Determines whether CitectSCADA attempts to call the StopChannel() function for a driver.
The StopChannel call releases resources allocated for a PLC connection. Under normal circumstances, this occurs when the PLC is online at shutdown, or disabled. Since the PLC may not get a StopChannel when it is offline at shutdown, its resources may not have been released and CitectSCADA crashes can occur.
By default this parameter is set to 1which means that a StopChannel is called, and may prevent crashes at shutdown. Usually if setting AlwaysCallStopUnit, you would set AlwaysCallStopChannel.
Default Value: 1
