The PLC (Programmable Logic Controller) has been and still is the basic component of the industrial automation world. PLCs are usually pretty expensive pieces of hardware, which led many people who know micro-controllers to come up with their own ideas to implement similar functionality.
Arduino is a kind of universal programmable controller, although it is only the “core” and in any case it has been built for general applications; with a little of external hardware (essentially interfaces capable of transferring signals from sensors and to actuators, reducing the EMI which may damage the microcontroller) and an appropriate software may, however, become something very similar to a PLC. For output you can use Arduino Relay modules. For input you can use varying Arduino sensors of build your own adapter for some industrial sensors.
Arduino as a programmable logic controller (PLC) tutorial we will explain how to “convert” our Arduino board in a PLC-like controller. There are several ways to turn Arduino into a Programmable Logic Controller, and Arduino as a programmable logic controller (PLC) tutorial presents two: Ladder Logic for PIC and AVR software and ladder.h Generator for LDmicro → Arduino. Also OpenPLC project has a OpenPLC Ladder Editor that can generate code for a standard arduino from a ladder diagram.
In some applications PLCs are more used as IO interfaces for SCADA systems more than doing the controlling. If you want to make Arduino board to look like PLC from SCADA point of view, you can put in software that make it to communicate with MODBUS or other suitable SCADA protocol. One easy way to experiment is to try SCADA for Arduino that includes both Arduino software and SCADA software. I tried it and you can read my experiences with it at Experimenting with SCADA for Arduino posting.
If you are worried if your Arduino based rat’s nest would survive in industrial environment or would be accepted by industrial control people, it is a good idea to to consider available Arduino compatible products designed for industrial control applications. There are now several commercial products built for Arduino PLC applications:
CONTROLLINO advertises to be first software Open-Source PLC. It is ARDUINO compatible.It started as Kickstarter project, but is now available directly from manufacturer web site. It advertises to be designed to control your Internet of Things and be CE & UL certificated. For more details check the video ARDUINO + PLC = CONTROLLINO
Industruino is an Arduino compatible industrial controller. Industruino is a fully featured Arduino Leonardo compatible board housed in a DIN-rail mountable case + prototyping area + onboard LCD + membrane panel. With this product you will be able to permanently install your Arduino application to industrial. Industruino is a pre-built solution offering a range of industrial voltage level I/O. All controlled with the ease of Arduino coding.

DIN Rails For… Everything
https://hackaday.com/2021/05/11/din-rails-for-everything/
For example, in some businesses DIN rails are a part of everyday life. But for a long time, they were not very common in hobby electronics. Although rails are cheap, boxes for rails aren’t always easy or cheap to obtain, but 3D printing offers a solution for that.
So while the industrial world has been using these handy rails for decades, we are starting to see hobby projects incorporate them more often and people like [Makers Mashup] are discovering them and finding ways to use them in projects and demonstrating them
The DIN rail originated in Germany around 1928, with modern versions dating from the 1950s and in some environments they are everywhere. DIN, by the way, is an acronym for the originating German standards organization Deutsches Institut für Normung, but the rails also meet IEC and EN standards, today.

THE 4-20 MA CURRENT LOOP
https://hackaday.com/2017/07/19/the-4-20-ma-current-loop/
The I/O capabilities built into most microcontrollers make it easy to measure the analog world. Say you want to build a data logger for temperature. All you need to do is get some kind of sensor that has a linear voltage output that represents the temperature range you need to monitor — zero to five volts representing 0° to 100°C, perhaps. Hook the sensor up to and analog input, whip up a little code, and you’re done. Easy stuff.
Now put a twist on it: you need to mount the sensor far from the microcontroller. The longer your wires, the bigger the voltage drop will be, until eventually your five-volt swing representing a 100° range is more like a one-volt swing. Plus your long sensor leads will act like a nice antenna to pick up all kinds of noise that’ll make digging a usable voltage signal off the line all the harder.
Luckily, industrial process engineers figured out how to deal with these problems a long time ago by using current loops for sensing and control. The most common standard is the 4-mA-to-20-mA current loop

