EMC Lesson 10: Understanding and Applying PLCs in Electrical Controls

This program covers it all—number systems, general PLC operation, and introductory programming. You’ll learn how to convert an electromechanical (hardwired) system to a PLC-based system, I/O addressing, and much more!

This program gives maintenance personnel the skills necessary to troubleshoot the controller and determine whether the problem is with the controller, the wiring, or a field device. PLCs—

What Everyone Needs to Know

• Low-voltage protection is a must when PLCs are used to control motors—we’ll show you how to implement it
• Learn which sections of the control circuit must be left hardwired for safety reasons
• Follow our step-by-step method of converting a hardwired relay system to a PLC-based system
• Troubleshoot the complete discrete I/O system—from power line problems to wiring connections to I/O modules
