Temperature Control – PLC On-Board
A centrifugal pump makes the hot water recirculate from a heating tank to a plate-type exchanger cooled by tap water.
Temperature is measured by a thermoresistance and it is controlled by a pneumatic valve inserted in the inlet line of cold water.
The on-board PLC includes a PID algorithm block and is able to manage the unit through an Ethernet communications module.
This module allows the PLC to work together with an operator panel for the information exchange.
The panel has several graphic pages, with the unit synoptic diagram, the open and closed control loop main parameters, and the graphic of the system response according to the working situations
This unit enables to develop and analyze the following subjects:
- Proportional, Integral and Derivative control
- Open-loop control
- Closed-loop control
- Tuning a controller
- Response to a noise
