Hi, I have quesstion about Modbus Slave communication. I look at your example and config my module like your (i need to receive data to DB800) and when monitor the FB80 i see that CP_START_Error = 1 Error_NR =0002 and i have no communikation. I attach my CP parametr. And when i try to test communication with ModScan there is response to 1-st and 2-nd function (responce with rerror) but for 3-rd and 4-rd function is no responce at all.

Hello TblMb, I think you inserted a wrong LADDR when calling FB80 - just compare it with the one in HW-Config. Regards, Kaulquappe |

Hello Johnny, after storing the parameterization in HW-Config you must load it. It is not possible to simulate CPs with PLCSIM. Regards, Kaulquappe |
