Hi,

I don´t know this error code but I would check project with block-consistency if you can open it - perhaps you get mor informations then.

Dear forum user,

I will attach the list of all STEP 7 error code in the attachment , your error message is not listed there. There are 2 options IMHO:

1-  When you encounter the message ,check the STEP 7 remedies that are available under Details or help on this error.

2- Find the original project , in folder ApiLog open the Step7Bas.ver with  notepad. That is a document of the developer PC while programming the project. Try to create a machine (virtual/actual) like the original developer and open it again.

Kind regards,