How Electrical Control Panel Works | PLC Control Panel Basics | Electrical Panel Components
https://www.youtube.com/watch?v=QV8mxq1umEQ
Behind the scenes of every factory, there are lots of electrical panels that make the process work properly. These electrical panels can be distributed throughout the process or located in a special room like a control room or electrical room.
In this video, we will talk about one of the most important industrial electrical panels, the “Electrical Control Panel.”
First, we’ll quickly check the electrical panel enclosure and the nonelectrical devices we should install inside, such as DIN rails and wiring ducts.
Second, we’ll check out the electrical panel components step-by-step. We specifically talk about the PLC control panels.
We talk about, Miniature Circuit Breaker or MCBs and how we distribute the power between electrical panel components using them, and how MCBs protect our electrical devices against short circuit faults.
Throughout this video, you’ll learn about electrical panel wiring. How we use power supplies, ordinary terminal blocks, terminal strip jumpers, fuse terminal blocks, MCBs, and so on to up and run our PLC control panel.
In the end, when all of the components of our control panel have been installed, wired up, and we turned on our main circuit breaker to power it on, I’ll give you an actual practical example of how to connect a sensor to our PLC and use it in an industrial process.

Why we use Relay in PLC Applications | Relay Wiring Diagram | Types of Relay-SPST, SPDT, DPST, DPDT
https://www.youtube.com/watch?v=NwxSsoR4OHA
Have you ever thought about “why we use relays” or “How to use them”?
As you may know, the relays in the industry are fallen into two main categories. The Solid-State Relays or SSRs and Electromechanical relays or EMRs (They are also called mechanical relay or contact relay).
Of course, if you’re an electrician you may face some other types of relays such as safety relays, Power Protection relays, and so on.
You may see Power relays installed on medium voltage panels and they are a type of protection device for power systems. They more resemble a controller than a relay! So, we decided to talk about them in detail in another video.
In this video, you’ll first get to know about Electromechanical relays that are the most used types of relays.
Then, you’ll see how electric relays work and learn about the relay wiring diagram. After all, we’ll answer some questions: What do we use a relay for? How to wire a relay?
We also talk about the combination of normally open and normally closed contacts of the relays which will shape different types of mechanical relays.

The Role of PLCs in Industrial Control and Test and Measurement

Programmable logic controllers (PLCs) are industrial computers that:
Monitor and control industrial-automation applications
Execute tasks related to test and measurement operations
Perform process-type functions (including those related to HVAC systems) beyond the scope of this article.
PLCs receive data from sensors and input devices, process the data to make logic-based decisions, and output control instructions to mechanical or electrical systems. They are a type of embedded system that combines computer processor and memory with input-output (IO) devices — much like the hardwired relay-based logic as well as PC-based logic with which they compete.
In terms of physical form, PLCs today can be anything from a very simple computer having an integrated chip (IC) morphology to a large rack-mounted collection of controller subcomponents housed in multiple chassis. Simpler microcontroller-based PLCs or those taking the form of system on a chip (SoC) PLCs can be extremely reliable and operate off of very modest power input. In contrast, the most complex PLCs blur the boundaries between what constitutes a PLC and general-purpose computers for real-time industrial control … although reliability and real-time performance are still emphasized for the former.
Originally, PLCs were meant to directly replace hard-wired control logic based on relays and drum sequencers. These early PLCs only had to perform basic operations by transforming inputs into outputs. Any machine tasks necessitating proportional-integral-derivative (PID) control were outsourced to attached analog electronics. Now PID controls and even more sophisticated operations are a standard part of PLC instruction sets.
In fact, the functions expected of PLCs have proliferated over time — so that today, many PLCs are quite sophisticated and able to execute complicated and adaptive routines. The ever-increasing power and shrinking size of semiconductor chips (thanks to Moore’s law) have enabled unprecedented intelligence from smaller controllers. This trend is continuing with integrated support of motion control, vision systems, and communication protocols. At the other end of the PLC size spectrum, some programmable automation controllers (PACs) integrate a PLC with a PC to replace PLCs and proprietary control systems (run off proprietary programming languages) for certain applications. More PLCs today are also being integrated into human-machine interfaces (HMIs).

