Remarks:

1)

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.

2)

With "Device" the following allocation applies:

31 = module itself, 1 ... 10 = decentralized communication interface 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 (2 = DO); COM1/COM2: 1 ... 10 = expansion 1 ... 10

4)

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