Overview
Course Description
This workshop is designed to equip you with practical up-to-date information on the application of PLCs in the automation and process control of plants and factories. It is tailor made for people who have little or no exposure to PLCs, but who expect to become involved in some or all aspects of PLC installation. It aims to give practical advice from experts in the field, to assist you to correctly plan, program and install a PLC with a shorter learning curve and with more confidence.
