4 reasons to use the micro–PLC Arduino OPTA 

Thanks to its computing power, the Arduino OPTA Micro PLC is ideal for a wide range of real-time control, monitoring, and predictive maintenance applications. The benefits of the open and widely recognized Arduino environment contribute to expanding automation projects not only in the industry.

Programming

The Arduino PLC IDE allows you to program Arduino Opta using the five ways defined by the IEC 61131-3 standard:

  • Ladder Diagram (LD)
  • Functional Block Diagram (FBD)
  • Structured Text (ST)
  • Sequential Function Chart (SFC)
  • Instruction List (IL)

“Arduino Opta allows combining PLC programming according to IEC 61131-3 with Arduino sketches (C++) within an integrated sketch editor and seamlessly accessing variables between these two environments," says Miroslav Piskor, Product Specialist at SOS electronic. 

Security

Hardware level

  • ATECC608B cryptographic co-processor

Variants

Typical use cases

  • Controlling compressors in paint lines 
  • Managing flow circulation and liquid discharge control in water treatment plants 
  • Monitoring levels and automatic tank replenishment 
  • Automated packaging line 
  • Predictive maintenance of existing machinery
  • HVAC

Why choose Arduino Opta?

  1. Interoperability and no vendor lock-in
    (Vendor lock-in: the cost of switching to another supplier's product is so high that the customer is essentially forced to continue using the original supplier's products)
  2. Best-in-class security
  3. Massive talent pool in the Arduino community
  4. Similar or better features than micro PLCs from well-known brands such as Siemens Logo!, Rockwell Micro810, or Schneider Zelio Logic
