william Posted April 22, 2017 Share Posted April 22, 2017 I am trying to use a BUTTON and the SET TO action to write a new value to a channel. The channel is DEVICE TYPE = TEST, I/O TYPE = AtoD, Timing = 0. The channel is being updated with the AddValue() from a sequence. When I try use the SET TO button and put 20 in the 'NEW VALUE' field it writes a value like .999505(the old value was 12) to the channel . I don't know what other info you need to help me on this one; please advise. Thanks Bill Link to comment Share on other sites More sharing options...
AzeoTech Posted April 28, 2017 Share Posted April 28, 2017 That's because "setting" an A to D channel actually just triggers it to read the channel, which in the case of the Test device generates a part of a sine wave. You should instead make a Test D to A channel. Link to comment Share on other sites More sharing options...
