Declan Byrne Posted March 23, 2017 Report Share Posted March 23, 2017 Hi, Pretty simple question but for some reason as a beginner I am having trouble finding out. When using a snap-on IO and then an Expansion module and IO, how do I enter my inputs into my program after I have filled my snap-on IO Number wise? When the next IO starts at I0 does it matter what number the input isin the program in regards to hard wiring into the module? eg; I have room for 18 digital inputs, I am only using 14 on my snap-on IO, on my next IO I am using 13 of the 16 digital inputs, I will number my inputs in entered in my program 0-13 regards to how they are hard wired, i have On my next IO what number do I start on in my program considering my IO Starts at I0 in regards to my hard wired cables? I hope this makes sense. Thanks Quote Link to comment Share on other sites More sharing options...

When you configure your I/O in the Hardware Configuration dialog, it will tell you what the addresses will be on each module. I know this is confusing. There are little stickers included with each expansion module so you can re-label them as to what they really are. Joe T. Quote Link to comment Share on other sites More sharing options...
