• The number of alarm texts is currently limited to 5000. This limit has been exceeded by
the alarm text configuration.
All other alarm texts:
• Alarm texts are stored in files. One of these files could not be accessed properly.
- Alarm display.
• Expand the alarm list (Enter maximum number in the file mbdde.ini in the section
[Alarms]). Then perform a cold restart for the operator panel.
•
• Reduce the number of alarm texts. Then perform a cold restart for the operator panel.
•
• Make sure that the MMC memory on the hard disk is available after booting, or re-install
the MMC software. When entering your own alarm texts, check whether the path and
file name are entered correctly in mbdde.ini.
Internal
Image preparation suppressed
The control is so heavily loaded by the processing of a subroutine, that it cannot keep all
the display values up-to-date.
- Alarm display.
The alarm disappears automatically as soon as the overload situation has been elimi-
nated.
If this alarm occurs often, the start-up engineer will have to take appropriate measures
(e.g. reduce IPO clock pulse rate).
Internal
Communication failure
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).
- Alarm display.
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.).
Internal
Waiting for a connection to the NC
The operator panel is connected with the NC and PLC via a serial bus.
This alarm occurs if the MMC is started for the first time and the NC/PLC ramp-up is not
yet finished or the communication to these components is faulty.
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).
- Alarm display.
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.).
