ModulePersInSync Property

Checks if the persistent data of the Module object is in sync with the real values of the controller.

Namespace:  ABB.Robotics.Controllers.RapidDomain
Assembly:  ABB.Robotics.Controllers (in ABB.Robotics.Controllers.dll) Version: 6.5.129.0
Syntax
C#
Copy
public bool PersInSync { get; }

Property Value

Type: Boolean
Returns true if persistent variables are in sync, false if there has been a change of any persistent data in the controller program memory. If false is returned a SyncPers call is required in order to update the Module object with the real values in the controller.
Exceptions
ExceptionCondition
GeneralExceptionA General Exception has occurred.
Remarks
Returns true if the module is write protected.
Examples
In this example a check is done each time the task is stopped to find out whether the values of the persistent variables of the module are in sync with the real values in the controller. If not a SyncPers call is made.
