Discover everything our most versatile Opta micro PLC has to offer: designed for engineers who need to keep their options open.

Overview

Arduino Opta is a secure, easy-to-use micro PLC with Industrial IoT capabilities. 
Designed in partnership with Finder – leading industrial and building automation device manufacturer – Opta allows professionals to scale up automation projects while leveraging the Arduino ecosystem. Supporting both Arduino sketch and standard PLC languages, including LD (Ladder Logic Diagram) and FBD (Function Block Diagram), it was designed with PLC engineers in mind.

Its powerful STM32H747XI dual-core Cortex®-M7 +M4 MCU allows users to perform real-time control, monitoring and implement predictive maintenance applications.

Secure and durable by design, it supports OTA firmware updates and ensures data security from the hardware to the Cloud thanks to the onboard secure element and X.509 Standard compliance. In addition, Opta undergoes regular assessments to uphold and improve its cybersecurity posture.

All while maintaining Arduino Pro’s signature easy deployment in production thanks to a vast range of readily available software libraries and Arduino sketches.

Last but not least, various connectivity options make keeping everything under control effortless via real-time dashboards combined with the intuitive Arduino Cloud (or third-party services).

Opta comes in three variants so you can choose the best option for your project. Opta WiFi features Ethernet onboard and USB-C programming ports, RS485 half duplex connectivity interface, and Wi-Fi/Bluetooth® Low Energy connectivity.

Program it with the Arduino PLC IDE!

The Arduino PLC IDE makes PLC programming easy. Choose any of the 5 programming languages defined by the IEC 61131-3 standard (Ladder, Functional Block Diagram, Structured Text, Sequential Function Chart or Instruction List) and quickly code PLC applications or port existing ones to Arduino Opta. 

Key benefits include:

  • Easy and fast software development, starting from ready-to-use Arduino sketches, tutorials and libraries
  • Support for standard IEC 61131-3 PLC languages
  • Fieldbus integration via Modbus TCP (ethernet) and Modbus RTU (serial RS485)
  • Seamless IoT connectivity (Ethernet/Wi-Fi/Bluetooth® Low Energy)
  • Real-time remote monitoring via intuitive Arduino Cloud dashboards (or third-party services)
  • Security at the hardware level thanks to onboard secure element and X.509 Standard compliance
  • Secure OTA firmware updates and Cloud device management
  • High-power relay switching (4 x 2.3 kW)
  • Reliable by design, thanks to industrial certifications and Finder’s expertise in switching technology
  • Easy to install, with DIN rail compatibility

Opt in to industrial automation

Integrate a solid and reliable micro PLC with your existing machines, devices and production lines – also in combination with other elements in the modular and versatile Arduino ecosystem, from small and smart sensor-packed modules to SOMs to gateways, for end-to-end solutions that can be customized to meet any need.

Quality by design

Arduino Pro partnered with Finder, a leader in the field of electromechanical and electronic components with 65+ years of excellence and expertise to its name, to create a product with high-quality production specs for even the most demanding work conditions in industrial environments.

Machine-to-machine communication is easier than ever: Opta now supports OPC UA
Machine-to-machine communication is easier than ever: Opta now supports OPC UA
November 5, 2024

OPC Unified Architecture – OPC UA in short – is a cross-platform, open-source machine-to-machine communication protocol for industrial automation. It was developed by the Open Platform Communications (OPC) Foundation and is defined in detail in the IEC 62541 standard. With the release of the Arduino_OPC_UA library we enable users to convert any product from our Arduino Opta range into an OPC UA-enabled device. Step-by-step guide to setting up OPC UA on Arduino Opta It’s as simple as uploading a single sketch onto your Opta and connecting it to an Ethernet network. Once uploaded, the OPC UA firmware exposes the Arduino Opta’s analog and digital inputs, the user button and LED (only Arduino Opta WiFi), as well as its relay outputs as properties that can be read from or written to using OPC UA. OPC UA communication is performed using OPC UA binary encoding via TCP sockets. Arduino_OPC_UA is a port of the Fraunhofer open62541 library implementing IEC 62541 in highly portable C99 for both Windows and Linux targets. One serious challenge during the porting of open62541 was to decide on sensible tradeoffs concerning RAM consumption, as using OPC UAs full namespace zero (NS0) requires up to 8 MB of RAM while the STM32H747 powering the Arduino Opta has a total of 1 MB of SRAM to offer – some of which already allocated by the the Arduino framework for the Arduino Opta. Expand functionality with Arduino Opta Modules and OPC UA integration Additionally, Arduino_OPC_UA supports the automatic discovery, configuration and exposure as OPC UA objects of the recently released Arduino Opta expansion modules. Currently three different expansion modules exist: Arduino Opta Analog Expansion (A0602), Arduino Opta Digital Expansion with electro-mechanical relay outputs (D1608E), and with solid-state relay outputs (DS1608S). During system start-up, the Arduino Opta’s expansion bus is queried for connected expansion modules and automatically configures them and
