Hello! I am trying to make a request to the slave using modbusRTU(RS485) S7-1200 -> ET200SP -> CM_PtP(master) -> ModiconM221(slave). In the handbook recommended use MB_COMM_LOAD and MB_MASTER. When the function MB_KOMM_LOAD is called it occurs error and the status = 16#8180. Why such an error can occur, and what can I do to successfully read information from the slave device?
