HELIO Playground PLC

A Soft-PLC designed for testing and simulating HELIO HMIs using OPC-UA.

The HELIO Playground PLC is a software tool designed for your development machine, acting as a PLC simulator.

  • It provides an API based on OPC-UA with sample variables.
  • Use it to follow the getting started tutorials like Build Your First HELIO HMI Using the HMI-Driven Approach.
  • Test your HMIs using OPC-UA when there is no PLC backend available for simple testing.
  • Run and test HELIO Project Templates against a PLC backend.

Running it​

Just like HELIO the Playground PLC is also a simple executable that you can execute on your development machine.

Make sure that your firewall does not block the server!
