Title: Describe the basic functions and design of PLCs.
Course: Mechatronics III (13901-III) > Section: Understanding Programmable Logic Controller Systems

Description should include

- central processing unit (CPU)
- digital input (DI) modules
- digital output (DO) modules
- analog input (AI) modules
- analog output (AO) modules
- extension modules
- power supply.

Process/Skill Questions:

- How does the PLC store and process signals?
- How does the PLC receive and transmit information to transducers (e.g., sensors, actuators)?
