Introduction
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 in 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.
Some of the main topics covered include:
- A study and explanation of the PLC for Control purposes
- Understanding through ‘hands-on’ approach using industry-standard PLC’s in a simulated environment of PLC programming – design and debugging
- Investigation of Radio telemetry methods, frequencies used, and application and limitation of each frequency band
- A case study in the design of a Radio Telemetry link
- Study of commonly used wire-based telemetry methods and protocols such as RS232 and RS485
- Investigation of SCADA, its structure, and application. Understanding of a typical SCADA application through a hands-on approach using an industry compliant SCADA software package
Course Objectives of PLC Telemetry and SCADA Technologies
The main objectives of this seminar are:
- To give an understanding of the operation, architecture, and use of an industry-standard PLC for Control purposes
- By using 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 PLC’s in a simulated environment
- To allow the delegate to become familiar and confident with the PLC, Telemetry, and SCADA environments
- To understand the concepts of Radio Telemetry and acquire the knowledge relating to the application, limitation, and use of frequency bands used
- To gain an understanding and knowledge of common wire-based communication protocols
- To disseminate and share experience and knowledge with other delegates through open session discussions hence broadening the knowledge base of all
Course Methodology of PLC Telemetry and SCADA Technologies
The seminar is delivered via a series of mixed activities which will at times involve delegate participation. Theoretical content is delivered by informal lecture and discussion and supplemented where appropriate with tutorial sessions using worked examples.
An important part of the program is the hands-on aspect. Using industry compliant software and PLCs, approximately a third of the total time will be devoted to practical activities. Delegates will acquire the skills and confidence to investigate, debug, and where necessary modify and/or design their own control systems employing a PLC.
Organizational Impact of PLC Telemetry and SCADA Technologies
By attending this seminar the delegate will return to their company more confident in the knowledge and use of PLC, Telemetry, and SCADA systems. More specifically, they will:
- Be equipped with new skills and knowledge which must impact positively within the company structure
- Be able to evaluate the suitability and application of current in-house PLC/SCADA systems and offer guidance and advise on whether such systems may be modified or improved
- Consequently, be able to leverage their skills to potentially cause an increase within the plant or process in terms of overall productivity and efficiency through analysis of current systems
- Be better equipped to advise on new system communication installations in terms of evaluating choices between radio and wire-based telemetry systems
- Potentially through their newly acquired knowledge and understanding of PLC systems and their integration into a SCADA system using a variety of digital communication standards and telemetry links be able to advise system designers, thereby negating or at least reducing the dependency on external agencies and vendors
- Therefore potentially contribute towards and result in plant and process cost reductions leading to financial savings for the company
Personal Impact of PLC Telemetry and SCADA Technologies
The delegate will benefit personally from the attendance of this seminar and will enhance their own knowledge base and level of confidence in the area of PLC, SCADA, and Telemetry systems. Specifically, the delegate will be able to:
- Return to their organizations equipped with new skills and knowledge that will enable them to understand, analyze, and optimize their own plant requirements in terms of PLC and SCADA systems
- Design, construct, download, and evaluate PLC programs written in a standard programming language to meet a given specification
- Develop a working knowledge of basic and advanced PLC and SCADA programming techniques
- Predict the suitability of a Radio telemetry system by a study of the terrain under investigation and by gaining a knowledge of the operating parameters of the frequency bands available
- Make informed decisions on methods of conveying data from RTU’s by an acquired understanding of commonly used wire-based data communication protocols such as RS232 and RS485
- Upgrade their level of confidence in PLC based systems and determine the appropriateness of new system design in terms of PLC/SCADA or a DCS configuration
