Input/output modules
There are one or two LEDs (status displays) next
to the relevant connections on the input/output
modules. The colours of these LEDs are:
•
green (status display of digital inputs)
•
yellow (status display of digital outputs)
•
red (error display of digital outputs)
The current signal at each input/output is shown
by means of the yellow and green LEDs. The red
LEDs of the outputs indicate short circuit or
overload of the relevant output.
