Assertion failed in %1: %2
%1 = String (path with program name)
%2 = String (line number)
This alarm is purely a development alarm and will not appear in a delivered software ver-
sion. For an OEM customer, this alarm could indicate that an alarm has occurred in the
system softwaren. Handling of the 'assertion' allows error conditions leading to this alarm
to be defined in the system software during the development phase. After the develop-
ment phase, this alarm output is no longer active.
- NC not ready.
- The NC switches to follow-up mode.
- Channel not ready.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
- Alarm reaction delay is canceled.
Check the cause of the error in the specified software component at the specified line
number.
Clear alarm with the RESET key in all channels. Restart part program.
PLC sign-of-life monitoring
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.
- 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.
Please inform the authorized personnel/service department. Check monitoring time frame
in NCK-MD 10100 PLC_CYCLIC_TIMEOUT (reference value: 100 ms).
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).
Switch control OFF - ON.
PLC has not started up
The PLC must give a sign of life within a period of time defined in MD 10120
PLC_RUNNINGUP_TIMEOUT (Default setting: 1 sec.).
- 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.
