Module 9194 Alarm when operating time exceeded
You define a marker that is set when a certain threshold is exceeded. The
marker is set every minute after the threshold is passed. The marker can be
delayed by max. 59 s the first time it is set. All values greater than 2 147 483
648 (approx. 69 years) must be transferred as negative numbers.
If you enter the value zero as the alarm threshold, the function is deactivated.
Call only in a submit job or spawn job.

Error recognition:
Module 9195 System time
The TNC operates with UNIX system time. The system time contains the
number of seconds accumulated since 0:00 hours on January 1, 1970.
When the TNC is shipped it is calibrated for Universal Time (also known as
Greenwich Mean Time).
In MP7235, enter the time difference between the local time and Universal
Time so that the time of the program management matches the local time.
With Module 9195 you can read the current value of the system time. The
value read with Module 9195 is independent of MP7235 and always refers to
Universal Time.
