communication
8.1
Entering settings
M11735-2 v1
If the IED is connected to a monitoring or control system via the rear SPA/IEC port, the
SPA/IEC port has to be set either for SPA or IEC use.
8.1.1
Entering SPA settings
M11735-7 v4
The SPA/IEC port is located on the rear side of the IED. Two types of interfaces can be used:
•
for plastic fibers with connector type HFBR
•
for glass fibers with connectors type ST
When using the SPA protocol, the rear SPA/IEC port must be set for SPA use.
Procedure
1.
Set the operation of the rear optical SPA/IEC port to “SPA”.
The operation of the rear SPA port can be found on the local HMI under Main menu/
Configuration/Communication/Station communication/Port configuration/SLM
optical serial port/PROTOCOL:1
When the setting is entered the IED restarts automatically. After the restart the SPA/IEC
port operates as a SPA port.
2.
Set the slave number and baud rate for the rear SPA port
The slave number and baud rate can be found on the local HMI under Main menu/
Configuration/Communication/Station communication/SPA/SPA:1
Set the same slave number and baud rate as set in the SMS system for the IED.
8.1.2
Entering IEC settings
M11735-32 v4
When using the IEC protocol, the rear SPA/IEC port must be set for IEC use.
Two types of interfaces can be used:
•
for plastic fibers with connector type HFBR
•
for glass fibers with connectors type ST
Procedure
1.
Set the operation of the rear SPA/IEC port to “IEC”.
The operation of the rear SPA/IEC port can be found on the local HMI under Main menu/
Configuration/Communication/SLM configuration/Rear optical SPA-IEC-DNP port/
