Dear Shubi, our technical documentation on web says the following: 120202 Waiting for a connection to the NC/PLC Definitions: The operator panel is connected to 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). 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.). I would recommend you to contact the Siemens Hotline in that case: https://support.industry.siemens.com/my/ww/en/requests#createRequest you can see this post with the name of APC-Tech or Sir Nulizhang posts you can fimd gd solution |
