Continuation:
2000 PLC sign-of-life monitoring
Definitions: The PLC must give a sign of life within a defined period of time (machine data 10100
PLC_CYCLIC_TIMEOUT). If this does not occur, the alarm is triggered.
The sign of life is a counter reading on the internal NC/PLC interface which the PLC causes to count
up with the 10 ms time alarm. The NCK also tests cyclically whether the counter reading has changed.
Reaction: NC not ready.
Local alarm reaction.
Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Check monitoring time frame in NCK-MD
10100 PLC_CYCLIC_TIMEOUT (reference value: 100ms).
Establish the cause of the error in the PLC and eliminate it (analysis of the ISTACK. If monitoring has
responded with a loop in the user program rather than with a PLC Stop, there is no ISTACK entry).
Program Switch control OFF - ON.
Continuation:
