)
In AC500, the following interface identifier applies:
14 = I/O bus, 11 = COM1 (e.g. CS31 bus), 12 = COM2.
2
)
With "Device" the following allocation applies:
31 = module itself,
1...10 = communication interface module 1...10,
ADR = hardware address (e.g. of the DC551)
3
)
With "Module" the following allocation applies depending on the master:
Module error: I/O bus: 31 = Module itself; COM1/COM2: 1...10 = expansion
1...10
Channel error: I/O bus = module type (1 = AI, 3 = AO, 4 = DC); COM1/COM2:
1...10 = expansion 1...10

)
In case of module errors, with channel "31 = module itself" is output.
