Ladder Logic | A programming Language
Ladder logic is a programming language used to develop functional programs in Programmable Logic Controllers (PLCs). It resembles the layout of electrical circuits with two rails, one for positive and one for negative supply, facilitating the representation of inputs and outputs through symbols. Technicians favor ladder logic due to its simplicity, aligning closely with traditional relay logic. This language operates with normally open (NO) and normally closed (NC) contacts and output coils, enabling current flow only through closed contacts. Special components like timers and counters enhance its functionality, allowing for more complex control scenarios in automation tasks.
