Remote controller upgrade

If your controller is connected to a Supervisor, upgrade the Supervisor first and then upgrade the controller station from the Supervisor.

The procedures in this section are unique to upgrading a controller. There are several reasons to upgrade the software in a controller:

  • A new version of software has come out.
  • The company wants to implement new features.
  • The controller needs to be replaced with a new controller of the same model.
  • The controller is being replaced by a different model controller.

If the upgrade is replacing the current software without making a hardware change, you should back up the station by making a distribution file backup or a station copy, but you may not need to restore the station after the upgrade.

If you are replacing the controller with a new controller of the same model, a distribution backup of the station is the recommended best practice for upgrading the software.

If you are replacing the controller with a different model, a distribution file will not work. You must make a copy of the station instead.
