PLC vs Industrial Open-Source Controller (Arduino-Compatible) Productivity Open - AutomationDirect

[@whickervision742]

This is great that it has the necessary certifications (especially UL) to exist on a DIN Rail without an inspector flagging it. I do wish there was a watchdog library to enforce a maximum time in the loop section. Too many will use endless while-loops waiting on a signal and learn the hard way. But for those who know good practices, this is a very freeing and empowering product.

[@automationdirect]

Thanks for the comment whickevision. Having a certified Arduino that is expandable is definitely a game changer for Arduino in the Industrial world. There are some example codes for a watchdog in the Arduino IDE and there are plenty of Watchdog examples on github and other Arduino code repositories. The effectiveness of these are still dependent of the programmers implementation.

[@adamcummick]

We actually have a watchdog feature built-in to the P1AM-100 for this exact reason. Check out more information on the CPU here: facts-engineering.github.io/modules/P1AM-100/P1AM-100.html

[@caffeinatedinsanity2324]

The SAMD21 comes with an internal watchdog timer. Even the atmega328p (arduono uno/nano) has one. Yet of course you need to program it and tell him if you want to cause a restart, an interrupt, both, etc... I'm very sure that the development team will come up with a library to set up the watchdog timer and events it can generate. Right now I got nothing but the SAMD21 datasheet to design a quick library and have nothing to use for testing.

[@whickervision742]

Ok. So there is a watchdog to "pet", or else the output modules will shut off. Thanks for confirming, see the GitHub example links above.

[@trandyz2521]

I still prefer the Arduino Industrial standard, they can withstand very low and very high temperature, cheaper, I can automate my process anytime, the only problem is modifying codes in real time, I hope Arduino is upgraded to perform that too

[@automationdirect]

@ Trandyz, We are glad you enjoyed our video. Arduino and Raspberry pi products are very popular options for control projects. Hopefully developers will continue to add more options. Make sure to check out our other videos www.automationdirect.com/videos?KOjPn9LVcjI&VideoTeamComment

[@levvayner4509]

I see the video is made for the PLC audience. Just wanted to let you know there are many ways to make applications configurable at runtime, meaning you can control any part of your plc without re-compiling. You can also use an ESP32 or similar to extend your Arduino type PLC to be an IoT device. It can report to your cloud backend, and receive control messages from an automated and centralized system.

[@automationdirect]

Thanks for the info!

[@chuck5761]

Please don't only keep a copy of the Arduino project saved "locally". The HUGE advantage of the arduino is that you have access to internet based source code repositories like github. Keep the project there. This is probably a practice that should be adopted even for PLC development, because there's no downloading the code from a PLC that's been cooked in a fire.

[@automationdirect]

Thanks Chuck. That is a good practice.

[@petermorrow3565]

Doesn't that leave copies of your codes in someone else's hands? Not hard to hack into people's saved projects these days.

[@VictorF0326]

Naw. 1. Internet connections allow these devices to be connected to everyone else. Unless there is very good security control its much better off just keeping the arduino code locally. There was a cyber attack last year on Solarwinds that affected thousands of PLCs without being detected. One of the companies I also worked with got hit and their database was hacked. All the technician laptops were all taken away since it could've been infected by a Russian program. 2. In the medical factory industry, its standard to take backups of the code to store in controlled locations as required by the FDA since the code can contain recipes and more importantly can contain audit trails (logs of responsibility, who pressed what button and when) depending on how old the PLC is. So they have regular backup procedures for them one way or another. 3. Typically the PLC/Arduino only have 1 or 2 ethernet adapters which needs to be specifically used for the PLC/Device network. It's usually challenging to incorporate a NATR module or a router just for this purpose as it adds a level of complexity and vulnerability. 4. The term save the code On-Site is mentioned. On-site does mean local, but as mentioned before there is strict control of the backups of these programs which is saved to the enterprise network 'on-site' or global. The purpose of the control practice is to not lose the program even if the building burns down. 5. Having the internet not necessarily is always good and it's not really a huge advantage other than sending report data in most industries. Perhaps it can be set up for automatic firmware updates, but this risks breaking something and is frowned upon in a zero risk tolerance environment. In addition, depending on the set up the PLCs are capable of sending data directly to the enterprise network for that matter depending on the set up. There's simply no use for this 'local' copy since it's very easy to lose. I've had OEM vendors lose a copy of even a PLC code and because SIEMENS doesn't allow code to be pulled from the system ,like it is possible on Rockwell or some other PLCs, we're stuck with a PLC that can never be edited. This is much more easier to happen to Arduinos. That all being said, we have a company only enterprise GIT network for some of the backup/recovery systems just as a tertiary backup since losing code probably means you won't be working there anymore.

[@dirtydangler99]

When i took my first electrical engineering job knowing Java, C++, and objective C. I was very surprised to find how bulky PLC’s are. Felt like I travelled back in time. They seem to be sticking around because the wide variety of people who know how to use them. Seems like there is a large product switch coming, once the new grads come out with C++ expertise, and the older guys retire. That being said, PLC’s are reliable and run forever.

I've always used PLCs in Chemical Research and I enjoyed the reliability. I was controlling massive pressures of H2 like 3000psi, and temperature controls up to 800F, while pumping oil into a mixture of that pressure with the H2 and high temps. We had a huge control panel of PLCs maybe 6' wide and 8' tall controlling 8 different reactors like this. We concerted pure oil from many different sources into pollution free gas, airplane fuel, and diesel. 0ppm NO2 and 0ppm SO2, and 0ppm aromatics (benzene rings). There was a time when a tiny stainless weld gave way during a pressure check of the system and shot a metal rod inches from my face at bullet speed. The room filled with H2 and all the computers and GCs were in the room so I knew there were open electronics and I was glad to have that HUGE red push button to shut EVERYTHING down as I ran away from the reactor and into the hallway screaming LOL. That being said. There are many libraries easily used for many arduino tasks. I just wouldn't trust one to operate Highly dangerous chemical reactions. I personally use the Arduino and Pi often. I have also used SCAD to operate reactors. That code in Visual Basic is easy to set up a controlled temp and pressure and flow but still, basically PLCs. I don't think they would ever depend on an arduino. I worked for Chevron, Shell, and Dow Chemical. PLCs will always be depended on. No cost savings interested in when safety is a concern. I like your input.

