Have a look at the specifications that @AutoGen_1835473 gave in the start of the topic. Make sure you comply.. especially the firmware version. (PLC S7-1200 G2 Midbus RTU communication problem) Record the fault state of the ..Load instruction. Note that the error state is held only for one scan. So you need to capture (store) the error state value in a tag. Analyse the error identity for a remedy. Show a screen capture of your situation thereafter. Place multiple images in a ZIP. Use the classic forum interface to attach that ZIP to your response. |
