If you have original project of OP3 then delete the project (when you turning up tha power supply press ESC+right Arrow+bottom Arrow key) and redownload it again. It is not possible to make upload of project in case you don't have it. Best regards, Hristo Mihalev

Tweety Posts: 3037 Rating: (192)	Hello, Is the error number correct? I have not found a such error message number in the manual. There is the message number 551. Here you should check the MPI station address and wiring. You can see the system messages in the manual at site A-1 Link to Communication manual Tweety

I hope you have the Protool source file in order to migrate to the sucessor OP. In the following FAQ, you will found the sucessor OP SIMATIC TD17, OP3, OP7 and OP17, Discontinuation effective 10/01/2007 Hope this helps.