[@jefferysprings4314]

for those of you that may be unfamiliar with arduino and c programming there is software called xod that has a bunch of libraries and conditional controllers that make programming the arduino so much easier and will convert your project into c so you can copy and paste into the arduino ide to run. the website for it is xod.io and youtube has videos that will help with getting you started on how to use it

PLCs are for industrial control. Arduino compatible MPUs can do anything and are everywhere. I have done 1 mhz control, a usb to ttl converter, a wifi robot, mesh networking, xmass lights, wifi garage door opener, irrigation system, you name it. They are open source hardware boards and software. I'm a c programmer interested in electronics and arduinos are a gift from heaven, since the learning curve is shallow, so they are fun. One time I was mowing my grass and two people stopped me to ask me questions about arduino. It's that popular.

Thank you for your comment. Both platforms are very useful. Understanding each platforms pros and cons, will help you evaluate which is best for your system.

[@zygmuntkrukowski3789]

I've found working with both professionally is that PLCprogramming is significantly visual based so is more intuitive.Arduino brings extreme low cost but has a steeper learning curve since it's all text based and you have to determine it's limitations and conflicts and correct. A lot of fun with both and consider them Legos or an erector set for adults

[@caffeinatedinsanity2324]

I would give the Arduino a deserving spot for when you need to subdivide your tasks and give them to multiple controllers led by a "brain" (that would be the PLC). Since Arduinos are likely to be less expensive, you can use it as a worker who only reaponds back to the foreman, aka the PLC. You can interrogate the foreman for info on the process (via online diagnostics). Heck I wonder if you couldn't make your own servo drive out of it. Stuff like that where you don't typically interrogate the device itself. It's never going to replace the PLC, but it has a niche in terms of purpose. And of course, there's a matter of preferences.

[@caffeinatedinsanity2324]

Also the fact that an Arduino-like CPU costs 45$ (which is very, very inexpensive for an industrial CPU) means that you can much more easily mount a distributed system which often involves hierarchical controllers, where some aren't as important to monitor. Now of course networking is going to be more difficult. But the open-source community won't take long to catch up and create libraries to fulfill these spots

[@camfocus8888]

OMG! The basic difference is plc is a time line scrip language so read the code inside the chip is same cold in programming. Also it is real time processing which is more reliable than mcu even the mcu is already very reliable and because it is time line scripts there’s almost no mistake room. But it is 360 all down side than any object language to programming especially in a large project and that’s why only little still in factory application.

[@automationdirect]

Thanks for the comment.

[@tri-pakmachinery6919]

Great explanation! As an OEM, the inherent IP security, complete customization and extremely low cost of Arduino is very appealing. But we went with PLCs because of the reputation of reliability, less steep learning curve, data mgmt, and higher current switching capability out of the box.

I worked with PLC’s before Arduino was ever mentioned for the first time and never used one. In today’s industrial espionage world, which is simpler to protect from hackers, the PLC’s or the Arduino platforms?

[@automationdirect]

Any security protocol will include factors both internal and external to any controller. For the Arduino, security will depend on the measures that are programmed and implemented by the user. PLCs do offer embedded security (depending on the platform) like password protection, ping disable, session-based communication, etc. However, the controller’s internal security should be just part of a multi-layer security approach. Check out this article for more: www.controleng.com/articles/cybersecurity-centered-systems-and-fundamentals/

[@glennedgar5057]

I use Click PLC's to turn on Relays controlled by a raspberry pi brains. Many times I need to interface to a device such as a one-wire temperature sensor, i2c device or a device requiring special analog processing. The Arduino option allows the uses of industrial hardware to be used, instead of rolling your own. This is important as interfacing stuff like din rails and terminal blocks can be used. A long time ago, I developed an interpreter for a cortex m3 device, that was used to control DSL links between a gas station and pumps. The interpreter read its program from an sd card. I think this would be a good solution for reprogramming devices in the field.

[@automationdirect]

Thanks for the comment Glenn

[@Experts_top_5]

so, can i use Arduino as much reliably as PLCs keeping the safety at the top? so why industrialists prefers PLCs over an ARDUINO ?, they are really cheaper though....

[@automationdirect]

Hritik, The industry prefers PLCs as they embedded routines to run in an industrial environment, whereas with an Arduino these routines would have to be made by the programmer in Arduino. Examples of this is Hardware and software watchdogs, Hardware configurations, and other quick to setup macros that are present in PLCs. Arduino compatible controllers have their place in the industrial world but PLCs do make it quicker and more reliable for more common users.

[@jonathanstodden6029]

I was first wondering about counting using an encoder module since usually you don't want to use interrupts and slow down your code, especially if you have time critical coding and an encoder that has like 3000+ pulses per rev. However, in the meantime, I was playing with another microcontroller, the stm32 blue pill. And it has an explicitly defined "encoder interface" which basically is an external clock input that has direction control. Now I looked into the SAMD21's datasheet and there is indeed the possibility of controlling the counter's direction based on events. A little bit more complex to set up, but still possible. (Page 682 of the SAMD21 datasheet) The Atmega328 (arduino uno) does not offer direction control. You can only increment the counter.
