    error: Incorrect entry in MP2200.0 & non-volatile PLC markers/words...

    Hello.
    Machine HEIDENHAIN iTNC 530
    The non-volatile PLC markers / words and the control data in the RAM were erased, after which the error "Incorrect entry in MP2200.0" appeared on the screen. We cannot reset the error to continue working.
    Unfortunately, the file PLC: \ PLCMEM.A was not saved.
    Tell me how you can fix this problem?
    Thank you in advance.

    Hi,
    Which machine is this? Do you have the backups/CDs which came with the machine? If yes you can restore the backup with TNCRemoNT and the machine would run again.

    If you know the parameter as to what it should be, you could press the circular arrows key when this error comes up and enter into the parameter table the normal way thereafter.

    Best regards

    Hii

    Erasing the RAM in 530 will not erase the plc.

    Your side check the connections / Earlier this same alarm message before RAM reset?
