One of my engineers was on site doing a commissioning of a sister company's equipment. The PLC is one of the newer S7-1500 types. The original program was written with TIA Portal V13 SP1. My guy has the latest version of TIA Portal V13 SP2. Our procedures are to always upload what is in the PLC before doing anything else, so that's what he tried to do.
He opened a new, blank project, and unsuccessfully tried to upload. He didn't tell me the exact error message, but it was something like, "The hardware configuration was created and downloaded with an incompatible version of Step7. Could not upload hardware configuration."
Heretofore, an updated version of Step 7 could always access a program written with an older version. Was my guy doing something wrong, or is this a possibility with TIA Portal?
As this was a sister company, they sent an updated program to work with, so this was a slowdown and an inconvenience, but if we come across another system without the original program, this could be a problem.
Can anyone give me any wisdom in this situation?
Thanks for reading.
