Just for my own sake, wouldn't it be easier and make more sense for Target PLC's to do a message read and not have the Master do a write? That way scheduling becomes less hassle. I've always found it easier to debug (especially for persons unfamiliar with the systems) to see a message read instruction instead of watching the target data tables value change and not finding where the values are coming from. I see a lot of MSG instruction questions on the forum and it seems most are trying to Write values out and it just got me thinking about how I have never really used the Write MSG instruction, only reads. I guess it's more of a philosophical and techique question more than anything else. Just wondering what opinions others have on the board here.
In general I'm referring to AB Logix5 and Logix500 affected controllers.
