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 (1 = AI); COM1/COM2:
1...10 = expansion 1..10

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