In the winter semester of the 2019/2020 academic year, rebuilt teaching laboratory stands were launched in the Systems Automation Laboratory run by the Department of Control Engineering.
As part of the reconstruction, existing laboratory stands with Saia Burgess industrial controllers were supplemented with additional PLC controllers, SANYU SX1000 or Sinamics V20 frequency converters and three-phase low-power motors.
Teaching facilities developed in this way include:
- Saia PCD1 or Saia PCD3 PLC devices
- Saia WEBpanel MB operator panels
- SANYU SX1000 or Sinamics V20 frequency converters
- three-phase AC motors
- setpoints and input / output indicators.
The stands are used to design and test distributed control systems, among others, as part of classes on subjects Automating industrial processes and Integration and visualization of automation systems in the field of robotics automation and control systems.
Learning to integrate control systems is based on the students' analysis of the control system design, description of the project in terms of automata theory, and then its programming and testing on laboratory positions. Implemented control systems include:
- control system based on a PLC controller with local control
- control system based on a PLC controller with remote control via LAN and HTTPS protocol
- control system based on a PLC controller with remote control via network and Modbus RTU protocol.
The control objects in all systems are low-power three-phase motors powered from frequency converters.
As part of the classes using laboratory stands, students will learn about many practical issues in the field of industrial automation, including:
- programming distributed control systems using the Modbus RTU network and Modbus TCP
- programming sequential drive control systems powered by frequency converters
- designing HMI visualizations for control systems.
The author of the project for the reconstruction of laboratory stands is Ph.D. Eng. Krzysztof Kamiński from the Department of Control Engineering. SANYU SX1000 frequency converters used for the reconstruction of laboratory stands were made available free of charge by SANYU Sobczak Spółka Jawna from Chorzów.
