Undefine()

avaliable

Remarks

This method deactivates monitoring of the linked control system variables.

The event VariableChange, usually executed on changing the value of a linked variable, is no longer executed.

Hint: This is not necessary, if the online variables are used in combination with zenOn VBA and the events FireActive or FireInactive of the project, as the method Undefine is executed internally at the time of the FireInactive.
