Explanation
<device name> firmware version <version string> is not
accepted. The minimum accepted version is <version
string>.
Update the LDCM firmware or replace the board.
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.
SFP has been unplugged from the slot.
Check the connection.
Corresponding hardware(s) is set to fail.
Configured and the detected SFP(s) are different.
Corresponding hardware(s) is set to fail.
Restart IED and consider reconfigure of HW modules in
LHMI path: \Main menu\Configuration\Reconfigure
HW modules to get the updated hardware list.
Non Hitachi Power grids vendor SFP detected.
Corresponding hardware(s) is set to fail. Use Hitachi
Power grids approved SFP's.
Merging unit has no access point.
Check AP configuration.
FPGA version is not accepted.
If OEM or NUM FPGA code is of too low version, then
update.
Duplicate IP address detected.
Duplicate IP: <xxxx>
Access Point: <xxxx>
Access Point MAC: <xxxx>
IP duplicator's MAC: <xxxx>
Total: 81.3%
Core0: 64.2 %
Core1: 98.4%
Tips to reduce the CPU load:
Configure minimum number of functional blocks
Switch off functional blocks not in use
Switch off protocols not in use
Remove IEC 61850 data sets not in use
Configure minimum communication data points
The IED prevented from applying the user settings for
IMinChx, IMaxChx, ValueMinch, ValueMaxCh as they
result in incorrect zero point calculation. Settings are
reverted to default values.
MIM:pX Channels:Channel_numbers
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.
