We use something like this
Off the top of my head, besides the laptop, I got:
Basic Electrical hand tools such as wire strippers and snips
Fluke 787 process meter
Fluke clamp on mA meter
Terminal Block Screwdriver by Klein
RS-485 to USB interface
RJ45s and crimper
Dewalt DCF680 Gyroscrew driver, do not get the "newer" 682, they removed the adjustable torque clutch
I am looking into a portable stand up type desk for my laptop so I don't have to use the closest transformer or balance it on a large pipe. Anyone have experience with these (Table Tote)?
Firstly, there's 3 well-known networking technologies where Modbus is used: RS232, RS485 (you'll hear the term Modbus/RTU for this) and Ethernet via TCP/IP (you'll hear the term Modbus/TCP for this) So find out what your devices use first. From there, you can buy a USB converters for all of the above if needed. If you're then looking to test polling slaves, I recommend QModMaster which supports all types of network interfaces
I had a co-worker, who flashed a card going this route: Hotel Wifi -> VPN -> VPN Land point -> Site ->Stratix switch -> Card. It was Go Live day, testing 9am and he thought he'd go ahead and flash that during breakfast. Sometime around 1pm it finally finished.
Tripp Lite Keyspan High-Speed USB to Serial Adapter, PC & Mac (USA-19HS) https://www.amazon.com/dp/B0000VYJRY/ref=cm_sw_r_cp_apa_yoGKBb3XE45Q6
This one works with windows drivers out of the box. USB cable is removable so you can make the cable as long as you want plus the length of the serial cable.
I strongly recommend Codesys (https://www.codesys.com/). It is a software used to program PLCs of various manufacturers. It’s free and has got a really great PLC simulator – it enables you to communicate with other devices over many popular protocols (Modbus TCP, Profinet, Ethernet/IP, OPC UA and some others).
Edit: As was stated before, Raspberry Pi might be a low budged alternative to a PLC. Codesys has a plugin that enables you to program Raspberry Pi, just as you would a normal PLC, if a simulator is not enough.
If it were me I'd purchase a small computer such as as HP NUC, then write a small application to write the joystick values to the plc. Microsoft has code examples for reading xbox buttons and joystick values http://www.codeproject.com/Articles/16983/Using-XNA-to-Access-an-Xbox-Joystick and you could use something like advanced hmi for the drivers to the plc advancedhmi.com
I bought one of these magnetic shelves. It works great in a pinch, just make sure not to get your phone or laptop too close to the magnets.
MobaXterm instead of Putty for SSH. It doesn't use the built-in windows shell which makes copy/paste much easier. It also comes with cygwin with linux tools and the ability to install more.
SumatraPDF (I also have Acrobat Pro, but SumatraPDF is MUCH faster to launch and use -- so I keep it as the default).
Much of the software available on ninite.com
I'm a bit confused, are you using it to create 3d renders for use on hmi screens? Shouldn't you be able to get the cad geometry from your design/engineer teams?
If you're just trying to make renders, and need a free tool I'd recommend using Blender3d. It has a fairly steep learning curve, but once you get a good workflow together it's capable of photorealistic renders and makes for an extra layer of polish if you can or want to invest the time. I have our designers export geometry to a surfaces model format like stl for rendering. My process is usually to apply textures from either substance painter or texture packs where simple materials don't have enough detail and then render using the princibled pbr shader.
It's also alot more capable at creating animated renders than fusion 360.
This or similar... Adjustable depth cut, spring it over the cable, once or twice around to cut the jacket, hold the lever over to rotate the blade, drag it off the cable to split the jacket
Control System Design Guide by George Ellis.
This book perfectly bridges together the theory you learn in school with the practical design knowledge you need in the field. Note that it is mostly about process and motion control, not PLCs.
Honestly though this reminds me of the Whirlpool factory I toured while taking a class in mechanical systems. Their system is very similar but at the end of the conveyor systems you have fork trucks.
