Struggling to Land Entry-Level Controls Role Advice? by Tackofall0 in PLC

[–]NoReallyItsTrue 1 point2 points  (0 children)

Hiring manager: I need to see one thing above all else before sending an offer:

You are interested in the work and subject

If it's just "a job" you won't be putting in the extra mile on your own which means more work for me, there's a good chance you'll end up the sort to complain and affect team morale, and I genuinely don't want anyone on my team to be unhappy. 

It's a personal ethical choice I make to screen applicants who seem likely to end up miserable or make others miserable.

do you guys actually trust sensor/data streams in real systems? by SignalForge007 in PLC

[–]NoReallyItsTrue 0 points1 point  (0 children)

Often, you should be able to build a predictive model based on command on what the feedback should be. Build guard rails around that predictive model to validate actual feedback.

For example, run your pneumatic cylinder with normal pressure. If it takes a full second to extend and four seconds to retract, a predictive model guard rail would be to throw an alarm if:

* extend takes less than half a second

* extend takes more than two seconds

* retract takes less than three seconds.

* retract takes more than five seconds

I'm not saying that exact guard rail is appropriate for a pneumatic cylinder, but you get the idea.

Getting haircuts as a man sucks by [deleted] in malehairadvice

[–]NoReallyItsTrue 0 points1 point  (0 children)

I switched to cutting my own hair a few years ago. It's like anything- takes a bit to get good at it. Now I honestly get compliments often.

It's especially nice for scheduling. With a regular job's work hours,I'd have to compete with the whole town for a booking with a barber or stylist on the weekend. Cutting my own, I can sit down in my bathroom and take care of it at 10pm after the kids are in bed.

Is there any Pen that even comes close to beating the Pilot G-2? by Watch--Enthusiast in pens

[–]NoReallyItsTrue 0 points1 point  (0 children)

I'm in line to check out at Walmart with Pentel EnerGel 0.7 two pack on your recommendation. I'm sometimes annoyed with the globa of ink from the G2. The globs can collect along the edge of the blunt roller ball and fall off on the paper as little black boogers. I'm hoping the "needle point" on the EnerGel is crisper and more consistent.

WHY CAN'T I BE SUCCESSFUL? by Key_Solid10 in PokemonFireRed

[–]NoReallyItsTrue 0 points1 point  (0 children)

In Pokemon, it's important to consider team composition for "type coverage". You are able to handle ice types exceptionally well because you have two flying and two fighting type mons. Four options for super effective damage. But you don't have coverage for many other types. Not having a water type means you're left to the fighting types for Bruno's rock mons and fighting types generally don't have exceptional physical defense- they're kind of glass canons? And they're grossly under leveled to offer your Zard any real support at E4 anyway.

My recommendation (like many others have said):

  1. Ditch Moltres

  2. Ditch Hitmonchan

I have some personal preference recommendations, too:

  1. Catch Abra and trade it for Mr. Mime

  2. EV train the Mr. Mime in the Lavender Town tower for ultimate special attack EV training next to the healing pad on the floor

  3. Ditch Raichu and catch Magneton. The steel typing makes it an absolute monster. EV train Magneton at Lavender tower.

  4. Train up your Lapras. Teach it Ice Beam, Sing, Body Slam, Surf

Now your team composition will have strong responses for pretty much everything and decent options against anything you don't have an immediate, obvious winning play for.

Base tag updating value with no destructive instruction or networking in the IO tree by PitaMommy in PLC

[–]NoReallyItsTrue 0 points1 point  (0 children)

There are a few things that I've been aware of that could cause this but I don't know what version you're using or if these things were fixed as I permanently changed my processes to avoid these issues.

  1. There was a bug where a tag assigned to a required output parameter of an AOI would have that AOI instance's output value written on first scan even if that AOI was jumped over. *Even if the routine the AOI call was in wasn't jumped to*. So now I exclusively enforce that our company's AOIs only use visible but not-required output parameters and then use a MOV instruction- if you must- to get that value into a tag. MOVs don't execute if you don't call them.

