Remarks:

¹)	AC500 uses the following interface identification: 14 = I/O Bus, 11 = COM1 (e.g., CS31 Bus), 12 = COM2 FBP diagnosis blocks do not contain this identifier.
²)	The assignment for “Device” is as follows: 31 = Module, 1..10 = Expansion 1..10
³)	The assignment for “Module” is as follows: 31 = Module or module type (1 = AI, 3 = AO, 4 = DC)
⁴)	In case of module errors, “31 = Module” is reported for the channel.
⁵)	In the AC500 CPU firmware version, errors reported to the AC500 CPU by the DC505-FBP cannot be directly made visible on the display or in the PLC browser.
⁶)	Communication Module errors: 1 = UDP DataExchange, 2 = UDP no AC31 Header, 3 = Online Protocol, 4 = Netconfig, 5 = SNTP, 6 = MODBUS
