Course description
Whether you are new to PLCs or are familiar but in need of a good refresher, this course is the right starting point.
This course will give an essential and fundamental overview of Programmable logic Controllers. It will cover the operation and basic programming of PLCs as well as their troubleshooting and maintenance, programming software, ladder or code design, and functionality. This will be accomplished using the supplied Horner Automation XL4 OCS (Operator Control Station) PLC's which shall be used by each student within the course.
The attendees will be able to work through basic programming and set up for this PLC and understand how the PLC can be applied in simple or complex control applications. In a controlled environment, students will understand and safely connect, program, and operate the PLC to further understand its function as well as associated terminologies, programming instructions, and programming revision control, editing, and simple troubleshooting.
Through the hands-on labs, students will work through the simple programming examples on the OCS and be able to monitor the PLC with the included CScape software.
