State LEDs
The LEDs are located at the front of module. There are 2 different groups:
● The 5 system LEDs (PWR, STA1 ETH, STA2 ETH, S-ERR and I/O-Bus) show the operation
state 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.

This message appears, if externally voltages at one or more terminals
DO0...DO7 cause that other digital outputs are supplied through that voltage
Ä Chapter 1.7.6.2.3 "Electrical Connection" on page 1008. All outputs of the
apply digital output groups will be turned off for 5 seconds. The diagnosis
message appears for the whole output group.
The voltage on digital outputs DO0...DO7 has overrun the process supply
Ä Chapter 1.7.6.2.3 "Electrical Connection" on page 1008.
voltage UP3
Diagnosis message appears for the whole module.
This message appears, if the output of a channel DO0...DO7 should be
switched on while an externally voltage is connected. In this case the start up
is disabled, as long as the externally voltage is connected. Otherwise this
could produce reverse voltage from this output to other digital outputs. This
diagnosis message appears per channel.
Short circuit: After a detected short circuit, the output is deactivated for
100 ms. Then a new start up will be executed. This diagnosis message
appears per channel.
In case of an I/O module doesn't support hot swapping, do not perform any
hot-swap operations (also not on any other terminal units (slots)) as modules
may be damaged or I/O bus communication may be disturbed.
Diagnosis for hot swap available as of version index F0.
