What to do if no video file can be saved in the Mitsubishi Electric Controller network storage?
- H
  heather14Aug 29, 2025
  If your Mitsubishi Electric Controller isn't saving video files to the network storage, consider the following: If the same port number is set to the programmable controllers in "External Device Configuration", the simultaneous socket communications cannot be performed, so set different port numbers to each programmable controller and execute the FB again. Also, the open processing may have failed to complete at the specified connection number, so try restarting the programmable controller and the network camera, then execute the FB again.
