I am running 2 Beckhoff Industrial PC's that are identical, just different computer names and IP addresses. I connect remotely using “Choose Target” to PC2 from PC1 and it connects successfully. I have the most recent program file from PC2 copied onto PC1, but when I go online with the program (PLC2.pro) it always says “The program has changed! Download the new program?” I don’t understand why it does this. The versions are identical. Appreciate any feedback. Thank you.
