3.1 General Ethernet Communications Trouble Shooting
If you are having trouble communicating with the RA24 IED or other subscribing IEDs check the
following:
Item
Description
1
Check that the Station Bus Lan is active and functioning
2
Check that the RA24 IED and the subscribing IED Ethernet ports are
active and communicating by checking the port activity LEDs
3
Undertake a ping test on the RA24 IED and the subscribing IEDs
4
Confirm the IP addressing for each of the devices is correct as
determined by the Substation topology (check the devices are on the
same Subnet) and that devices connected on the same Subnet have
unique addresses
3.2 IEC61850 GOOSE Message Trouble Shooting
If a SARC GOOSE is not being received by a subscribing IED check the following:
Item
Description
1
Check that the required SARC is enabled in the RA24
2
For a current check scheme is the current check element enabled
and being picked up?
3
Check the GOOSE linkages in the Substation Project and ensure
that the correct sources and subscriptions have been established
4
Check that the Subscribing IED logic is consistent with the Subscribed
SARC. If required troubleshoot the logic by observing the
individual incoming signals are consistent with your test conditions for
example
Is the correct GGIO being received?
Is the quality bit being correctly treated?
Is the current check qualification being asserted
5
Using the RA24 Web Browser check for any error messages on the
Status screen when you FTP the .cid file into the device
6
In the Web Browser observe the trip status when a Sensor is
triggered
7
Using and IEC61850 browser such as IED Scout observe the trip
