PLC Training

A Programmable Logic Controller (PLC), Is More Or Less A Small Computer With A Built-in Operating System (OS). This OS Is Highly Specialized To Handle Incoming Events In Real Time, I.e. At The Time Of Their Occurrence.

A PLC Is Primarily Used To Control Machinery. Programs Written For PLCs Consist In Simple Terms On Instructions To Turn On And Off Outputs Based On Input Conditions And The Internal Program.
