If this property is set to True, this I/O Driver shares its execution among all other I/O Drivers with the same String in the DriverLocation property. This means that only the first configured I/O Driver executes the communication's initialization procedure. All other shared I/O Drivers ignore all setting parameters from P1 to P4, as well as other settings. Otherwise, if this property is set to False, this I/O Driver does not share any kind of communication with other I/O Drivers. This property cannot be modified once communication starts. Default value is False.
