)
In AC500 the following interface identifier applies:
14 = I/O bus, 11 = COM1 (e.g. CS31 bus), 12 = COM2.
The PNIO diagnosis block does not contain this identifier.

)
With "Device" the following allocation applies:
31 = module itself, 1...10 = expansion module 1...10, ADR = hardware
address (e. g. of the DC551-CS31)
3
)
With "Module" the following allocation applies depending on the master:
Module error: I/O bus or PNIO: 31 = module itself; COM1/COM2: 1...10 =
expansion 1...10
Channel error: I/O bus or PNIO = module type (3 = AO); COM1/COM2:
1...10 = expansion 1...10

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