In this program, students will be introduced to the discrete programming instructions that are used in the implementation of electromechanical control using a PLC, which are the basic relay instructions. This module explains the operation of the basic on-delay and off-delay types of timers and how to program them in a PLC application. Also covered are the special considerations that you must take when implementing timer control programming.
In this program, students will be presented with the implementation of PLC control from electromechanical control. The examples involve the control of motors as well as the implementation of Forward/Reverse control using a Fwd/Rev motor starter. The module explains how to go about to assign the input and output addresses that will be used in the PLC. Also covered are the troubleshooting of PLC inputs and outputs as well as the CPU and how to implement basic PLC preventive maintenance.
