Introduction
$he purpose of this standard is to provide a uniform protocol for communicating with any generating set control e>uipment. !t allows all telemetry information relevant to a generating set to %e read from the control e>uipment2 regardless of manufacturer or specification2 and allows %asic operations such as starting and stopping the engine2 transferring the load etc. to %e performed remotely. $his standard does not define how to program the control e>uipment2 or transfer manufacturer specific information such as configurations to or from the e>uipment. $his standard does not define the physical lin(2 %ut is compati%le with :S&+&2 :S'&+2 :S')52 modem lin(s or any similar system. $his standard uses the /od%us protocol2 complete details of which can %e found on the /od%us#!DA we% site httpwww.mod%us# ida.org
)
#eneral Definitions and -e&uirements
Notes 1. A single piece of generating set control e>uipment is referred to as a 0control unit. &. A control unit is always a slave device as defined in the /od%us protocol. +. A PC2 %uilding management system or similar system is referred to as a 0master device as defined in the /od%us protocol. '. A hu% is a device which connects a master device to one or more control units2 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 hu% is referred to as a satellite device of the hu%. 6. $he term 0slave device refers either to a control unit or to a hu% when it is viewed from a masters point of view. . $he transmission mode used shall %e :$< not ASC!!. ). $he %yte format over an :S')5 lin( shall %e 1 start %it2 ) data %its2 no parity %it and & stop %its as defined %y the /od%us protocol.

Hubs and "rotocol $on.ersions
A hu% may %e designed to connect to satellite devices of one of + types2 ones that recognise the GenComm protocol directly2 ones that recognise another /od%us %ased protocol2 or ones that use an entirely unrelated protocol. !n the second and third cases the hu% must provide protocol conversion which is not defined in this standard. Notes 1. A hu% recognises >ueries from a master device for a range of slave addresses2 e.g. a hu% with its own slave address set to &, and ) satellite soc(ets will recognise slave addresses &, to &). Address &, corresponds to the h u% itself2 &1 to its first satellite soc(et2 && to its second satellite soc(et2 etc. $he hu% will respond to all these slave addresses even if there is no satellite connected to a particular satellite soc(et. &. A hu% will accept >ueries to its own slave address where appropriate2 for e-ample a hu% may have some au-iliary digital inputs and outputs. +. A valid password must %e entered into a hu% 8at its own slave address9 %efore any of its satellite devices or its own registers can %e accessed in any way2 thus the hu% provides security for the entire instal lation via a single password. '. A hu% designed for GenComm satellites recognises a >uery from a master that has a slave address corresponding to one of its satellites2 chec(s that the password privilege level is ade>uate for the specified operation2 passes this >uery on to the satellite2 and then returns any response %ac( to the master. 5. A hu% designed for other /od%us satellites recognises a >uery from a master that has a slave address corresponding to one of its satellites2 chec(s that the password privilege level is ade>uate for the specified operation2 converts the protocol as necessary2 passes the >uery on to the satellite2 and then returns any response with appropriate conversion. ote that such a hu% may not %e a%le to provide security for the satellite as it may not fully understand the satellites p rotocol2 in which case it simply passes the message on regardless of password levels and delegates security to the satellite. 6. A hu% designed for non#/od%us 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 wor( in e-actly the same way as for a GenComm satellite. . 3or a description of password privilege levels refer to the Password status register in Page 1 # Communications configuration and status. ). A hu% designed for GenComm satellites will set the slave addresses of all satellites when it initialises2 or of a particular satellite when it does not respond. 3or e-ample a hu% with slave address &, will set its satellites to slave addresses &12 && etc. $his is achieved without (nowing the satellites current slave address %y sending %roadcast messages 8slave address ,9 to the satellite to set its slave address. $his ensures that the hu% will not have to convert the slave addresses in >ueries from a master or in responses from a satellite. $his process can only function if the satellites passwords are completely disa%led2 which is normally the case for a satellite. ". A hu% designed for /od%us satellites may not %e a%le to set the satellites slave address in this way2 the addresses may have to %e set manually on each satellite or the hu% may have to convert the addresses in each >uery and response. 1,. Although this standard tal(s a%out ;satellite soc(ets; the connection %etween a hu% and satellite may %e of any form2 a single soc(et for each satellite2 an :S')5 %us with the hu% as the master2 or some other method.

*ultiple *asters
GenComm is %ased on /od%us which is a protocol that is only intended for a simple single master networ(2 therefore it does not support multiple masters accessing a slave simultaneously. !f a slave device has more than one interface that can act as a master2 it must only serve one master at once. ?henever it changes masters it must completely re#initialise the status of the port2 in particular it must clear the password status to , 8!nvalid9 and the e-tended e-ception information to , 8o error92 thus ensuring that there can %e no interaction %etween masters of any (ind. Any master that ma(es a >uery while its port is not %eing served must either %e answered %y e-ception 6 8Slave device %usy9 whatever the >uery was2 or not answered at all. $he mechanism used %y a slave device to decide which master to serve is not defined in this standard2 it may %e a physical switch2 a configuration option or an automatic switch using some mechanism to decide which master to serve. An e-ample of an automatic switch would %e a slave device that had an :S')5 port to a %uilding management system and an :S&+& port to a modem2 in this case it might %e decided that whenever a modem lin( is esta%lished the :S')5 port will %e disa%led and when the modem lin( was %ro(en the :S')5 port was re#ena%led. !n such a case it would have to %e accepted that the :S')5 port would %e unavaila%le whenever the modem lin( was in use. GenComm does not support multiple communications configurations for multiple master ports.

E7ception -esponses
Any function may return an e-ception response if it does not complete successfully2 as define in the /od%us protocol. Notes 1. $he /od%us Protocol :eference Guide defines the meanings of e-ception codes 1 to ) and the =pen /od%us$CP Specification defines error codes 1, and 112 %ut unfortunately these meanings are am%iguous2 so cannot convey accurate information a%out the error. $his standard2 therefore2 defines an e-tended e-ception code and e-ception address which can %e read from the slave device at registers , and 1 respectively. &. A slave device will only return e-ception code 12 & or 6 if a function fails2 in the case of e-ceptions 1 and & the e-tended e-ception code and address should then %e read to find more information a%out the e-ception. +. $he e-tended e-ception code will %e set to the result of the last message2 which implies that a successful read of this register will clear it2 this occurs after the read has %een performed. '. $he e-tended e-ception address will %e set to the address of the register that caused the e-ception2 or to , if inappropriate. $his allows precise identification of the cause when reading or writing multiple registers. 5. $he e-tended e-ception code and address must %oth %e read %y a single message2 reading them individually would meaningless as they would each refer to different messages. 6. E-tended e-ception codes 1#&55 can %e generated %y any slave device %ut codes a%ove &56 can only %e generated %y a hu%. . E-ception code 6 8Slave device %usy9 will %e returned whenever a slave device is completely una%le to reply to a >uery %ecause it is occupied2 in this case the e-tended e-ception codes cannot necessarily %e read. An e-ample of this is when a slave device is serving a master of a higher priority than the one that made the >uery. ). !n the case of a hu% the e-tended e-ception registers contain the result of a >uery to the hu%2 they are not changed %y a >uery to a satellite. $he corresponding registers in the satellite must %e read to o%tain the result of such a >uery.