I don't know where you're located now, but if you want to continue doing labview, you might need to move. If you want to expand into other software engineering roles, I recommend you take some classes about algorithms and data structions. A class like this would be a good place to start: https://www.udacity.com/course/data-structures-and-algorithms-in-python--ud513
12VDV huh?
Here's how you can do it with somewhat easy changes:
1) knock off Ardunio UNO:
From there go grab yourself a 12VDC Relay with a 5VDC coil.
You probably have a 12VDC power supply lying around the house...
Granted, how robust of a solution are you looking for here? A CLICK! PLC could also do the trick, but it is 60 dollars or so.
Looks to be terminals 12, 13 and 14 are used for a pot. Manual says 1 - 10k ohm, 2W max.
Something like this would most likely work:
10K OHM Linear Taper Rotary Potentiometer B10K Pot with Knob and 3-Pin JST-XH2.54 Connector Lead(Pack of 2) https://www.amazon.com/dp/B071X4DKV7/ref=cm_sw_r_cp_api_glt_fabc_0SVN60PZKC7W1FTYQEB0?_encoding=UTF8&psc=1
Edit: The pot within the link may NOT work for your application. I can’t seem to find details about it other than it’s ranged 0 to 10k ohms.
I use something similar. It's worked well for several years now. It came with a rubber pad so the laptop stays pretty secure.
If your on a budget or dont need anything high quality I've been using this for over a year and it hasn't let me down.
what do you mean by digital control? control of discrete variables can be simulated by many vendor software, some of them have free versions, like the rslogix rslinx and rsemulate500 combo. Maybe siemens have something like that too.
If you mean digital control, like https://www.amazon.com/-/es/M-Sami-Fadali/dp/0128144335 matlab can be useful, and labview, but those do cost money.
About how useful they are, those are tools, they are as useful as you know how to use them.
Honestly, the $5 yellow and black ones from HF are plenty IMO. They’re decently comfortable, and don’t scratch as easily as others I’ve been given at various sites (looking at you Uvex)
The toughest thing is keeping them clean and scratch-free so you’re not tempted to take them off while staring at a computer screen. I keep a bottle of lens cleaner with me and clean them every night at home/hotel. Rinse them before you clean them to make sure that you don’t grind dirt into them while cleaning them.
When they do ultimately get scratched/lost/broken, it only takes $5 for another. I tend to get 3-6 mos out of a pair.
The other side of keeping them scratch free is the rigid zipper case I picked up for them. It’s nice to be able to throw them in a toolbox and know they’ll be ready to go when you get onsite.
Yeah, I'm in the same boat. EE undergrad from a top 10 engineering university, but I graduated during the dot-bomb era of 2002. Up until relatively recently, I've only found software jobs. I only had one C++ class in undergrad, so I was woefully unprepared for software jobs. I've done mobile app dev and web dev. If you want to do mobile, you're either going to learn Swift and iOS libraries or Java and Android libs. Even if you do React Native you'll still need to learn one or both. Javascript or Typescript are solid choices for web development. Python is used almost everywhere, and at the very least is a good language to review concepts. For embedded systems or other low level stuff, you can't go wrong with C or C++.
I recommend going through all the common algorithms, data structures, and design patterns relevant to the field you're applying to. A free class like this is a solid way to get started: https://www.udacity.com/course/data-structures-and-algorithms-in-python--ud513
You can get a pretty small CNC roughly the size of an Ender 3: https://www.amazon.com/Genmitsu-3018-PRO-Control-Engraving-300x180x45mm/dp/B07P6K9BL3
I have no experience with this and can't say it is good or bad, but there are very small machines out there that you can buy or build from kits.
Depending on the model of the Stratix, you will likely need two power supplies. A 24v to power the switch and then a 48-52v power supply to power the POE ports. That will need to be sized based on the number of ports and the demand of the POE devices. I have done a few implementations like this for both the 5400 & 5700.
Another alternative is using an external injector. Typically we use the ones that Cognex sells with their cameras, like this [link] But I have also used a multi-port ones like this [link]
