The PID Tuner is more than just a PID Tuner. With only one push of the button, you create a Digital Twin, also known as Real-Time Simulator. Your control software / hardware (PLC of DCS) can communicate directy with the Digital Twin. How we do this? The Digital Twin is another OPC Client (just like the PID Tuner) and your PLC / DCS. Therefore, the your control system can cmmunicate directly with the Digital Twin (read/write tags). The advantages of using a Digital Twin are numerous, among which: (1) zero risks, (2) no loss of time, (3) prepare commisioning , (4) optimisation of the control system.
