Sd Card Synchronization Failure - HMS Anybus X-gateway Modbus-TCP User Manual

4.6 SD Card Synchronization Failure

In the event of applying a configuration or restoring a configuration from a backup file, the SD card
synchronization can fail. There are many possible reasons for an SD card write failure:
• The SD card is write-protected
• The configuration file on the SD card is write-protected
• The SD card memory is full
• The SD card file system is corrupt
• The SD card is damaged
If the SD card write process fails, the reboot cycle of the X-gateway will halt. The GW LED will indicate
"invalid configuration" and the SD LED will indicate "failure". See "Status LEDs" on page 17.
To eliminate the problem, follow the steps below:
1. Turn the X-gateway off.
2. Remove the SD card. Find the cause of the problem.
3. Insert an SD card.
Note: This SD card must not contain a configuration file. If it does, the configuration on the SD
card will overwrite the configuration on the X-gateway.
4. Turn the X-gateway on. The X-gateway will run the configuration that was applied or restored
when the SD card write process failed.
5. Apply the configuration in the X-gateway Management section to save the configuration to the
SD card.
6. Now, the SD card is synchronized with the X-gateway. Both the SD card and the X-gateway con-
tain the latest applied configuration.
