READDATAQFILE Active X Control

Description:

Returns the engineering units tag of a specified channel.

The channel is the logical channel in the index on the channel list, not the physical channel. For example, if the channel list is 1, 5, 8, 9, 10, and you want the engineering units tag of channel 8, you would set the channel argument of EUTag to 2. If you want the engineering units tag of channel 1, you would set the channel argument of EUTag to 0.