Virtualbox is free from oracle, and they're the ones that launched the whole VM concept(in the mainstream anyway) If you're a student, Linux distros are free, and noone cares if you pirate windows. If you're working professionally, IT dept should have some licenses. If you're working professionally for yourself, you can find licenses for operating systems to use in Virtual Machines on the cheap.
Cool, that description of a gateway device makes sense. The pointer to Kepware is appreciated too, I'll check it out after I've got my RS-485 network built out.
Turns out that they want a remarkable amount of money for their proprietary RS485 adapter, so I'll need to build myself some opto-isolators before I get started.
Yes you can. Node red is robust and embedded in many industrial hw and softy and you don’t even know it is. And latest release is even more powerful and build for professional development. See https://nodered.org/blog/2020/10/15/version-1-2-released
Although I don't know what hardware layer you're referring to, I feel like this is a good opportunity to insert a plug for my favorite serial capture program, RealTerm (http://realterm.sourceforge.net).
Linux running within windows.
https://docs.microsoft.com/en-us/windows/wsl/about
It uses the port that the config tool uses so you have to disable it whenever you want to use the tool.
My work has this in the back of the warehouse. Its a pretty basic setup. I would like some help with ideas or even better I was given a project that I have to program. For example you could simulate the inputs/outputs were actual components like a motor or start push button, etc... I thought it would be a good idea for someone to act as if they are the customer and have a machine or intended process that they want with different components already there and wired. You just need me the PLC programmer to make it happen. (I have no idea how this actually works in the real world.)
​
I have a basic knowledge on PLCs including the most important of instructions (XIC, XIO, ONS, etc...) I've taken a few course in college and a couple classes on udemy.com. I am the type of person that learns best buy doing it. I can read a ton, watch hours of video but the heart of it all doesn't quite click for me until I jack it up and then learn why and how I jacked up, then I fix it.
​
Some of the components:
​
the blue push buttons are normally opened mantained contact and the green push buttons are NO momentary contact.
the red push button is normally closed contact. I assume this is the hard wired stop button.
Groupy might work. I've never used it, but I really like the "Fences" product from Stardock.
Looks like you can try it free for 30-days and if you like it then it's only $5.
GoodNotes if said tablet is an iPad.
No idea on the Android front though. All of my other devices are Windows and Android, but GoodNotes fits my needs so well that I purchased an iPad Pro for my tablet.
Third vote for Swissgear. This one was recommended to me by older engineers when I started at my new company.
https://www.amazon.com/gp/product/B000VOC90Y?psc=1
Holds two laptops, notebooks, cables, misc equipment very easily with extra room. Still looks brand new after two years of moderate use.
I have this one: it’s a knockoff Swiss gear backpack but overall I am very happy with the amount of storage, pockets, it opens fully for TSA precheck (they say you don’t need to but I reduced my bag searches by 80% vs leaving it zipped up. I can fit so much crap in here. It has a built in usb that goes to the strap so you can plug in a big 20,000mah lithium battery into the pocket and charge stuff outside the backpack.
Would purchase again
Swissdigital Terabyte TSA-Friendly Water-Resistant Large Backpack, Business Laptop Backpack for Men with USB Charging Port/RFID Protection Big School Bookbag Fits up to 15.6" Travel Laptop Backpack https://www.amazon.com/dp/B07LBP8B9G/ref=cm_sw_r_cp_api_glt_fabc_CC43VVAMZ85D6VE4H0C5
For $30 you can get a Microsoft adapter, and won't have to worry about driver issues in the future. They sell these for the Surface tablets, so they'll have support for a good while into the future.
Use a DC-DC converter and get rid of the DC-AC-DC double conversion.
If the laptop uses a USB type C power brick, you could use something like this.
Or if you have a barrel jack on the laptop, you could use something like this
OF course, check the bottom of your laptop to see what voltage and amperage it consumes. Unless you're running some sort of huge gaming laptop, i highly doubt you're going to pull 240 watts at all. The power brick on one of my laptops says it can draw a max of 140 watts, but that's probably just initial inrush. It's rated output is only 45 watts.
