PLC Level 2- Maintenance & Troubleshooting (3/18-3/21/24)

March 18 @ 8:30 am 4:00 pm

This 4-day training program is designed to be the “next step”  in building competence around the troubleshooting and maintenance of  PLCs.

 This course will provide students with a deeper understanding of the topics covered in the Fundamentals class. Students will improve their troubleshooting skills by learning to program ladder logic projects from functional specifications rather than merely understanding ladder logic provided to them. The course is designed to be a deep dive into the most common ladder logic instructions, a challenging approach to deciding which instructions to use in projects they create and meet the criteria spelled out in the hands-on exercises. This deeper understanding of the instructions and how they function will enhance the end users troubleshooting efficiency.

This class is gear towards those who have taken Level 1  or has basic PLC knowledge.

Students will learn:

  • Know & understand the relationships between Controllers, Chassis, Power Supplies, IO Modules, Terminology, Indicator Lights, Key Switch
  •  Recognize & understand Common Communication Modules
