First Program Scan

3 posts in this topic

Hello all, I work with both Allen Bradley and DirectLogic PLC's; the DirectLogic programming software has a special relay (sp0) that goes high for the first program scan only. Does RSLogix 500 have a similar relay? I am trying to write default set points to some integer files that will have new values written to them over time and I don't want the default values being re-written over the changes. Thanks! cmoyer

Thanks Ron! That did the trick. I am still relatively new to AB but I knew there had to be something like this. I spent 15 minutes going through the RSLogix help file before I realized that somebody here would probably know. There are a lot of goodies in the S data file that I was unaware of until now! Thanks again! cmoyer