I can lend a recommendation for this set. Wera - 5347108001 347108 Kraftform Kompakt VDE 60 i/62 i/68 i/18 Insulated Blade Set https://www.amazon.com/dp/B01D9I90GY/ref=cm_sw_r_cp_api_glt_fabc_3MA18N4QHMSCDP9Z6CZ7?_encoding=UTF8&psc=1
Owned one for a few years and love it. Even has pozidrive for European contractors.
If it doesn't have the one you want you can get it separately and add it to the set (the loops can hold two smaller bits). I had to add Robertson bits, and more smaller slotted. It already has a few hex bits.
It fits in my back pocket when I'm working, and a small pouch in my laptop bag when I don't need it.
It's funny to see this post pop up, when I just finished ordering equipment for this five minutes ago.
UPS systems are a pain in the ass. You have to change the batteries every two years, and after about four years the manufacturer will switch battery styles and you can't get them any more, or the electronics go bad and either way you have to buy a new one. I'd stick with batteries and just use better quality equipment.
I have an application where I have to supply 24VDC at 60amps for five minutes in the event of a power failure, and I use this charger, which is bulletproof. I have two Optima blue top batteries to make sure I have plenty of capacity. The whole setup costs less than $1200 by the time I buy a mounting bracket and box, and compared to a UPS with the same capacity that's dirt cheap.
For these kind of applications you want to stick to marine grade components. They operate in a harsher environment than most industrial equipment, and they won't cost a fortune.
The brother desktop USB I have is about 100 and the hardened portable is 150. Though you can get both for as low as $40. Mine was more expensive bc it has special cutting function. Though anymore I disable the cutter and use scissors. Bothh are portable in that they have battery packs though. I've read that the hardened portable can also print CSV files, if so then I'd just go with that one. I like that they're cartridges are interchangeable and shrink markers are about $1.50 a foot vs Brady which are $6 to $8 a foot. That's where the big $$ savings is. On one panel I save $250 in labels. I don't notice any more or less smearing between the Brady or Brother labels either. It's worth noting my labels are going in a purged climate controlled panel. For labels that are gonna be in harsh environments you would want a better printer. Though in your case you don't have that option.
https://www.amazon.com/dp/B00KHVE28S/ref=cm_sw_r_cp_apa_glt_fabc_3DFYWRWAA5RNA7DR20VT?_encoding=UTF8&psc=1 is the one I'm buying next.
https://www.amazon.com/dp/B00JHME7W4/ref=cm_sw_r_cp_apa_glt_fabc_2VB5F2V3CQGBMTBAYJPF Is the desktop one I use now. There are cheaper versions of both models. Look for printers that use the tZE labels.
I have a meter that's an older version of that, and it works fine. My one big gripe with it has been fixed on this model, which was it has a button to switch between AC and DC voltage measurement, and it defaults to AC, which I always forget about.
Having said that, for that kind of money you can get a Fluke, and I definitely prefer Fluke to the Southwire.
Can you use a breakout board like this?
How do you like the chair? I assume it is this one:
LIFE 2 GO Portable Telescoping Stool (Gray) https://www.amazon.com/dp/B0842845Y2/ref=cm_sw_r_cp_api_glt_fabc_Wd6cGbHQYRQZ0?_encoding=UTF8&psc=1
https://www.amazon.com/dp/0976625946/ref=rdr_ext_sb_ti_hist_1
That's the best book I've found but it still isn't what I'd call excellent. It's decent to good.
I don't think books are useful to learn about PLC programming.
I came here to suggest this. I prefer the Knipex variety, but there are several options out there.
Also a steady hand and a fresh razor blade is [probably what I use most often personally.
Have you ever tried using a cable scoring tool? I started using it when I was using a bunch of marine cable for a project and I’ve been using it since! A bit safer than running a razor blade, which we all do, and I’ll bet we have matching scars 😂
Seatek SA200SK Strip-All Cable & Wire Stripper with Wire Stripper, Utility Knife & A-201 Adapter https://www.amazon.com/dp/B000KL4R62/ref=cm_sw_r_cp_api_glc_fabc_up7.Fb4XVK719?_encoding=UTF8&psc=1
Something like this makes life easy. All the jumpers are included and you can use 2 digital outs for foreword and reverse.