Takana ovat ne ajat, kun Raspberry Pi tunnettiin lähinnä rakentelijoiden hauskana edullisena korttina. Yhä useammin sen ominaisuudet riittävät teollisuuden laitteisiin. Nyt Sfera Labs on rakentanut Raspberry Pi -ohjainpiirillä teollisuuteen I/O-moduulin.
RP2040-ohjain esiteltiin vuosi sitten ja se on ollut tervetullut lisä Raspberry Pi -korttien rinnalle. Sfera Labsin Iono -perheen uusin moduuli yhdistää monipuolisen digitaalisen käyttöliittymän, paremman laskentasuorituskyvyn ja helppokäyttöisyyden erilaisia digitaalisia ja analogisia tulo- ja lähtölinjoihin.
Teollisuuden digitaalisiin I/O-sovelluksiin suunnattu moduuli sisältää RP2040-ohjaimen, 16 digitaalista 24 V I/O-linjaa, RS-485-sarjaliitännän ja laajan valikoiman 12-24 V virtalähdetuloa. Kompakti DIN-kiskokotelo tukee nopeaa ja helppoa asennusta sähkökaappiin ja rajoittuneisiin automaation ohjausjärjestelmiin.
Tehokkaan RP2040-ohjaimen monimutkainen sulautettu logiikka voidaan kehittää ohjelmistossa ohjaamaan lähtökytkimiä jopa 200 kHz:n taajuudella push-pull-tilassa. Jokainen lähtö kestää 640 mA:n kuormavirtaa, siinä on avoimen kuorman tunnistus ja se on suojattu oikosululta, ylivirralta ja käänteisvirralta. Tulot ovat myös erittäin hyvin suojattuja ja niissä on johdinkatkosten havaitseminen.
Ohjausohjelmistokehitys onnistuu MicroPythonilla ja C/C++-kielillä.

Arduino Launches IP40-Rated Edge Control Enclosure Kit with On-Board LCD User Interface
https://www.hackster.io/news/arduino-launches-ip40-rated-edge-control-enclosure-kit-with-on-board-lcd-user-interface-8e12392a7576
New case kit is designed for local status reporting on its integrated display, protection from dust and impact, and DIN rail mounting.
Arduino has launched a kit designed to make its Edge Control board a little more robust, offering an IP40-rated enclosure with on-board LCD and button interface for quick status updates: the Arduino Edge Control Enclosure Kit.
Arduino unveiled the Edge Control last year, aiming the board at agricultural automation and other industrial control tasks. The heart of the Edge Control is a Nordic Semiconductor nRF52840 system-on-chip powered by an Arm Cortex-M4F CPU running at 64MHz with 1MB of on-board flash, 2MB of external QSPI flash, and Bluetooth connectivity.
As an industrial control device, power to the Edge Control board is supplied through a 12V input — and given its focus on agriculture, a solar system is recommended with a 5Ah battery offering a 34-month operational lifespan between charges, depending on connected devices and duty cycle.
Arduino’s enclosure design comes in. Designed with IP40 certification for dust ingress, but not for weatherproofing, Arduino’s bespoke case design offers integrated DIN rail mount support for ease of mounting.
The kit isn’t just a simple housing, however: The Edge Control Enclosure Kit also includes a two-row 16-character LCD display with white backlight, linked to a push button designed to scroll through status reports and sensor readings.
“It can be customized by users to instantly visualize sensor data, such as weather conditions and soil parameters,” Arduino explains. “Different data can be displayed at every push of the button, on the spot and in real time, without requiring connectivity.”
The kit is now available through the Arduino Store, priced at $54 including the LCD interface; the Edge Control board is priced at $228.90, with support for MKR-compatible radio add-on modules starting at $37 for extended connectivity options.

