Operations

In this section it is possible to form a set of predefined actions. The actions are executed with:

pressing the execution button (at the section, in context menu of the object/link, or on the widget),
trigger actuation (actions on state changes).

Operations can be used in order to:

change state of controlled object/link,
change parameters of controlled object/link,
obtain data from controlled object (parameters, configuration, software version etc), upload software updates to the object.

This section is available only for users with rights to run operations.

Only users with rights to manage operations can add, edit and delete operations.

It is possible to add a set of default operations to an object class in the System configuration window.
