Hello, when a HMI displays #### this means that the problem is in communication, which Profibus connectors uses, original Siemens? The minimum length of the cable is "1 meter" (but I have also used shorter and it works the same) Bus fault with Profibus communication - Entries - Forum - Industry ..., 7 and 15 mt is not a problem, maybe it is the reflection of the cable, terminators are okay? |

Hello, Pay attention that the S7 200 is only SLAVE DP with EM277 What settings have to be made for a PROFIBUS DP connection ... but how the first and last are OFF, test first and last ON and OFF in the middle |
