2 - 8 esd Protocol for CAN Modules Rev. 3.2
Commands and Parameters 3. Description of the Individual Commands and Parameters 3.1 Configuration Reply The transmission is called by transmitting a 'request configuration' command. The identifier on which the module should transmit the information on the CAN is reported to it by byte 5 and 6. Contrary to the other commands only parameters are called with this command. Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Function Command Sub command Not used Module no. Parameter 1 Parameter 2 Always Selected Value $00 $00...$05 write module no. $00 $01...$FF Table 3.1.1: Bytes of the command 'request configuration' Explanation of the Bytes Transmitted to the Module: CTxId $0000...$07FF Command... The command 'request configuration' requests the transmission of the actual parameters of the module. Sub command... The sub command determines the configuration bytes which should reply: Sub command Reply of the parameters $00 Module type $01 Active switch $02 ASCII Id $03 Software rev. $04 local module time $05 serial number Table 3.1.2: Selection of the configuration reply by sub command Parameter 1 and 2... With these parameters it is reported to the module to which CAN Id. it should transmit the requested reply. The module does only transmit once on this identifier. The identifier is not stored on the module. If another transmission is desired another INIT Id with the corresponding parameters has to be transmitted to the module. esd Protocol for CAN Modules Rev. 3.2 3 - 1
