Course Overview

This course covers the content from PLCC104 to PLCC106. In the first section the participants will learn the fundamentals of Function Block Diagrams with a focus on discrete instructions, timer instructions and program control instructions. Participants will learn to write programs, apply them on real world applications and devices.
The second section provides a brief introduction to Structured Text and introduces Sequential Function Charts with a focus on the elements of SFC.
The third section covers the methods that computers and other discrete components used to work together with PLCs to provide effective communication systems. This section will also cover communication systems including PLC to PLC communication, Ethernet, serial and discrete-bit communications.

Expected Outcomes
Upon successful completion of this module, the participant should be able to:

  • Implement discrete instructions, counters, compare, add-on instructions and other programming statements.
  • Implement subroutines.
  • Independently program and apply the function block tools on devices and troubleshoot.
  • Identify and use discrete functions.
  • Implement subroutines.
  • Use timer, counter and add-on instructions.
  • Configure RS232 components to communicate between devices.
  • Configure Ethernet network devices to communicate with each other.
  • Configure discrete communications between machines using interposing relays.
  • Establish a communications link between PLCs using Ethernet and discrete communications.
