Settings for RS485 and optical serial communication M17109-118 v11General settingsSPA, DNP and IEC 60870-5-103 can be configured to operate on the SLM optical serial portwhile DNP and IEC 60870-5-103 only can utilize the RS485 port. A single protocol can be activeon a given physical port at any time.Two different areas in the HMI are used to configure the IEC 60870-5-103 protocol.1. The port specific IEC 60870-5-103 protocol parameters are configured under:Main menu/Configuration/Communication/Station Communication/IEC60870-5-103/• • SlaveAddress• BaudRate• RevPolarity (optical channel only)• CycMeasRepTime• MasterTimeDomain• TimeSyncMode• EvalTimeAccuracy• EventRepMode• CmdMode• RepIntermediatePos is:• “OPTICAL103:1” for the optical serial channel on the SLM• “RS485103:1” for the RS485 port2.
