Ladder logic has evolved into a programming language that represents a program by a graphical diagram based on the circuit diagrams of relay logic hardware. Ladder logic is used to develop software for programmable logic controllers (PLCs) used in industrial control applications. See more Ladder logic was originally a written method to document the design and construction of relay racks as used in manufacturing and process control. Each device in the relay rack would be represented by a … See more Ladder logic is widely used to program PLCs, where sequential control of a process or manufacturing operation is required. Ladder … See more Ladder notation is best suited to control problems where only binary variables are required and where interlocking and sequencing of binary is the primary control problem. Like all parallel programming languages, the sequential order of operations may be … See more • Walker, Mark John (2012-09-08).
