RT 650.40 I&C Software for RT 614 - RT 674 Series



  • Software controller with freely settable parameters
  • Continuous and switching controller selectable
  • Language freely selectable
  • Process schematic with display of real-time data
  • Recorder functions


Technical Description

The software ideally supports the experimentation and learning process of demonstration models RT 614 - RT 674. Its key features are the software controller and the recorder function. The controller can operate as a configurable PID controller and as a 2-point controller. In the latter case, as well as the setting of the reference variable, the hysteresis can also be pre-set. The recorder function provides continuous recording of controlled, manipulating and reference variables. It plots responses to changes in the reference (e.g. step input) and disturbance variables. Measured values can be printed out and saved to data media. Connection to a PC is by a USB port. The supplied USB interface module provides an adequate number of analogue inputs and outputs, enabling even complex circuits, such as a cascade (RT 674), to be controlled.

The controller included with each demonstration unit can also be used instead of the software controller. In this case, controlled, manipulating and reference variables can be plotted, displayed and saved by the program's recorder function.

Choosing different program windows makes it possible to display the relevant process schematic with locally assigned real-time data and the time functions of these parameters.

The learning process is assisted by the well structured manual, with its description of the software functions and instructions for use with the control engineering demonstration models RT 614 - RT 674.
