ABB AC500 PLC - 1.6.2.1.8 State LEDs

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 (2 = DO); COM1/COM2: 1...10 =
expansion 1...10
4
)
In case of module errors, with channel "31 = Module itself" is output.
1.6.2.1.8 State LEDs
During the power-on procedure, the module initializes automatically. All LEDs (except the LEDs
for the signal states) are on during the initialization.
