Concept of the project

Control and SCADA h_da Darmstadt

The task of the project is to design and to realize the temperature cascade control of the batch reactor-model The engineering will be done by three groups

UTC Weblab

Inner-loop Design UTC WebLab, Tennessee Remote Experiments

Group Y Group Z Group X

Main-loop design h_da Darmstadt Model of Reactor UTC WebLab, Tennessee Remote Control h_da Darmstadt h_da Darmstadt

Project Structure

After receiving the inner loop transfer and the step response, the group X calculated the transfer function of the plant. They develop the main PID controller and simulate the whole loop with LabVIEW It is supposed to send the results to the UTC-project group. The group Y is getting experiments values from the UTC WebLab. From this results they get the transfer function of the inner loop. They send the result to the groups X and Z. After wiring the PLC, the group Z were programming the level and temperature control and get the step responses from the reactor. They send the step responses to the group X.

PLC Software Architecture

  • Program is separated in Function Block Diagrams (FBD)
  • Few reusable parts programmed in Function Blocks (DFB)
  • One FBD for each Use Case (UC)
  • FBD 5&6: Cascade Control with controller parameter values from Group X
  • Commissioning with the help of GUI

Group Z: GUI Development

  • Programming the GUI in NI Lookout Software
  • PC is connected via RS 232 to the PLC
  • Addressing and defining of variables to be used in the GUI
  • 3 UC’s are defined in the requirements
  • ->2 main functional parts = PLC display + monitoring display
  • ->1 additional/auxiliary part = commissioning i/o

Group Z: GUI Development

PLC Display

  • Shows the states of all PLC inputs

and outputs

  • Interface for the operator: Buttons

Start/Stop and manual operating functions

  • Desired temperature is set by

simulation model via potentiometer Monitoring display

  • Displays continuously the

changing of all system variables

  • Tool for observing control loop

behavior while commissioning, maintenance and operation
