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.

)
With "Device" the following allocation applies:
31 = module itself, 1..10 = expansion 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

)
In case of module errors, with channel "31 = Module itself" is output.
State LEDs
During the power ON procedure, the module initializes automatically. All LEDs (except the
channel LEDs) are ON during this time.
