I have a PLC which is not saving the project in the normal way.

Project File Status = Not Saved

CPU Project Status = Out Of Date

Transfer the project to the PLC and

Project File Status = Not Saved

CPU Project Status = Up to Date

Now save the file to the PC and

Project File Status = Saved

CPU Project Status = Out Of Date

Transfer the project to the PLC and

Project File Status = Not Saved

CPU Project Status = Up to Date

I can not get the two of them to be happy with the saved project, either one is out of date or the other is not saved. If I close the project and then reconnect it will say that there is Project Differences, but I know that they are the same. The only error showing on the error history is E04204 DL Buffer> 50% Full and memory usage is 6%. n111436

In your task named "Loading Bay Temperatures " you have a subrung "3.1 " that has an END, but is not attached to rung 3. Delete this subrung and it should save.

{ "alt ": "Click image for larger version Name:\tRung.JPG Views:\t1 Size:\t36.4 KB ID:\t111458 ", "data-align ": "none ", "data-attachmentid ": "111458 ", "data-size ": "full ", "title ": "Rung.JPG "}

Maybe an update so the software could flag that.

Why isn't the compiler giving an error on that? More so, why is that an issue at all?

Interestingly, I ran into the very same problem today. Save program> Program Up to date. Transfer program (runtime)> CPU up to date, but then immediately the program would not be up to day. Re-save the program> program up to date, immediately CPU becomes not up to date.

Closed everything out, rebooted laptop (it had been up for quite a few days without a reboot), issue disappeared.
