PLC Training Part 6: In part 6 your students will learn about move instructions, the binary numbering system, decimal numbering system, how to count in octal, hexadecimal and BCD digital formats. They will also learn how to easily convert from one format to another. Since PLC systems are digital in design, this training is vital. PLC Training Part 7: Here your students learn how the PLC can be used to monitor and control a servo valve or servo motor. Part 7 examines the characteristics of the analog signal and digital signal. It then progresses into basic open loop and closed loop servo control systems. In this training segment your students will also learn proper preventative maintenance procedures for the PLC system, how to read and understand flow charts, error codes and fault registers. Basic troubleshooting procedures are also covered in this portion of the PLC training. PLC PLC Training Part 8: In the final training session your students will learn how to systematically localize faults to either the input, output or logic section of the PLC controller. They will learn how to troubleshoot with, or without the use of the program monitor. Part 8 concludes with basic Safety procedures when working on PLC systems plus an over view of the material covered in the previous 7 sessions. Table Of Contents
