Remarks:

¹)	In AC500, the following interface identifier applies: 14 = I/O bus, 11 = COM1 (e.g. CS31 bus), 12 = COM2. The FBP 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)
³)	With “Module” the following allocation applies depending on the master: Module error: I/O bus or FBP: 31 = module itself; COM1/COM2: 1..10 = expansion 1..10 channel error: I/O bus or FBP = module type (1 = AI); COM1/COM2: 1..10 = expansion 1..10
⁴)	In case of module errors, with channel “31 = Module itself” is output.
