Thanks, Pratts23. Hello, Please do the following procedure: In the case of all system messages that relate to ”internal errors”, please follow the procedure outlined below. Switch off the OP, set the PLC to STOP mode and then restart both units. During startup, set the OP to download mode, download the configuration again and then restart the OP and PLC again. If the fault recurs, please contact your nearest Siemens representative. When doing so, please quote the number of the error that has occurred and any variables referred to in the message. Or Send the unit for repair quoting the error message. Above data are extracted from OP7 Manual, See Page B-2 Attachment Op717_e.pdf (260 Downloads)

I tried as you said : Switch off the OP, set the PLC to STOP mode and then restart both units. During startup, set the OP to download mode, download the configuration again and then restart the OP and PLC again. But the same error is there. I already ask my client to send it to Siemens for Service. Thanks, Pratts23.
