In its most widely used traditional form (particularly in the oil and gas industries) a Supervisory Control and Data Acquisition (SCADA) system acts as an adjunct to a larger control system – comprising a number of remote terminal units (RTUs) that collect field data and connect back to the system controller via a communication system. In its other form, SCADA is used as a standalone system to monitor and control a plant using PLCs as ‘hardened’ robust front-end devices providing a ‘window’ into the process.

However, SCADA systems are evolving, and the emphasis today is on using Open Standard communication protocols such as IEC 60870, DNP3 and TCP/IP together with ‘off-the- shelf’ hardware and software to provide greater flexibility and connectivity.

This comprehensive workshop, ‘Supervisory Control and Data Acquisition (SCADA) Systems’ covers all the essentials of a SCADA system including: SCADA architecture and topology; system elements; communication and interconnectivity; and cyber security issues.

On successful completion of this workshop delegates will be able to:
 recognize the different components of a SCADA system
 appreciate the basic principles of data communications
 evaluate the requirements for PLC-to-SCADA communications
 understand the basis of cyclic redundancy
 appreciate the use of radio in the industrial environment
 evaluate the problems associated with database management
 recognise the wide range of modulation techniques
 apply Modbus in a practical manner
 evaluate the relative merits of IEC 60870 and DNP3 SCADA protocols
 gain insight into the challenges faced by cyber security

Software simulation:
An HMI simulation program, incorporating all of the major features of a typical SCADA system, will be made available to delegates for the duration of the course in order to experiment with practical SCADA concepts, in a safe and controlled environment.

Delegates are encouraged to bring their own (non-Apple) laptops.

Note. In order for the software to be loaded onto these machines, administrator rights may need to be obtained.

Other practical sessions include: exercise on radio telemetry path-loss design and performing an intermodulation products calculation.
