MEC 108 - Programmable Logic Controllers 1
Credits: 3
2 Lecture Hours 2 Lab Hours
Description
In this course, students perform a series of hands-on exercises in the lab as an introduction to programmable logic controllers (PLCs). Topics include connecting inputs and outputs to the PLC, writing, downloading and debugging ladder logic programs. Additionally, students troubleshoot existing PLC circuits and programs.
Learning Outcomes
Upon successful completion of the course, the student will:
- Identify the components of a compact and modular PLC system.
- Connect the input and output terminals of a PLC to sensors, actuators and AC or DC power supplies.
- Describe different input and output terminals using slot:rack and tag-style addressing.
- Create ladder logic programs to dynamically control outputs using specified input conditions.
- Utilize timers, counters, latches, bits and mathematical operations to automate manufacturing processes.
- Troubleshoot common PLC operational issues including serial, USB and network connections.
- Explain the risks of connecting embedded systems to the internet.
