Description
Indicates the source of the trigger input. This trigger tells the switch module to advance to the next entry in the scan list and close the specified channel. The IVISWTCH_VAL_IMMEDIATE value indicates that the switch module does not wait for a trigger before starting the next entry in the scan. This is typically done for switch modules that support the IVISWTCH_ATTR_SCAN_DELAY attribute and can therefore have the switch module pace itself. The IVISWTCH_VAL_EXTERNAL value means the trigger is coming from an external source through a trigger input connection.
If the switch module is currently scanning through the scan list, setting this attribute returns the error IVISWTCH_ERROR_SCAN_IN_PROGRESS.
