Settings for RS485 and optical serial communication
M17109-118 v12
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)
