The RT 451 – 455 series is constructed entirely from industrial components in order to teach control engineering in a practical manner. The use of smart sensors lays the foundations for Industry 4.0 applications. Smart sensors provide signal processing in addition to the capture of measured values thanks to integrated evaluation electronics. Besides process data, it is also possible to exchange configuration, diagnostic or statistical data. In practice this makes it faster to change over production lines, for example, or enables predictive maintenance.
The RT 454 trainer has all components required for an open and closed control loop. The controlled system is a pipe section with temperature measurement at different positions which is passed through by water. Two integrated selectable process delay pipe sections allow dead times to be represented. The temperature as the controlled variable can optionally be recorded by one of the three smart temperature sensors. The actuator in the control loop is a heater and/or a heat exchanger with fan as a cooling unit. The control response with switching or continuous control is investigated. The heater can be operated continuously or switching, the fan is operated switching or manually. Defined disturbance variables can be generated by means of a proportional valve with motor drive.
The smart temperature sensors have an IO-Link interface for interference-free transfer of measured values and the exchange of configuration data.
The trainer is controlled and operated via the integrated PLC and the touch screen or via GUNT software (external PC required). The control response is displayed in the form of a time function. The network capable software makes it possible to follow and analyse the experiments at any number of workstations via a LAN/WLAN connection to the local network.
