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.
When communication to the controller is lost, the output value of the passthrough channel will be set to False. Once communication is restored, Scan Interface will be able to write the output value to the passthrough channel.
