20.6.2.1 Settings for RS485 and optical serial communication

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)
