Brief and comprehensible guide for choosing the software for your UniPi PLC. 

What you need to consider

Our products are compatible with several software platforms, some of which are developed by our team. Other platforms for automation systems are developed by third party development teams.

When choosing the right software for your controller unit, there are several questions to consider: 

  • Is the given software compatible with the control unit?
    Software developed and provided by our team is compatible with all our products, but the development of other software platforms and their compatibility with our products is a responsibility of third-party developers. If you're not sure whether or not the third-party software is compatible with our products, we recommend using our native software
  • To what extend is the software supported?
    Third-party developers provide their own documentation, manuals and support for their software. If you cannot find solution for a problem, you may post your question on their or our forum. Documentation, manuals and support for our software can be accessed either via our website, or by contacting our technical support. 
  • Open source or proprietary software?
    Open source software can be developed or edited by anyone. That means users can experiment and create their own programs and share its source code freely. Commercial software does not offer advantages of open-source solutions, they can however offer a better support, dynamic development and more user-friendly interfaces. 
  • What will be your product used for?
  • The answer here greatly depends on the specific application you want to use our product in as each software offers slightly different features and functions. For commercial projects and industrial systems is suitable a software in accordance with IEC 61131-3. For Smart Home it is good to use platforms which focuses on such application and offers convenient functions and visually appealing interface. But most importantly it always depends on your individual needs.
  • What technology are you going to use in your project?
    Each software platform may not support all the protocols, devices and third-party products. Be sure to first check the software developer and make sure the desired technology is supported.
