Communication interrupted for crosswise data comparison
PLC, error detected by %1
%1 = supplementary information about the detecting monitoring
channel
In the monitoring channel (NCK or PLC) specified in the alarm text, the
delay stage (1 s) for communication monitoring has been exceeded.
The other monitoring channel did not send new data within this time.
Alarm display
A timer of 5 s is started -- after it has expired
-- The external NCK--SPL outputs are deleted (cleared)
-- The PLC goes to stop.
Do not start the SPL anymore. Check the system components (PLC
must have the correct version of FB15 and have DB18).
Switch--off – switch--on the control
Checksum error NCK- -SPL, %1, %2, %3
%1 = supplementary information about the type of error
%2 = supplementary information about the reference size
%3 = supplementary information about the current size
The checksum error in the NCK SPL. The file
/_N_CST_DIR/_N_SAFE_SPF was subsequently modified.
The safe programmable logic (SPL) in the NCK may be corrupted.
Parameter %1 provides further information about the type of change:
%1 = FILE_LENGTH: The file length has changed.
%1 = FILE_CONTENT: The file contents have changed.
%1 = FILE_PROTECT: The access rights to the file are restricted and
have been violated as the SPL commissioning phase has been exited.
%2 specifies the variable calculated as the reference (file length,
checksum over file contents),
%3 specifies the current size calculated cyclically.
Alarm display
Check the file and when the file was last changed. Reload the original
file and start the monitoring system again with a power on.
Switch--off – switch--on the control
%1 SPL protection not activated
%1 = name of the component for which the protection is not activated
(NCK or PLC)
The protective mechanisms for the SPL have not been activated. The
commissioning phase of the SPL has not yet been completed. For an
error in the crosswise data comparison between NCK and PLC, a stop
response (Stop D or E) is not initiated.
