Ladder logic is widely used to program PLCs, where sequential control of a process or manufacturing operation is required.Ladder logic is useful for simple but critical control systems or for reworking old hardwired relay circuits. As programmable logic controllers became more sophisticated it has also been used in very complex automation systems.

PLC Ladder Simulator is a simulator for the Android operating system with input and output objects that simulate the I/O ports of a real PLC. You can used PLC Ladder Simulator to create ladder-logic diagrams using components from the standard set used in these diagrams.
