Op1: LD Ladder diagram - This is a method of drawing electrical logic schematics. It is a very popular graphical language for programming Programmable Logic Controllers (PLCs). It was originally invented to describe logic made from relays. The name is based on the observation that programs in this language resemble ladders, with two vertical rails and a series of horizontal rungs between them. IN
