just look at this poo poo




why do we have to use rusty poo poo languages like ladder, ST, block diagrams and SFC in the year 2014?

gently caress you beckhoff, gently caress you bosch, gently caress you siemens. i'm trying to integrate opc communication with your poo poo software in my .NET application and you're full of poo poo.

namespaces? code re-use? nah, never heard of that

gently caress yeah im gonna use a language that's older than my grandpa to run this factory. and im gonna use plc's which are basically just normal pc's but with a 100x factor in the price tag.

oh yeah, i forgot. it's "industrial" quality so you know the chip in that thing is more thoroughly tested!

need to make a real-time app? you need to use ST with a fixed cycle time. no, there's absolutely no other sane way to do it.

we plug the timing values into a gigantic fuckoff xlsm then print it out, sign it, scan it, email a pdf to a technician who finger-pokes it into the controller on a grey and black lcd display

the technician then writes the install date, mails the sheets back to us and it goes in a folder

its possible to gently caress up by a second then the controller freaks out and goes into red flash during rush hour

traffic signals suck

sounds like some hardcore as gently caress job security tho

people always gonna need dem traffic signals working, the more layers of inefficiency in the process due to short sighted government procurement the better

i took a course in PLCs once (it was in the curriculum as a computer networking course but there was PLCs in it for some reason) and the prof warned us at the beginning not to short the relays and blow out their coils. guess who shorted the relays

wtf is the difference between a PLC and a microcontroller like an arduino or whatever

how complicated can the state logic for a traffic light be

PLCs are like a box with lights on it and you plug stuff into it, and they don't cost 10 cents

from what I remember the PLC is designed to switch higher currents than a microcontroller board, the kind of currents you'd use to drive machinery or incandescent lights, and to keep doing this under harsher environmental conditions

ladder logic also has its purpose which is to describe the control system in a way that can be audited, kinda the same dream that motivated COBOL and i expect it's worked out the same way in practice