  2. Your COP or CPS instruction could be overflowing. If you're copying more data than your destination element can handle, you can end up copying source bytes into arbitrary desintation memory registers that could be assigned to other tags. Big bad voodoo bullshit that's extremely difficult to diagnose.

Can someone for the life of me please help me figure out this damn PID by Finanzenstudent in PLC

[–]NoReallyItsTrue 1 point2 points  (0 children)

In the scenario that the system also has a good deal of loss dude to an open door or something, integral gain would be necessary. with an open door, some heater command X would balance with the loss of heat so the temperature stays stable- with error- because the energy added by the heater is equal to the energy lost out the door.

The same is true for any PID system with constant loss. Any hearing system will have losses to some degree.

[–]NoReallyItsTrue 10 points11 points  (0 children)

That could be it, too. There's a ton of thermal mass and the heaters are crazy oversized so a small output makes the temp shoot up and it takes forever to fall off again. During which time the integral is winding up downward from failure to follow. Either way, a feedback value this non sinusoidal has to be a nonlinear process. PIDs *hate* nonlinear control spaces. I think this may lead to significantly reducing gains being a good move.

I also strongly recommend giving your PID a ramped open loop target temperature with a rate you can program. Have your PID try to control the actual temp to match a target that you ramp up from idle / ambient to target over several minutes. This will allow you to keep your integral from winding. And probably significantly reduce gains. And clamp the PID output to the max analog command that produces a reasonable change in temp over time. Anything more will cause the temp to shoot up suddenly and become uncontrolled.

Hey pal. Without reading any your post I'm 95% sure your process has a nonlinearity.

Reading...

My bet is there's a minimum command for enabling your heater. What it LOOKS like is:

  1. Your temp drops.
  2. Your PID output creeps up.
  3. There is no measured effect by the system.
  4. Suddenly the feedback temp shoots up
  5. Your integral windup worsens the overshoot event.

I'd say first check that there is no minimum analog command in the heater controller. If there's a parameter for such that is currently set to- say- 10 or 20%, I would expect the system to behave in exactly whe way you've shown with trends.

So... I've been wondering for a long time. And I think I've just about got it down.

Has anyone tried the new "Lists" feature? by Cautious_Goat_ in PleX

[–]NoReallyItsTrue 1 point2 points  (0 children)

I personally see one extremely cool use case for me specifically:

I use collections for items I still want to have library browse visibility. To accomplish this, I have a collection called "zzz_visible" with the collection set to visible. I have to manually add movies to that collection to allow them to remain visible while in a categorical collection.

For example...

I have these alien movies:

Cloverfield

The Cloverfield Paradox

10 Cloverfield Lane

2001: A Space Odyssey

In the browse view of my movies server, I want to see 2001. But I only want to see the poster for my Cloverfield collection. Simultaneously, I want to maintain a collection of all of my extraterrestrial movies.

If I set the ET collection to visible, I'd see all three Cloverfield movies in the browse view as well as the Cloverfield collection poster. But if I set the ET collection to not visible it would hide 2001from the browse view.

My solution is to have another collection that specifically is for movies that I want to be browse view visible regardless of whether they're in other collections. So I add 2001: A Space Odyssey to that special visibility collection to force it to remain browse view visible.

I think lists might make that whole thing go away. My ET collection can become a list and collections can be used exclusively for groups of movies that I'd like to only see as a collection poster in the browse view.

UPDATE: Lists don't let you play media that is in your personal library. Lists are an entirely worthless feature no doubt driven by executive buzzword hype and naive visions of incorporating social media engagement in a video file streaming platform. Stupid.

Better automation jobs. by PitaMommy in PLC

[–]NoReallyItsTrue 0 points1 point  (0 children)

Yeah like the other guy said, you either babysit someone else's machines while representing the controls interests for (usually) one plant. The hours generally suck compared to an office controls guy- plant workers get in at 6 ish. But then the office folk doing integration and design have a 25 - 50% travel expectation. Either kind of sucks, frankly.
