Troubleshooting of Data Acquisition & SCADA Systems

This course covers all aspects of data acquisition and control using a PC and data loggers, including design, specification, programming, installation and configuration. The popular IEEE 488 interface is also covered in detail.

The course gives both the novice and experienced user a solid grasp of the principles and practical implementation of interfacing the PC and standalone instruments to real world signals. Upon completion of the workshop you will have a thorough understanding of PC based data acquisition systems and will be able to design, specify, install, configure and program data acquisition systems quickly and effectively. An additional aim of the workshop is to cover the industrial communications standards that are used with instruments today.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

• How to install and configure a data acquisition system
• Why over 30% of data acquisition systems give incorrect results
• How to choose and configure the correct software
• State of the art approaches in design of data acquisition systems
• How to configure data communications systems
• How to avoid the common pitfalls in designing a data acquisition system

Who Should Attend?

This course is intended for all design engineers, electrical engineers, electronic engineers, instrumentation and control system engineers, process control engineers, project engineers, systems engineers and technicians.
