1. Set the port for IEC use on the local HMI under Main menu /
Configuration /Communication /Station communication/Port
configuration/SLM optical serial port/PROT
OCOL:1. When the
communication protocol is selected, the IED is automatically restarted, and
the port then operates as an IEC port.
2. Set the SlaveAddress and BaudRate for the rear IEC port on the local HMI
under Main menu/Configuration/Communication/Station
communication/IEC60870-5-103/OPTICAL103:1. Use the same settings
for these as is set in the SMS system for the IED.
6.2 Verifying the communication
M11735-77 v1
To verify that the rear communication with the SMS/SCS system is working, there
are some different methods. Choose one of the following.
6.2.1 Verifying SPA communication
M11735-81 v5
Procedure
1. Use a SPA-emulator and send “RF” to the IED. The answer from the IED
should be the type and version of it, for example, “REL670 2.1...”.
2. Generate one binary event by activating a function, which is configured to an
EVENT block where the used input is set to generate events on SPA. The
configuration must be made with the PCM600 software. Verify that the event
is presented in the SMS/SCS system.
During the following tests of the different functions in the IED, verify that the
events and indications in the SMS/SCS system are as expected.
6.2.2 Verifying IEC communication
M11735-91 v2
To verify that the IEC communication with the IEC master system is working,
there are some different methods. Choose one of the following.
Procedure
1. Check that the master system time-out for response from the IED, for
example after a setting change, is > 40 seconds.
2. Use a protocol analyzer and record the communication between the IED and
the IEC master. Check in the protocol analyzer’s log that the IED answers the
master messages.
3. Generate one binary event by activating a function that is configured to an
event block where the used input is set to generate events on IEC. The
configuration must be made with the PCM600 software. Verify that the event
is presented in the IEC master system.
