a particular control unit returns code 15.

3.   An indication that does not require a message to be displayed when inactive returns either code 8 or 10.

4.   An indication that does require a message to be displayed when inactive returns either code 9 or 10.

5.   The inactive strings are only required for indications, in all other cases they will contain 32 spaces.

Notes:

1.     These are read only registers.

2.     Register 0 gives the version as major/minor, with the major version in the upper 8 bits, the minor version in the lower 8 bits.

Notes

1.     These are read only registers.

2.     These registers represent the state of the actual inputs to the control unit before the application of any time delays or other processing and are intended for diagnostic purposes only.

3.     The number of named digital inputs may be increased in future versions of GenComm. Manufacturers may not add their own to the list of named inputs as there are no corresponding strings to identify them. Any inputs that are required but not named must be included in the list of unnamed digital inputs.

4.     The meaning of the named digital input codes is shown in the table below.

5.     Register 16 indicates the number of unnamed digital inputs that are supported, any software that displays these must cope with any number up to 128. Each is represented by only one bit as there is no need to indicate that it is unimplemented.

6.     Unimplemented inputs (including totally unimplemented registers) return 3, not an exception.

11.13    Page 13 - Diagnostic - Digital Outputs

Notes:

1.     Generally these are read only registers to avoid conflict between the slave devices chosen output state and commands from a master. However, in some cases a slave device may accept write commands to these registers, e.g. a hub may have digital outputs which are not controlled by the hub itself but from a master device. A slave device may only accept write commands to these registers if this does not cause a conflict with internally generated controls of the outputs.

2.     These registers represent the state of the actual digital outputs of the control unit after any internal processing and are primarily intended for diagnostic purposes only (but see note 1).

3.     The number of named outputs may be increased in future versions of GenComm. Manufacturers may not add their own to the list of named outputs as there are no corresponding strings to identify them. Any outputs that are required but not named must be included in the list of unnamed digital outputs.

4.     The meaning of the named digital output codes is shown in the table below.

5.     Register 16 indicates the number of unnamed digital outputs that are supported, any software that displays these must cope with any number up to 128. Each is represented by only one bit as there is no need to indicate that it is unimplemented.

6.     Unimplemented outputs (including totally unimplemented registers) return 3, not an exception.

11.14    Page 14 - Diagnostic - LEDs

Notes:

1.     Generally these are read only registers to avoid conflict between the slave devices chosen LED state and commands from a master. However, in some cases a slave device may accept write commands to these registers, e.g. a hub may have LEDs which are not controlled by the hub itself but from a master device. A slave device may only accept write commands to these registers if this does not cause a conflict with internally generated controls of the outputs.

2.     These registers represent the state of the actual LEDs on the control unit after any internal processing and are primarily intended for diagnostic purposes only (but see note 1).

3.     Register 0 indicates the number of LEDs that are supported, any software that displays these must cope with any number up to 128.

4.     Unimplemented LEDs (including totally unimplemented registers) return 15, not an exception.

11.15    Page 16 - Control Registers

Notes:

1.     These are a mixture of read only and write only registers.

2.     Registers 0 to 7 contain flags that indicate the available system control functions. If a bit is set the corresponding function code is available.

3.     One of the system control keys from the table below must be written into register 8 and its ones-compliment written into register 9 with a single function 16 (write multiple registers) to perform the specified system control function.

4.     Writing any other value or using a function that is not available will return extended exception code 7 (Illegal value written to register) and have no affect.

5.     Function codes 0 to 31 perform exactly the same function as pressing the equivalent button on the control unit.

6.     Function 34 ‘reset alarms’ is not the same as function 7. The former resets any alarm condition codes that can be reset. The latter simulates a button which may or may not exist on the control unit, if it does not exist it will have no affect. If all alarm condition codes are able to be reset the shutdown, electrical trip and warning alarm active flags (as appropriate) in page 3 will consequently reset.

7.     Function 34 does not under any circumstances reset the telemetry alarm flag in page 3, function 35 must be used for this.

8.     Locking the user controls stops the buttons corresponding to function codes 0-31 from operating and stops any attempt to configure the unit from the user controls. It does not stop the user from viewing status information and instrumentation values.

9.     Function 38 resets the Page 7 values ‘Time to next maintenance’ and ‘Time of next maintenance since 1/1/70’. The reset values are manufacturer specific, if it is desired to set one of these two items to a specific value then they can be directly written to in Page 7.

10.   Function 10 resets only those alarms associated with the detection of mains failure while running in parallel with the mains, i.e. G59 alarms and ROCOF and vector shift.

11.16    Page 17 - J1939 active diagnostic trouble codes in decoded format

Notes:

1.     These are read only registers.

2.     Some Engine Control Units (ECUs) do not comply with J1939 with respect to trouble codes, the trouble code type must be read to determine the interpretation of the codes.

3.     For an ECU that is fully compliant with J1939 this page contains the status as indicated by the last DM1 message, refer to J1939-73 section 5.7.1.

4.     For an ECU that is not fully compliant with J1939 this page contains trouble codes as read by the mechanism appropriate to the ECU.

5.     The meaning of the lamp status codes is shown in the table below.

6.     For details of the Suspect Parameter Number (SPN) refer to J1939-04 Appendix C.

7.     For details of the Failure Mode Indicator (FMI) refer to J1939-73 Appendix A.

8.     For details of the Occurrence Count (OC) refer to J1939-73 section 5.7.1, a value of 127 indicates that no OC is available.

9.     For details of the Fault Code Number, Status of Fault Code and Number of Occurrences refer to the Scania document 'Fault codes EMS S6'.

10.   For details of the Fault Code Number refer to the MTU document “Part 3 Maintenance and repair E531 711 / 01 E”

Notes:

1.   These are read only registers.

2.   Each string consists of 32 Unicode characters with the first character at the lowest register address, NULL terminators are not used.

3.   The manufacturer string and model string must not be used to identify a particular product as they may change from one unit to the next, e.g. a manufacturer may change its name in some way.

4.   The remaining strings can be used in a status display.

5.   The contents of these strings will never change while the slave device is operating so a copy can be held by the master to minimise traffic.

4.   A complete string must be read with a single query to avoid the possibility of reading parts from different strings, any attempt to read part of a string will return extended exception 13 (Block violation).

5.   Up to 3 complete consecutive strings can be read with a single query, limited only by the packet size limitations of Modbus.

6.   Reading a string causes the corresponding state machine status code in the ‘generating set status information’ page to change to 0.

7.   A string can be read regardless of the state machine status code.

8.   Reading the string for a unimplemented state machine will return 32 spaces (Unicode 0x0020).

11.23    Pages 32 to 95 - Alarm Strings

Notes:

1.   These are read only registers.

2.   Each string consists of 32 Unicode characters with the first character at the lowest register address, NULL terminators are not used.

3.   There are 2 strings corresponding to each alarm, refer to the alarm conditions page for details of their use.

4.   The contents of these strings will never change while the slave device is operating so a copy can be held by the master to minimise traffic.

5.   Reading the string for an unimplemented alarm will return 32 spaces (Unicode 0x0020).

6.   The inactive string for an alarm may not be used, in which case it will return 32 spaces (Unicode 0x0020).
