This PLC code can handle any number of recipes with any number of ingredients, limited only by the PLC memory. It allows the user to enter the recipe number to work with using a C-More panel.
It works just fine from PLC 05 to PLC 260. After performing quite a testing on the code I notice the following:
Once you enter 10 recipes, for example, and decide to go back to recipe #3 and change the values on each of the ingredient then and push “SAVE”, the next recipe that follows, in this case, recipe #4 all the ingredient values changes to “0”. I have no idea why it does that.
Can anyone see where the BUG in this code is?
