    Setting the digital output value to passthrough allows you to write directly to digital output channels through Scan Interface.

    Use the following syntax to configure a digital output channel for passthrough:

    <channel name> = passthrough, where <channel name> is the name of the digital output channel defined in the I/O Configuration table.
