Mismatch uploaded S7-200 program and CPU

Post by k_alexis »

Hello All! I have some problem. There is a press HUNKELER with S7-224XP with 3 expansion modules and OP77A. The controller does not have an inserted memory card. I don't have the original program and I uploaded it from the controller on the laptop using the “PC Adapter USB” cabel in STEP7-Micro/Win v4.0.8.xx. When comparing programs in the CPU and loaded from the CPU is detected difference time stamp in the one of blocks. Difference =1 sec. In the monitor mode, observed a strange logical inconsistencies, for example, the mismatch of the status of output Q and condition in the program. Or for exampe, by logic the output must be ON, but in program status is OFF. When tabular monitoring the state that corresponds. Machine works, but there are some questions to logic. The problem occurs when downloading from both ports.
I tried it for about 5-6 times. Same problem.

What could it be? Damage the controller? How to solve the problem.

Sorry for my english.

Check if the outputs are referenced twice.

Possible that the second ladder is overriding the first ladder and then you start to have weird things happening like what you are seeing.

No. All outputs only in one place.
In "Chart Status" signals are OK, The condition match with the real outputs. Not like in online blocks.

I see it if I scrolling down block in online
