I read diagnostic buffer and see many lines: SFC 12 not loaded, address xxx. I tried to download SFC12 from standard library to PLC but when I go online, I can not see SFC12. In hardware config, the firmware is V1.0. On front face of PLC, I can see V1.0 too. What should I do ? Please help me.

Having a look at this dokument: Deactivating and Activating DP slaves there they wrote that it is supportet from Firmware from firmware V1.2.0 on. Here you could download newer firmware for your CPU: Operating system updates for S7 318-2 CPUs Good luck Sabine
