1.7.2.3.9 State LEDs
The LEDs are located at the front of the 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 29 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.

The voltage at digital outputs DC0..DC7 and DO0..DO7 has exceeded the
process supply voltage UP3 (see 'Connections'
tions" on page 660). A diagnosis message appears for the whole module.
This message appears if the output of a channel DC0..DC7 or DO0..DO7
should be switched on while an external voltage is connected. In this case
the 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. Subsequently, a new start-up will be executed. This diagnosis mes-
sage appears for each channel.
