PLC Training Seminar is designed to give the attendees a basic understanding of Programmable Logic Controllers and how PLCs function and to give a brief history of the PLC (Where they came from, where they are today and where they are going). This PLC training seminar will not make the attendees PLC experts, but rather give them a basic understanding of the PLC, the PLC’s functionality and limitations. The PLC training seminar is generic in nature and applies to all types and manufacturers.

PLC Training is also designed to help delegates keep abreast of the latest PLC technologies and techniques available in this area, this tutorial offers an excellent opportunity for delegates to ask specific questions and exchange ideas relating to their own applications.

WHO SHOULD ATTEND:

• PLC Engineering and design personnel
• Maintenance and technical services personnel
• Process and operations personnel
• Technical and process managers
• Engineering and design personnel
• Electrical consulting engineers
• Electrical contractors
