    This is a quick bit of code to show how a recipe function might be written if one were to do it in the PLC rather than the HMI. This is the basic building blocks with which a program could begin to be written. The BSET instruction combined with the indirect addressing method demonstrated would allow for a delete function. Copy and other functionality could be added using similar concepts.

  3. Is it possible to make the ladder logic display the name, address and comment? If so how can i do this? Thank you, Mike

    hello, I have just joined Mr PLC so apologies if my question is answered elsewhere that I ought to have seen. I have just started to learn GX Developer and have produced a basic ladder diagram with just six rungs. When I print it A4 the result is far too small meaning any text cannot be read. I can find no way of making it print "fit the page" Can anyone advise me? Roger
  5. I'm just starting to learn Ladder Logic Programming. I'm using Allen Bradley RSLogix 5000. I've been tasked with developing a 'Simple' Coffee Machine which operates like so: Toggle Push Button to StartDrop Cup (for 10 seconds)Feed Hot Water (for 10 seconds)If required, Add Milk (for 10 seconds)If required, Add Sugar (for 10 seconds)Procedure Complete - Illuminate Complete Light (for 10 seconds)I have implemented everything except the OPTIONAL add Milk & OPTIONAL add Sugar. Options are: To have a Coffee without either Milk or Sugar.Or have a Coffee with Milk and Not Sugar.Or have a Coffee with Sugar & Not Milk.Or have a Coffee with BOTH Sugar & Milk. I'm considering using Toggle Buttons to select / jump to a Subroutine (choosing the required ingredient make-up). But I'm wondering if there is another way to sequentially go through the procedure? Thanks. http://stackoverflow.com/questions/26930902/ladder-logic-simple-coffee-machine-optional-add-milk-add-sugar?noredirect=1#comment42839041_26930902
