I am perplexed. I am using an analog sensor output 0-10vdc into a micrologix 1400 analog in channel 0, there are no other analog inputs present. Using a scope at the analog input terminals, I can verify that the analog sensor is putting out a clean 0 - 10vdc as the sensor operates. However, looking at the I:0.4 contents in decimal format, the a/d conversion ranges about .2 - .4 vdc less than actual voltage at the terminal. Any ideas?
