State LEDs
The LEDs are located at the front of module. There are 2 different groups:
●
The 5 system LEDs (PWR, STA1-DP, STA2-DP, 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 (voltage feedback, see description in section Electrical Connec-
Ä Chapter 1.7.5.1.3 "Electrical Connection" on page 944). All out-
tion
puts 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 voltage UP3 (see description in section Electrical Connection
Ä Chapter 1.7.5.1.3 "Electrical Connection" on page 944). 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. Oth-
erwise 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
100ms. 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.
