HIL Simulation

HIL simulation enables you to test PLC software without using a real machine.

What is HIL Simulation?

Our digital twins can be coupled to a PLC running the control software of a machine. This allows you to test the control software, without using the real machine. This type of testing is known as Hardware-in-the-Loop (HIL) simulation. HIL simulation is typically applied when the real machine is not available or very costly to use.

Setup

A HIL simulation set up consists of a PC running the digital twin connected with a PLC running the control software.

  • A keyboard, mouse and HIL HMI are used to start the simulation and choose a test.

  • An operator panel and operator HMI are used to give the machine input during the test.

  • The machine behaviour is shown in the displays using in 3D animations and plots.

PLC

We couple our digital twins to your PLC using one of the following communication protocols to exchange data:

  • TCP/IP

  • UDP

  • OPC-UA

  • CAN

  • Modbus

  • Bachmann M1COM,

Most of the PLC brand support these protocols. We have good experience with Siemens (S7, S7-1500), Beckhoff, Bachmann and Rockwell.
