Here are additional info you requested: Step5 v7.1 COM DB1 v1.2 Connection to the PLC through serial port with Siemens S5 cable. There is anS5OP connected on second of the 943. We're able to get online status with PLC, but after we're not able to access program. As previously said, DB1 modification had been attempted with power off/on of the PLC with no success. Here enclosed print screens of what we can see from application backup (but we are not sure it is the last one). COM DB1 picture shows parameters values (no value in software protection !!) through COM DB1 software. DB1 shows the content of DB1 through Step5 it seems weird. Thanks in advance, Phlip
