Significance
Applies when the I/O controller does not supply
valid output data for the module or the group of
modules
•
the set strategy on the side of the station
distributor applies (I/O device).
•
so that all outputs are immediately reset
•
that all outputs maintain the last valid value
•
so that all outputs switch to their configured
default value
The following occurs per diagnostics data sets and
diagnostics alarm with external faults
•
not transferred to the I/O Controller
•
transferred to the I/O Controller
The process data will be transferred
•
using the format settings of the I/O device.
•
Little Endian Format

Big Endian Format
If the switching of substitute values has been
selected as a fault strategy, the substitute output
data of the individual output channels can be
determined here.
