When I test the program in run-time, after I clicked a button which change the M0.0 value, it shows "Value could not be written to PLC". But I can change the memory value in the Chart Status in Step-7. Do I need to add a Area Pointer?Or I should assign some address for I/O in Step-7 first? My setting of the "controllers" in Pro/Tool: Driver:Simatic S7-200 V5.2 system:5x100ms OP Parameters: Address:1 Interface:DP/MPI Network Parameters: Profile:PPI Baud Rate:9.6 HSA:126 Number of Masters:1 Communication peer:Address:2 Anyone can help me? Thank a lot! Best Regards, Kevin
