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
4
)
In case of module errors, with channel "31 = Module itself" is output.
