Jon Posted October 25, 2010 Report Share Posted October 25, 2010 Let me start by saying I do not know much about ladder logic programming. I was thrown into this like baptism by fire. Soo... I have a simple ladder logic program for a set of rollers, like a winder, that changes tensions based on input values. I am attempting to modify to accommodate a "recipe" page. I have the whole HMI screens setup based off of another machine in the plant. Problem is, it is all in German (the program is set to English but the notes/labels are German) so I cannot simply look over the program and figure it out from their program. There are multiple boxes where a value of some sort can be set via keypad. On the other machine, there is a "Save Recipe" button which saves all settings to a specified recipe name (output to a list of recipes where you an choose one). There is also an "Apply Recipe" in the list. The Question: What would be the most simply way to do this? Do I need to specify a group of MI variables like 0-9, 10-19, 20-29, etc.. (based on how many variables there happens to be) and copy and paste like 50 times (for total of 50 possible recipes)? So when I hit save recipe, it looks for next available set of variables to define or will it automatically find a group of variables the correct size and start defining itself? And finally... am I getting myself in over my head with trying to figure this out? Am I better off hiring trained programmers to finish this? Ladder logic doesn't seem too difficult as I am able to modify what it there and understand what it does but I don't know what the program is capable of so I don't know what I can/cannot add. Thanks if you read through the whole post and did not chuckle at the simplicity of the problem Quote Link to comment Share on other sites More sharing options...
