How To > How to remember variable values when the device is powered off

You want to remember variable values when the device is shut down and use them when it is started again.

The most important setting is the property Remanent in the Variable Manager.

The property can only be activated for user-defined variables with the PClient as the owner.

For pre-defined variables or variables with an owner other than the PClient this setting is not possible.

Remanent variable values will be saved on the file system automatically, whenever their value changes.

Removing power completely (disconnect clamp 15) directly after a value change might lead to the loss of the last change.

Please note: When a project update with the same name is downloaded to the device, the remanent variable values will be kept.

If a project with a different name is installed on the device, the remanent variable values from the old project are not used. However, they will still be stored on the device, so if the old project (i.e. a project with the old name) is installed, the remanent variable values are used.