PLC Ladder Logic on an Arduino: Introduction to OpenPLC
https://control.com/technical-articles/plc-ladder-logic-on-an-arduino-introduction-to-openplc/
Build a low-cost PLC using the Arduino Uno and the open-source industrial controls software, OpenPLC, to learn how to program with ladder logic, beginning with your first OpenPLC project: Hello World.
Versions of OpenPLC
The technical development path of the OpenPLC platform consisted of two basic versions of the open-source programming language toolchain, version 1.0 and version 1.2b. Version 1.0 provides a simulator for testing LD programs. The software version can run ST code on a target Microchip ATMEGA328 8bit microcontroller. Version 1.0 provides a runtime feature that allows installing C-code and displaying the Microchip-based PLC input/output devices running on the ATMEGA328 microcontroller. Figure 1 shows a typical runtime dashboard executing a Hello World LD program.
Version 1.2b provides a simulator for testing LD programs but can program additional Arduino platforms and popular microcontrollers like the ESP32 and the ESP8266 programmable devices.

Raspberry Pi logiikkaohjaimen moottoriksi
https://etn.fi/index.php/13-news/14196-raspberry-pi-logiikkaohjaimen-moottoriksi
Teollisuuden sulautettujen ratkaisujen kärkinimiin kuuluva Kontron on esitellyt Raspberry Pi 4 -korttitietokoneeseen perustuvan ohjelmoitavan PiXtend Pi 4 -logiikkaohjaimen. KOntron esittelee uutuutta SPS 2022 -messuilla.
PiXtend Pi 4 -logiikkaohjain todistaa ennen kaikkea Raspberry Pi -korttien monikäyttöisyydestä. 4 polven korttitietokone on myös suorituskykyinen, sillä prosessorina on neliytiminen Arm Cortex-A72 -pohjainen Broadcom BCM2711. Sen kellotaajuus yltää jo 1,5 gigahertsiin.
PiXtend-ohjain voidaan ohjelmoida yleisillä ohjelmointikielillä, kuten C tai Python, ja se sopii käytettäväksi CODESYS SoftPLC -ohjaimen kanssa. Moduulit ovat laajennettavissa PiXtend eIO:lla, I/O-järjestelmällä digitaalisille ja analogisille antureille ja toimilaitteille, jotka voidaan liittää Modbusin kautta.
Kaikki ohjaimet ja moduulit ovat saatavana Basic- tai Pro-versioina täydellisenä laitteena DIN-kiskokotelolla

Seeed Studio has announced the launch of a rugged gadget family designed for the Industrial IoT, powered by a Raspberry Pi Compute Module 4: the EdgeBox-RPi-200 range.
Seeed Studio’s EdgeBox-RPi-200 Ruggedizes the Raspberry Pi Compute Module 4 for the Industrial IoT
https://www.hackster.io/news/seeed-studio-s-edgebox-rpi-200-ruggedizes-the-raspberry-pi-compute-module-4-for-the-industrial-iot-11bffffe51ba
With passive cooling and isolated inputs and outputs, this DIN-rail mountable gadget can turn its hand to a range of tasks.
“EdgeBox-RPi-200 series are all-in-one Raspberry Pi-based industrial edge computing controllers,” Seeed Studio’s Jena Liang explains of the company’s latest launch, “combining multiple industrial purposes. Designed as high-scalability and rugged industrial hardware, mounted with rich IO resources and supported by the great Raspberry Pi industrial software ecosystem, it is an ideal choice for smart automation and Industrial Internet of Things (IIoT) solutions.”
The EdgeBox-RPi-200 family, four models strong at launch, may be ruggedized but that hasn’t cut into the feature list: each box includes two isolated digital inputs and another two digital outputs, an isolated RS485 connection, RS232, two USB 2.0 ports, an HDMI 2.0 video output supporting up to 4k60 video, and an M.2 slot compatible with 2242-sized Non-Volatile Memory Express (NVMe) solid-state storage.
On top of that is a gigabit Ethernet port, integrated 2.4GHz and 5GHz Wi-Fi, Bluetooth 5.0 and Bluetooth Low Energy (BLE) support, and a mini-PCI Express (mPCIe) slot for optional 4G cellular, LoRaWAN, or Zigbee radios.
Seeed says it is positioning the EdgeBox-RPi-200 range for a wide range of use-cases, from programmable logic controller (PLC) and programmable automation controller (PAC) work to IoT gateways, local server, and even industrial-grade personal computing. Interestingly, the company is also working on a variant that does away with the Raspberry Pi Compute Module 4 altogether — instead packing an Espressif ESP32 microcontroller and an embedded 4G module, to be launched later this month as the EdgeBox Lite.
The EdgeBox-RPi-200 is now available from Seeed Studio’s web store, priced at $229, $239, $269, and $279 for the four models respectively; pricing for the EdgeBox Lite has not yet been confirmed.

