vincLafla Posts: 7 Rating: (0)	I also have a communication problem with my cpu plc 226. I have step 7 Micro Win v4.0 Sp2 program. In communication screen I can refresh and I can see my Cpu 226 Rel 01 22. So the communication between cpu and my pc seems to be o.k. But when I try to upload the program from cpu to pc it write: Binary data loadedfrom the CPU altered. ( I translated it from french so it's possible that it isn't exactly the good sentences). Can some1 help me plz ? vincent Splitted from S7 200 Upload Failure.

Is this errorstaying there doesn't matter what did you select in upload options. I mean - Program block - Data block - System block Best regards, Hristo Mihalev
