120200 Image preparation suppressed
Definitions: The control is so heavily loaded by the processing of a subroutine, that it cannot keep all the display
values up-to-date.
Reaction: Alarm display.
Remedy: The alarm disappears automatically as soon as the overload situation has been eliminated.
If this alarm occurrs often, the start-up engineer will have to take appropriate measures (e.g. reduce
IPO clock pulse rate).
Program Internal
Continuation:
120201 Communication failure
Definitions: The operator panel is connected with the NC and PLC via a serial bus.
This alarm occurs when the communication to these components is interrupted.
In connection with this alarm, all display values connected with the NC/PLC become invalid.
Such faults are normal while the controls are ramping up (e.g. after resetting).
Reaction: Alarm display.
Remedy: The alarm disappears automatically as soon as the fault situation has ended.
If this alarm is continuously present, a wide variety of faults may be the cause. (e.g. wire breakage,
NC/PLC not ramped up,
faulty address/data transfer rate configuration of one of the bus nodes, etc.).
