Can't lose with 42s
Anybody on here do what I do for a living?
Me too, I work in the aggregate industry, I design the wet side of the plant. Minus 4 mesh. I started doing plc instead of controllers about 3 years back. Most of my controls are simple analog and digital layouts. The most complicated thing is a PID loop. That’s pretty much equivalent to a thermostat in your house. I use Allen Bradley logix 5000 software and compact logix for my processor.Kinda.
Some Allen Bradly stuff, and only if I have the right software and hardware to interface the controller. And then I use it to only trouble shoot. If I get involed in any minor loops and tuning them, that is a recipe for disater. But once set up correctly, the only thing needed is going it to find out why something is wrong, or where the program is stuck.
But mostly deal with BAS/BEMS stuff, like Honeywell, Siemens, Trane, but not at an admistrators level. And then there is all the stuf on refrigeration equtiptmen I deal with like Trane and York and those particulars on chiller/ac control panels.
I hate relay logic, you want to give me a headache in 3 minutes then ask me to figure out a problem on a redundant relay logic system (with prints of course).
Yes, proportion intergral derivitive except I don't fuck with the D, then you are asking for trouble.Yep, relay logic gives me a freakin headache too man..I feel ya....
Talking about loops - are you talking about PID?
PID is either your best friend, or your worst enemy. Tuning them can be a disaster...
