This module provides a general overview of PLCs and their application in wind turbines. An introduction to ladder logic is presented and the most common types of PLC signals are covered with an emphasis on practical application. This module also covers math functions, PID control and PLC communications, as well as maintenance and troubleshooting of PLCs. Laboratory projects are completed using PLCLogix 500 simulation software. This PLC software features a 3D wind turbine simulator that enables you to run, test, and debug ladder logic programs and simulate the operation of a PLC-controlled wind turbine.
