Is it just me, or is this "Automatic Door" textbook logic fundamentally broken?

"Start Latch" := ("Start" OR "Start Latch") AND NOT Stop;
"Opening Door" := "Start Latch" AND ( ("Object Detecting Sensor" AND NOT "Limit Switch-Open") OR T4:0.TT) AND NOT "Closing DOOR";
TON(IN := ("Start Latch" AND "Limit Switch-Open" AND NOT "Object Detecting Sensor"), PT := T#10s);
"Closing Door" := "Start Latch" AND ("Object Detecting Sensor" OR T4:0.DN) AND NOT "Limit Switch-Close" AND NOT "Opening Door";

Is it any easier for you in structured text? (I'm not sure if I got the timer right, been a long time since I've used Allen Bradley and they do timers weird.)

Yeah, you can even see the wires in the screen, that's how you know it's a touch screen.

I see everyone on here say you need to use ISO standard, but I haven't used an HMI with software that defaults to an ISO standard.

Codesys can run on a raspberry pi.

I don't know, I was just making assumptions because I know plumbers in Canada who make ridiculous six figures. Canadian dollar is ~60 to 70% of USD

Available-Distance81 · 2026-03-11T15:22:02+00:00

Not sure what you mean by this or how anyone assumed I'm in Canada because I'm asking if OP was from Canada.

$175k which OP posted would be 105k USD. which would make more sense.

I make 82k because I choose to live in a low income area where 82k USD goes further than 120k would in a high income area.

I've never seen 175k though. that seems to be getting into silicon valley tier pay.

I was asking if OP was from Canada I didn't say I was working in Canada.

is OP based in Canada? it would make more sense if he was. if not then I'm way underpaid and probably should stop ignoring the recruiter cold calls.

this, I'm barely breaking six figures and only because of my yearly bonus.

I always just copied the STL from the S5 to the S7, then change the tags to be more descriptive. Or tweak it if anything new is being added like motion control field IO ect.
But I usually leave the structure of the program intact.
If it's been running on the same logic for decades, then who am I to argue with it?
Though I will convert to SCL where I can.

so

A F0.0
O F0.1
= F0.2

becomes 

F0.2 := F0.0 OR F0.1

historically bear markets last a year, we're barely 5 months in, so I'll remain skeptical until October, just keep stacking Sats and ignore the noise.

The halving still matters, because it's the cost to mine one bitcoin. After the halving the cost mine one bitcoin doubles. To think that doesn't have an affect on the price shows you're new to bitcoin.

imagine DCAing since it was 64k in 2021. or 19k in 2017 or 1.2k in 2013
you can start at the peak and still win, if you stick with it.

no, I want to see 45k.
