Significance
With external faults, channel diagnostics and the
respective alarms are
•
not transferred to the I/O Controller
•
transferred to the I/O controller
In case the I/O controller does not supply valid
output data for the module or the group of modules
then
•
the set strategy on the side of the station
distributor applies (I/O device).
•
all outputs are immediately reset
•
all outputs maintain the last valid value
•
all outputs switch to their configured substitute
value
When configuring the substitute value behavior on
the side of the I/O module, these values are
transmitted to the binary signal channel with invalid
output states of the I/O controller.
