IEC21000003 V1 EN-US
Figure 13:
AP3 configured with RSTP
RSTP will only be available either on the Access Point, AP 1 or AP 3. AP1 uses port
1 and port 2; AP3 uses port 3 and port 4.
When any of the Access Point is configured with RSTP or changed from RSTP, the
IED will reboot to load the new ethernet configuration.
The IED will display hints on LHMI if any error in the configuration is detected.
For IEC 61850 ED2, the new sub-network can be changed but it is recommend to
configure all the devices in a ring to the same access point. Due to a limitation in
ECT, it does not allow to edit the subnet for WA1 because it is dedicated to a station
bus access point, and AP1 is configured by default in the IED SCL model.
