Meaning
Module cannot send an interrupt because a
•
previous interrupt has not been processed
Possible cause: Too many hardware inter-
•
rupts in too short a time
Firmware update in progress
•
or update has been canceled.
The module reads no
process values in this state.

Possible causes:
•
– Short circuit
– Overload
Error at the digital outputs

H
Possible causes:
•
– Short circuit
– Overload
Error at supply voltage L+
•
H
Possible causes:
•
– Low voltage
– Wiring of L+ supply voltage defective
Time profile of signals A and B of the in-
•
H
cremental encoder does not meet certain
specifications
Possible causes:
•
– Signal frequency too high
– Encoder faulty
– Process wiring faulty
Remedy
Change interrupt processing in the
•
CPU and re-assign technology module
parameters correspondingly
Check frequency of interrupts from the
•
process
Wait for firmware update
•
If firmware update aborts:
•
– Check minimum firmware version
required
– Check supply voltage
– Repeat firmware update
Replace technology module
Run firmware update
