Info

Commands and Parameters Byte 4: iomode... The byte 'iomode' contains, broken down into 6 bits, information about the operating mode of the addressed module. A '1' of the respective bit signalizes the operating mode possible for this module: 3 - 4 Bit Function Example: CMIO 0 Output 1 1 Input 1 2 Digital 1 3 Analog 1 4 Controller 0 5 Serial 0 6 Reserved 1*) 0 7 Reserved 1*) 0 1*) These bits are read as '0'. Sub command $01 --< active switch Table 3.1.5: Bits in parameter 'iomode' Example: At a CMIO module the value $0F would be replied for 'iomode'. Byte1, Byte2... See sub command $00. Byte 3: switch... The byte 'switch' replies the number adjusted on the coding switches. If the module no. filed in the EEPROM has got the value $00 or if the EEPROM data are not OK, the actual module no. by which the module is addressed during the initialisation corresponds to this coding switch number. esd Protocol for CAN Modules Rev. 3.2
Sub command $02 --< ASCII Id Byte 1... See sub command $00. Byte 2 - Byte 6 a, b, c, d, e... These bytes describe the module type in ASCII code. Commands and Parameters Byte 7, Byte 8: mod no. ASCII... These two bytes describe the module name and the active module number in ASCII code. The following table gives an example for the display of these bytes in ASCII code. It is a CMIO module with the module no. $99. Byte 2 3 4 5 6 7 8 Parameter a b c d e Module no. H Module no. L ASCII Id CMIO Sub command $03 --< software revision M I O 4 2 9 9 Table 3.1.6: Example for an ASCII Id (CMIO module with module no. $99) Byte 1... See sub command $00. Byte 2 - Byte 5 'V', level, '.', rev.... In ASCII code these bytes describe the revision number of the firmware of the CAN core used on the module. Byte 2 and byte 4 are permanently allocated with the ASCII symbols 'V'($56) or '.'($2E). In byte 3 and byte 5 the actual revision number is described. Byte 6 contains a letter which stands for the revision of the module-specific firmware. In byte 7 is returned, which protocol is implemented (esd CAN protocol or CMS protocol). An 'e' means, that the esd CAN protocol is implemented and a 'c' means, that the CMS protocol is implemented. Byte 8 returns the actual revision number of the used protocol (e.g. of the esd CAN protocol). esd Protocol for CAN Modules Rev. 3.2 3 - 5
