What Is PLC Programming
PLC PROGRAMMING IN MANUFACTURING PLC-based automation helps manufacturers across Canada keep a competitive edge in an ambitious, technological world. WHAT IS PLC PROGRAMMING? PLC programming is the act of creating internal logic for a programmable logic controller (PLC). PLCS are typically programmed in a "language" proprietary to the controller. BENEFITS TO INDUSTRY LANGUAGES Ladder logic (most common) Minimizes the monotony of simplistic work tasks Simplifies wiring Structured Text SFC (Sequential Flow Chart) Reduces material costs Replaces outdated mechanical methods with dynamic complex routines Instruction List Function Block Diagram THE PLC IS THE BRAIN OF AN AUTOMATED SYSTEM START SCAN INTERNAL CHECKS A specialized computer that performs singular tasks at astronomically fast speeds. SCAN INPUTS Can handle thousands of i/o processes with a single CPU. EXECUTE PROGRAM LOGIC UPDATE OUTPUTS POWER SUPPLY CENTRAL PROCESSING UNIT Produces OUTPUT mechanical MODULE and other Provides sensory INPUT input to the MODULE machine CPU motions RACK The brain of the PLC it handles the mathematical RACK heavy lifting required to run an automated system at an extreme speed.
