Hi all, I have a general question on PLC logic. Just wondering what is the difference between phase and sequence logic when related to PLC programming, thanks in advance,
Not exactly sure but I’ll give it a go. Typically when in the requirements gathering phase of a project you would like to break the large problem into smaller, more bite size type problems that you can code out. I’m guessing here, but if I had to code a large machine, I may be inclined to break that down into logical blocks or portions (or phases) and then each phase would have its own sequence.
If you’re referring to a PLC programming type paradigm, or style such as FBD, Ladder or SFC, I’m not familiar with phase or sequence.
Thanks for the reply, just curious more than anything, I recently did a project involving recipe manager for a factory, they asked me was I using phase or sequence logic. Sequence logic seems relatively self explanatory and your view on phase logic makes sense
