Programmable Controllers

This teaching set provides a complete introductory package for Programmable Logic Control (PLC) teaching. The set features a conveyor belt based workcell with a series of sensors and pneumatic actuators that allow a parts selection task to be carried out.

The Package features an industry standard Allen Bradley Micrologix 1500 PLC with remote programming software.

The student workbook provides a structured introduction to programming PLCs through a series of practical tasks. An instructor’s solutions book completes the package providing typical results and answers to questions.

Typical topic areas include:

• Introduction to PLCs
• ladder logic programming
• latches
• counters
• timers
• shift registers
• sequencers

Typical activities include:

• Identify hard-wired ladder & PLC ladder logic diagrams and its operation.
• Investigate the operation of a ladder logic program.
• Investigate the operation of Examine ON, Examine OFF and Output Energize instructions and their operation.
