Explanation
At least one of the access points configured for GOOSE is
disabled. The port can be disabled either through
changing the access point operation to off or by
unchecking the GOOSE protocol from the access point in
the Ethernet configuration in PCM600 or LHMI.
Enable GOOSE on access points:
<Access Points>, can be any of these: AP_FRONT,
AP_1, AP_2, AP_3, AP_4, AP_5, AP_6,AP_7, AP_8
OEM in pos <slot number> is running the factory image
instead of the application image. The factory image is
older than the required FW version and does not contain
the latest updates and fixes.
Reboot the IED. If the problem persists, update the OEM
firmware or replace the board.
Merging unit has no access point.
Check AP configuration.
Check cycle time for SMAI and 3PHSUM blocks
connected to Disturbance Report blocks. SMAI and
3PHSUM blocks shall have the same cycle time.
LDCM transmitter is missing connections. Check the
LDCMTRN block.
System frequency is different in local and remote end of
LDCM link.
Check the parameter FrequencySel at both ends.
