I have a customer who has had this happen twice on one of their systems now with v13 of Unity, once by their system tech and again today by me.
The issue is we try to *start* making a simple change to the PLC program and Unity says the change cannot be made without building offline. When this happens, it appears something changes in the PLC or a non-project file because despite having NOT built or downloadeded any changes, the online status shows the red "DIFFERENT" on the status bar at the bottom of the Unity program window.
Even if we close Unity, reboot, and open a previously saved copy of the PLC program (has the original date and time stamp) which was known to match the program in the PLC just prior to this happening, we still get the DIFFERENT indicator.
As for the simple changes, their tech was trying to change the value of a numeric constant in a FB task, I was trying to change one variable to another existing variable on the input pin of a block in a FB task. This is routine stuff I've done 100s of times in Unity.
Trying to upload the PLC program fails with a generic error message.
They recently upgraded to v13, and I don't have a lot of time working in with v13 yet. I have logged many hours on v8, v9 and v11, and have never had this issue.
Any suggestions? I may get a window to download the offline, rebuilt program to the PLC tomorrow, but from conversations I've had with others who were around for the first incident (I was out-of-state), even that may not completely clear this up. Unfortunately with the holiday week most of the players who were involved in the first incident are out on vacation.
Does anyone know if there's another way to get around this? One person mentioned there may be some temporary files somewhere that can be deleted which may help and prevent the need for the download?
Thanks,
