6.3 Behavior of the digital outputs
Display
The channel status LEDs are directly affected by the signal level at the socket.
Response to error detection
All channels that are in pause mode on "PE_MODE_PROCEED" report their diagnostic status as
in productive mode.
The following applies for all channels which switch to a different pause mode:
•
During the "pause", error detection of "Short circuit" is not possible:
– Alarms for errors already pending before the "pause" are retained.
– After the "pause" is over, the error status is updated and incoming/outgoing errors are
reported correspondingly.
