16.6.2.1 Settings for RS485 and optical serial communication M17109-118 v12General settingsSPA, DNP and IEC 60870-5-103 can be configured to operate on the SLM opticalserial port while DNP and IEC 60870-5-103 additionally can utilize the RS485port. A single protocol can be active on a given physical port at any time.Two different areas in the HMI are used to configure the IEC 60870-5-103protocol.1.
