Recipe Sample Code - Ladder program with supporting NB project
Michael Walsh posted a file in PLC Sample Code

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. -

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

Ladder Logic - 'Simple' Coffee Machine - Optional: Add Milk / Add Sugar
flipd.d.mon posted a topic in Allen Bradley / Rockwell Automation
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- 2 replies
