ABB AC500 PLC - 1.7.1.2.9 State LEDs

1
)
In AC500, the following interface identifier applies:
"-" = Diagnosis via bus-specific function blocks; 0 ... 4 or 10 = position of the
communication module;14 = I/O bus; 31 = module itself
The identifier is not contained in the CI541-DP diagnosis block.

)
With "Device" the following allocation applies: 31 = module itself; 1..10 = decen-
tralized communication interface module
3
)
With "Module" the following allocation applies:
31 = module itself
Channel error: module type (1 = AI, 2 = DO, 3 = AO)
4
)
This message appears if external voltages at one or more terminals DO0..DO7
cause other digital outputs to be fed by that voltage (voltage feedback, descrip-
tion in Electrical Connection Ä Chapter 1.7.1.2.3 “Electrical Connection”
on page 704). All outputs of the digital output groups will be turned off for 5 sec-
onds. The diagnosis message appears for the whole output group.

)
The voltage on digital outputs DO0..DO7 has overrun the process supply voltage
UP3 (description in Electrical Connection Ä Chapter 1.7.1.2.3 “Electrical Con-
nection” on page 704). Diagnosis message appears for the whole module.
6
)
This message appears if the output of a channel DO0..DO7 is to be switched on
while an external voltage is connected. In this case, start-up is disabled while the
external voltage is connected. Otherwise, this could produce reverse voltage
flowing from this output to other digital outputs. This diagnosis message appears
for each channel.

)
Short circuit: After a short circuit has been detected, the output is deactivated for
100ms seconds. Subsequently, a new start-up will be executed. This diagnosis
message appears for each channel.
1.7.1.2.9 State LEDs
The state LEDs are located at the front of module. There are 2 different groups:
● The 5 system LEDs (PWR, CN-RUN, CN-ERR, S-ERR and I/O bus) show the operation
states of the module and display possible errors.
● The 27 process LEDs (UP, UP3, inputs, outputs, CH-ERR1 to CH-ERR3) show the process
supply voltage and the states of the inputs and outputs and display possible errors.
