PLC Telemetry and SCADA Technologies



This is a highly relevant, industrially based course that will update the skills and knowledge of Technicians and Engineers alike. The course is ‘hands-on’ using industry-standard PLC’s in a simulated environment. Through this approach, the delegate will progress from learning the fundamentals of PLC application to writing, debugging, and finally designing their own programs.

Radio and wire-based telemetry systems, essential for an understanding of modern communication methods deployed in the field are also studied and explained. These are vital for a comprehensive understanding of their use with not only programmable controllers but any Instrumentation/Controller remote application.

The course also includes a study of modern SCADA technologies. Again, together with a hands-on approach using a modern industrially compliant SCADA software package, the delegate will acquire new and updated skills essential in any fast-moving industrial environment.

Course Objectives:

At the end of this course the participants will be able to:

  • Give an understanding of the operation, architecture, and use of an industry-standard PLC for Control purposes.
  • Use a hands-on approach, enable the delegate to investigate the operation of the PLC through designing, building, and testing typical programs in the ladder programming language using industry-standard PLCs in a simulated environment.
  • Become familiar and confident with the PLC, Telemetry, and SCADA environments.
  • Understand the concepts of Radio Telemetry and acquire the knowledge relating to the application, limitation, and use of frequency bands used.
  • Gain an understanding and knowledge of common wire-based communication protocols.
  • Disseminate and share experience and knowledge with other delegates through open session discussions hence broadening the knowledge base of all.
