GenXMeds Posted January 20, 2019 Report Share Posted January 20, 2019 So I am completely new to PLCs and HMI, but I am engineer, so I think I should be able to figure this out. So either I have completely missed something or the snap in I/O I bought is not good. I am using 570 with V200-18-E3XB. All I want to do it put a analog voltage out to V0 and read it on my volt meter. I would post the 3 lines of codeI have, but don't know how. So I have AO 0 as 0-10V with tag MI0 on the snap in setup. I then linearize a 0-10000 scale to 0-4095 bits and label this as MI0. On the HMI i have output bit and voltage scaled and displayed correctly, but then there is nothing actually at AO0 and AO com. Shouldn't I have voltage here. hopefully I missed something and this snap in is not broken. Thanks Tyler Quote Link to comment Share on other sites More sharing options...