Thanks for the reply!
I've been looking into this one which is fairly similar:

Separate compartment keeps laptop protected from other tools.
I originally had a table like you posted, but didn’t like that I couldn’t get my legs underneath it when sitting in a chair like you posted.
Now I use this. Much larger, probably tough to fly with unless you use like a golf club bag length travel case, but for driving trips it does the job well.
PORTAL Outdoor Folding Portable... https://www.amazon.com/dp/B07ZS892BT?ref=ppx_pop_mob_ap_share
If all you want to do is have a pot to adjust the signal and a meter to show the current value see https://smile.amazon.com/dp/B071NLGP6L/ref=cm_sw_r_cp_apa_i_QSCmFb2WQJJ38
Note that it requires a 24 volt DC power supply.
My work got us these and they are fantastic!
As far as "disposable" cheap glasses go,these are by far the best I've ever used.
I was given a pair at a customer site once, and bought a whole box of them as soon as I got home. Where I'm at now I've switched the whole facility over to them, and everyone likes them much better than the previous clear frame glasses we were using. The clarity of the lenses is just a lot better than most cheap glasses, and I often catch myself sitting in my office wearing them because I forget I have them on. You can get them a lot cheaper at industrial supply places if you buy a box of 10 (less than $4/ea).
I have one of those and it works okay for quick troubleshooting or commissioning jobs. Flimsy, but its portable and gets the job done.
I also have one of these awesome old Stanley project centers for when I'm gonna be there for awhile.
Veto Pro Pac XLT Laptop-Tool Bag is the bag I use at work. I load all my commonly used tools, cables and laptop.
https://www.youtube.com/user/plcprofessor/videos
this guy is really great, hope this helps you. Also i bought this Book and found it to help me a lot.
http://www.amazon.com/Programmable-Logic-Controllers-Emphasis-Application/dp/097662592X
Literally the best book you can buy for the money. This will cover everything you need to know to at least get you started.
Best experience would be getting your hands on the PLC. Buy a click or velocio PLC. Super cheap and free software. I suggest the click though because it is better in terms of software and voltage control (5-12 VDC on the Velocio compared to a relay output, 24VDC input on the click)
I was sort of in the same boat as you. My company jumped into PLC's last year as an experiment. We began with the CompactLogix series of units. I volunteered because I was a technician at the time gunning for an engineering spot. I wound up completing the project and getting hired on as engineer. Now I've got like 3 more PLC projects lined up.
http://plcs.net/ has been the best resource for me as well as the various PDF's available from AB on the hardware you're using.
This book might be a good starter: http://www.amazon.com/Instant-PLC-Programming-RSLogix-5000/dp/1849698449/ref=sr_1_23?ie=UTF8&qid=1423082293&sr=8-23&keywords=allen+bradley
I gave it a 2 star rating because I'd messed with RSLogix before and knew most of the basics in that book. The overview implied a lot more depth than was actually provided. If you PM me your address, I'll ship it off to you for free.
Best of luck! It's a bit overwhelming at first, but once you get your hands on the software and get to start messing around with the logic, it starts making a lot more sense. If you have a mind for programming, you'll be fine :)
I should buy extra of these books to hand out at customers site: https://www.amazon.com/dp/B006XZZTHA/?_encoding=UTF8&pd_rd_w=egctl&content-id=amzn1.sym.cbade754-6bb5-483b-a66b-155fcb6f6105&pf_rd_p=cbade754-6bb5-483b-a66b-155fcb6f6105&pf_rd_r=DBHWJBR584Y5P17F45RW&pd_rd_wg=ONeID&pd_rd_r=6...

