Hello, I am dealing with some old L35E controllers with old programs from the early 2000's. I was perusing them and discovered that the original programmer used Function Blocks in some places to make very simple decisions like the following. This leaves me scratching my head to determine ***WHY*** they would use a FBD for this instead of a simple ladder contact. Almost everything else is ladder logic in their program except for some FBD totalizers (which make a bit more sense, but still...)
Any idea why this would have been done? is it a performance enhancement? Definitely NOT better for readability! This is the ONLY item in the entire function block - no extra pages, etc... so they created it specifically to make this one decision.
