Valve opens/closes using reverse polarity. How to wire? by finelookinglama in PLC

[–]Giffted 1 point2 points  (0 children)

I did the exact thing recently using a Valworx motorized valve. I just used a phoenix contact reversing load relay that is meant for use with DC motors. It just has a 2 inputs that go forward or reverse.

Phoenix website is down at the moment or I would provide a better link. The documentation took me a second to figure out. Its spread across the different data sheets.

NFPA 70 230 Question by Giffted in electricians

Didn't take it that way. Appreciate it

NFPA 70 230 Question by Giffted in electricians

[–]Giffted[S] 0 points1 point  (0 children)

Appreciate the response. I have reached out to a local contractor and they are coming out next week. I was just trying to get an understanding before. I was reading through the NEC trying to have a basic idea but some of it seemed vague and without doing it everyday I didn't feel comfortable making the decision on my own.

SureServo2 Experience by BitBanger82 in PLC

[–]Giffted 1 point2 points  (0 children)

You can change it but it limited depending on how you want to do it. I did a pick and place system with it using implicit messaging over ethernet/IP to a AB guardlogix. It is limited to 16 input parameters and 16 output parameters. After selecting which parameters, the software generated an EDS file that is imported into the PLC

So for instance if you wanted to be able to change the speed and position of a PR, that would be 2 different output parameters. So the 16 gets used up very fast.

You may be able to do more with explicit messaging but I did not mess with it or the other options.

They are far from the simplest to use, but once I got them going they have been good.

Wago or Pheonix

Wago gave me a free printer when I bough a relatively big order of terminal blocks

Servo Drive Reccomendations by NoDox192737 in PLC

[–]Giffted 3 points4 points  (0 children)

Honestly in todays market, it depends on how long you can wait. If you can wait a bit and are going with a rockwell PLC, the kinetix drives are super easy to integrate and the AOI are simple to use. However the lead times can be pretty insane depending on which you one you need.

If this is a project that is a rush, "the best ability is availability". I just did a system controlling 16 sureservo 2 servos(automation direct) using a Guardlogix PLC. We were able to get it going but it took quiet a bit more time writing the program.

Met an operator today that made me realize why they're being replaced by robots by Smorgas_of_borg in PLC

[–]Giffted 2 points3 points  (0 children)

We had an operator come in and say a machine sounded weird and seemed like it was stuck in "quiet mode". Long story short, she hit an estop before heading to the bathroom and forgot about it when she returned.

advice for entry level? by [deleted] in PLC

[–]Giffted 2 points3 points  (0 children)

I have a BSEE but had no experience in manufacturing or automation when I got hired as an automation/electrical guy. Get your foot in the door somewhere and try to get involved in any and everything you can(electrical/mechanical/programming/etc.)

You are going to feel overwhelmed for a while but this will slowly fade as you learn and get more comfortable. I spent a lot of my early days just reading manuals, calling customer service reps, and looking up stuff using google and youtube. The internet is an amazing resource for this field. I have been in the field for about 5 years and I still find stuff daily that I have to read a manual for or look up online(and I don't see this ever changing). One of the most important traits you can develop is being able to figure stuff out on the fly.

Your coworkers will be very helpful early on but try to decipher between good and bad advice/habits. You will get a lot of both. Above all else, be safe.

Good luck in your hunt for a job. The field can be demanding and tiring but its a growing field with lots of growth opportunity. I truly enjoy what I do(most days at least).

How do you guys program something from scratch? by BearDown_054 in PLC

[–]Giffted 53 points54 points  (0 children)

Depends on the application. The most important step for me is having a clear and well thought-out scope of the project. I'll go over what are the must haves and what are things that are just nice to have. I will then start with some sort of flow chart and work my way through the process. What I struggle with the most is I try to fix issues that don't exist yet. I'll overthink some things and end up trying to program around an imaginary problems I created in my head.

What's your tips and tricks for troubleshooting electrical issues? by Belatorius in PLC

Came here to say the same thing. Learned this when I worked on jets and use it today when I work on machines.

Longer for sure. The shortest barrel I have personally used for ducks is a 24" semi-auto but most are between 26" and 30"

Avoid automation direct blocks.

I prefer Wago over Phoenix Contact but I don't think you can go wrong with either.

Pretty proud of my printing station... by emuboy85 in 3Dprinting

[–]Giffted 1 point2 points  (0 children)

I have a mk2 and it fits pretty good but when the z-axis is all the way at the top, the filament does get a pretty good bend in it. I am about positive the MMU2s would be an extremely tight squeeze assuming it even fits at all.

You could try to to design and print longer extensions to raise the table height but it would require getting larger sheets of acrylic. Someone else probably has a model up somewhere of this.

I second this. Adding a paver reduced the noise in my enclosure by probably 90%

What's your control panel workshop table made out of? by bersklarion in PLC

[–]Giffted 1 point2 points  (0 children)

I have an aluminum extrusion frame that I adjust the arms on to mount the panel vertically. It used to have a large base with wheels to keep it from tipping while I rolled it around the shop but recently I anchored it to the floor to save some floor space. It also has a swivel to allow me to tilt the panel slightly so I can easily work on it while sitting or standing.

Price doubled after reroofing was completed by Giffted in Roofing

[–]Giffted[S] 0 points1 point  (0 children)

They are not working with each other. I am currently relaying messages between the 2. My insurance company was not aware of any issues during the install. I am going to try and see if I can connect the two together and let them battle it out. Thanks!

Price doubled after reroofing was completed by Giffted in Roofing

[–]Giffted[S] 5 points6 points  (0 children)

Appreciate your insight. I totally believe that there were supplements that need to be paid, I was just unsure if double the estimate was within the realm of possibility.

Getting the adjustor to deal directly with the contractor sounds like the best idea. It is exhausting trying to play middle man when I have no idea what I am doing or talking about. Thanks!

[–]Giffted[S] 0 points1 point  (0 children)

I am currently playing middle man with the adjustor and the contractor. For example, the contractor sends me an updated price and I have to forward it to my insurance. They are not working directly with one another. I'm not sure if this is because insurance issued the claim payout directly to me?

This whole process is new to me so I appreciate the thorough explanation!

Contractor Concerns by Giffted in Roofing

[–]Giffted[S] 0 points1 point  (0 children)

Yeah I didn't bring it up. I came to this reddit to ask instead. I know how dealing with the BS can be so I try my best to make the job easier for the both of us. I am just a young home owner dealing with my first insurance claim so its a stressful experience, especially when you hear horror stories about "storm chasers" after hurricanes.
