Posted 13 May 2005 I'm using the V280 with a IO-AI4-AO2 expansion module. When compiling the project with the "_Interupt 2.5ms" Routine and having the Immediate Analog Out FB in that routine I get a compile error #705, stating "The define hardware configuration does not support immediate analog output 0. Is this because the Expansion module is not capable of the 2.5ms immediate out? Thanks DonH Share this post Link to post Share on other sites
