General settings
SPA, DNP and IEC 60870-5-103 can be configured to operate on the SLM optical
serial port while DNP and IEC 60870-5-103 additionally can utilize the RS485 port. 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 60870-5-103 protocol.
1. The port specific IEC 60870-5-103 protocol parameters are configured under:
Main menu/Configuration/Communication/Station Communication/
IEC60870-5-103/
• <config-selector>
• SlaveAddress
• BaudRate
• RevPolarity (optical channel only)
• CycMeasRepTime
• MasterTimeDomain
• TimeSyncMode
• EvalTimeAccuracy
• EventRepMode
• CmdMode
• RepIntermediatePos
<config-selector> is:
• “OPTICAL103:1” for the optical serial channel on the SLM
• “RS485103:1” for the RS485 port
2. The protocol to activate on a physical port is selected under:
Main menu/Configuration/Communication/Station Communication/Port
configuration/
• RS485 port
• RS485PROT:1 (off, DNP, IEC103)
• SLM optical serial port
• PROTOCOL:1 (off, DNP, IEC103, SPA)
