EnableDisable is used to disable or enable an Object. The enable / disable operation applies to the Object in the UA Server. The call completes when the enable / disable operation is complete. The Server may or may not pass the enable / disable down to lower levels. This is Server specific behaviour.

Comments

The EnableDisable Method will disable or enable this Object. Once the state of an Object is changed by this Method (i.e. disabled) the state will be maintained until this Method is called again to change the state (i.e. enable). The Method will report if any error occurs while disabling or enabling the Object. Table 6 specifies the AddressSpace representation for the EnableDisable Method.
