EL 260 - Programmable Logic Controllers

Credit Hours: 3

Introduction to PLCs; PLC architecture; memory addressing and I/O addressing; scan time; ladder logic programming; timers and counters; I/O modules; arithmetic instructions; sequencer instructions and troubleshooting PLC systems. Experiments include: PLC I/O characteristics; sinking and sourcing; reading digital inputs and producing on-off outputs; window comparators and alarms; motor control logic; time delays and timer intervals; counting events; reading AC inputs and controlling AC loads; sequencer control; troubleshooting PLC systems and PLC communications; controlling PLC and loads from touch-screen panel interface.

Course Outcomes
At the completion of the course, the student should be able to:

  • identify and use symbology of ladder logic;
  • write and execute programs using timers, counters and sequencing;
  • understand the PLC architecture;
  • choose the appropriate I/O loading configuration;
  • identify and interpret data manipulation and arithmetic operations for the PLC;
  • properly connect a PLC to control digital or analog devices;
  • properly program touch-screen interface modules and connect them to PLC; and
  • effectively work as a member of technical team on larger design projects.
