We have a plant with 4 PLCs Slimline Cortex M7. When we go to connect to a PLC, the development IDE shows us “CODE DIFF. (SIM) ". To understand where we were wrong, we loaded the program (which is different for each PLC, and is stored in separate folders) in each PLC, trying to log out and log back in immediately afterwards, all successful. But one of the PLCs gave us “CODE DIFF. (SIM) ". After each download, we made a copy of the project folder, to make sure we have a file exactly the same as the one downloaded to the PLC. Where are we wrong?
Now I reloaded the projects starting from the PLC-1 up to the PLC-4, doing the test for each single PLC of reconnection both from the original folder and from the copy, with a positive result.
The problem of the incorrect "CODE DIFF. (SIM) ”of LogicLab to connect with PLCs SlimLine it is a known problem that we have already reported several times to Axel which develops the LogicLab environment. Unfortunately, despite several changes, we have not yet been able to reach a complete solution to the problem.
We are working on a new version of LogicLab that is currently being tested by us and we hope with this version to get to the solution of the problem.
