I'm trying to set up Modbus on the IG502 and the data type defaults to "BIT" but it is a 16-bit word or 32-bit word. 

Why can't this be changed? 

I'm also trying to post a picture here to show issues but this site will not let you even though it is an option when you post.   It shows an error but it is not in english.  

Are there no better instructions anywhere?
