Explanation
LDCM in <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 LDCM
firmware or replace the board.
The <firmware version> does not support 2M mode. Set the
LDCM to 64k bit mode.
<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 Energy vendor SFP detected.
Corresponding hardware(s) is set to fail. Use Hitachi Energy
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.