Aux port is a DB15 serial port, RS232 is the standard, modbus rtu or something similar is likely the protocol.
Piggybacking on your comment share this
There is an awesome book called the technicians guide to troubleshooting. which covers many troubleshooting techniques. It breaks down techniques that experienced individuals use and they may not even realize they are doing.
Just found this on amazon. They have 0-10 or 4-20. https://www.amazon.com/Environmental-Monitoring-Transmitter-Detector-30-120DB/dp/B083Q6VG19/ref=asc\_df\_B09NNJ4BNM/?tag=hyprod-20&linkCode=df0&hvadid=632919759294&hvpos=&hvnetw=g&hvrand=10720128189879740209&hvpone=&hvp...

Someone had posted that they used a sheet music stand. It looked pretty slick.
Git is the version control system used by almost everyone for everything. It has a greater than 80% global market share and over 100 million users and there is a reason for that. This sub has many posts talking about how to make it work okay for Rockwell projects (as good or better than AssetCentre while being faster and free).

Don't daisy chain, use commoning strip on those terminals.
Then you will also only need 2 terminals for each of these things you're making.. wait, what are you doing?

I ran into status vs command when creating a MQTT<->OPC bridge. All my messages started looping between protocols.
The way I understand it is that a command is something actionable by a device and a status is the data points of interest for collection or triggering a command.
Is that what you are talking about?

I always end up using foxit. I've turned off auto update on the apps I get with ninite and have a scheduled task to run the ninite exe. That way it's always up to date and I don't have to press any buttons.
Friend, consider this:
Why get a brighter screen when you can get a darker sky?
But wouldnt these do CAT6 terminations? I thought cat5/6 was same 8p8c connector?:
In both technical colleges I was at we used these books along side Thelearningpit.com and a copy of LogixPro which uses bit level addressing like older PLCs used to use. I am a strong believer in that if you are able to lay a good foundation of how they work they are better off. Without a good foundation the rest of a house would crumble.
If your adapter doesn't have an instructions manual or pinout. Probably is a half duplex adapter. And uses only 2 pins
If you compare to this you will she that only the center pins (4 & 5) are used .
Cut a prebuilt ethernet cable (doesn't matter if is TIA 568A or 568B) and use the blue pair (blue, white/blue)
Some IT systems won’t let an executable run, so in some cases you can’t use Bitlocker or third party software to unencrypt. I’ve used Datashur keypad USB and that is great to overcome those issues. https://www.amazon.com/iStorage-datAshur-256-bit-secure-encrypted/dp/B0061DBZ2C
Younwill need the CQM1-CIF02 cable and you will also need an RS232 to USB adapter. Most any brand will do but the Omron CS1W-CIF31 is expensive but basically bulletproof.

Our distributor samples them to us, but you can buy them too. Handles NPN, PNP, and has easy spring terminals for flying leads. I made a short M12 to M8 adapter for mine as well.
Also just a random tip - if you are using PT100s in thermal wells, smear them with some sort of heat sink paste, as air is a terrible conductor of heat and if there’s even a small air gap between the RTD and the well, you will get slow, inaccurate readings.
I bought that thing a decade ago, but it's like this one. I don't know about the quality of this one though.

I also carry breakout boards.
It was a book... A lot of good nuggets in it based on behavioral research.

Not exactly for pants but if you're in the heat, I just ordered this fan to wear on my belt and blow air on me. Haven't received it yet but it looks promising. https://www.amazon.com/Capacity-Operated-Necklace-Hands-free-Gardening/dp/B088R8GTVQ/
We have a bunch of them in the field :(
and the PLC families we use only have a single RS-485 Bus - this looks somewhat promising.

Tha book is good, it covers what you need to start. There is another, more general book on PLC's by the same author, and it's worth it as well. Start with this book though.
Also, SolisPLC has some courses that are an okay start. Good luck, you got this.
You can buy a loop current generator cheap on Amazon. Tim Wilborne recommends a model but I don't remember which one.
Here is an example: https://www.amazon.com/Generator-DROK-Adjustable-Transmitter-Simulation/dp/B071NLGP6L
All of the good Hall-effect type current meters that I know of are pretty spendy.
This one isn't Hall-effect but it's pretty handy, with reasonable sensitivity "Flir TA72 Universal Flexible Current Probe" Just plug it into any volt meter.
Altek if your looking for over built but low on bells and whistles.

I concur on the learn as you go suggestions. I would think that demand for programmers is such that with electrical experience if you apply for a programming or controls tech/engineer job and show a high interest in learning programming that you could get hired.
I am a mechanical engineer by degree with experience designing automation, 0 experience previously with programming and was recruited for a programming job last year. Caught on pretty quick and I love it. We use all AB compact/control logix.
I mostly learned from the following sources:
Udemy courses offered by Vlad from SolisPLC, he often has deals to get the course for like. $15. This is where I started. From there it's been YouTube, books and coworkers. I would also recommend finding a place to work that has at least a few people that have extensive experience to learn from, this will save a lot of frustration..
