Mechatronics Certification Tests

Mechatronics Certification Test - Programmable Logic Controllers (PLCs) 1

This certificate covers the principles and applications of different types of logic and programming used to control packaging machinery and systems. Topics include hardware and software composition of control systems, input/output interfacing, basic logic commands and common programming instructions. There is additional emphasis on common program tasks, and troubleshooting PLC  based systems.

Knowledge of relay logic, ladder programming and input/output devices is needed to understand and maintain all types of common packaging equipment.

This certificate is aimed at entry level technicians who may be involved in the assembly, test, start up, troubleshooting, maintenance, repair or upgrade of basic packaging machinery modules.
