I'm trying to figure out the logic behind a clamp solenoid closing, and this particular bit of logic isn't acting like I think it should, maybe someone can explain to me why my thinking is wrong on this? This is on a Mistubishi PLC, using GX Developer 8.28e. Thanks for your help in advance!
What I'm looking at:
--| |----[> K8 D5000]--------( )
The part that's throwing me for a loop, is the instruction in the square brackets, [> K8 D5000]
I was thinking it was supposed to mean if the value of D5000 is greater than 8, then the logic passes through? But as near as I can tell, D5000 is always valued at 0, and it's being interpreted as true, passing the logic through. Consequently, the solenoid is firing.