Arduino-kortti taipuu nyt logiikkaohjaimeksi
https://etn.fi/index.php/13-news/14226-arduino-kortti-taipuu-nyt-logiikkaohjaimeksi
Arduino tunnetaan yhtenä rakentelijoiden suosituimmista korttitietokoneista sekä liitettävyytensä että suorituskykynsä ansiosta. Kortteja käytetään myös ammattikäytössä ja nyt Arduinon Pro-sarjaan on saatu uusi laite. OPTA on mikrokokoinen logiikkaohjain, joka tukee erilaisia teollisuuden IoT-liitäntöjä.
Opta on suunnitteltu erityisesti PLC-insinöörejä silmällä pitäen: se tukee vakiokieliä, kuten LD (Ladder Logic Diagram) ja FBD (Function Block Diagram) ja antaa ammattikäyttäjille mahdollisuuden laajentaa teollisuus- ja rakennusautomaatioprojektejamme hyödyntäen Arduinon tuttuja etuja: avointa lähdekoodia ja helppokäyttöisyyttä.
Optan Arduino on kehittänyt yhdessä Finderin kanssa, joka tunnetaan tehtävänkriittisten sähkömekaanisten ja elektronisten komponenttien veteraanina. Sisäänrakennettujen liitettävyys- ja koneoppimisominaisuuksiensa ansiosta Opta avaa uusia mahdollisuuksia teollisuusautomaatioon.

https://www.hackster.io/news/seeed-studio-unveils-the-edgelogix-rpi-1000-an-industrial-raspberry-pi-controller-with-touchscreen-68eac1a17694
4.3″ touchscreen display offers an all-in-one industrial control and automation station, with up to 8GB of RAM and 32GB eMMC storage.
Seeed Studio has launched another Raspberry Pi Compute Module 4 (CM4) board targeting the Industrial Internet of Things (IIoT), and this time it brings with it a wealth of input/output (IO) and a touchscreen user interface: the EdgeLogix-RPi-1000.
“Seeed has launched EdgeLogix-RPI-1000, which extends the widely developed series of the industrial controller,” explains Seeed’s Jena Liang in the company’s announcement. “We would say Raspberry Pi could be a choice for the industry since it supports a huge network of connections among devices, remote monitoring, communicating with devices from different brands, embedded software systems, and dealing with tons of data.”
The carrier board for the system-on-module offers an impressive array of connectivity options: 24 isolated digital inputs and outputs, RS485, RS232, and no fewer than three gigabit Ethernet ports, a high-speed local bus, mini-PCI Express (mPCIe) slot for optional cellular and LoRaWAN radio modules, integrated dual-band Wi-Fi, and optional expansion modules that offer additional digital inputs and outputs and analog-to-digital conversion (ADC) inputs.
Everything is housed in a custom-designed ABS case, with the rear panel doubling as a hefty aluminum heatsink — while the front is dominated by a full-color 4.3″ touchscreen display, designed to provide a human-machine interface (HMI) without the need for additional hardware.
The launch comes two weeks after Seeed announced another Raspberry Pi-powered edge device, the EdgeBox-RPi-200. Packing a Raspberry Pi Compute Module 4 inside, the EdgeBox-RPi-200 is also focused on the Industrial IoT and smart automation systems — but lacks the integrated display while having fewer inputs and outputs.
The EdgeLogix-RPi-1000 is now available for pre-order at $459 with a 2GB CM4, $479 with a 4GB CM4, or $509 with an 8GB CM4; the EdgeBox-ESP-100 is currently in stock and shipping at $179.
