How does LadderWORK work?

LadderWORK programs are a mix of two languages called LD ( Ladder Diagram ) and FBD ( Function Block Diagram ). Their appearance and operation imitate electrical circuits. However, they are analogous to functions from conventional script language programs. Each of the possible elements of the component library represents a module of the program. When the user selects and places a new component on the actual project layout connecting it by wires to the circuit automatically he links the correlated program module to the program under construction. During the compiling phase the diagram is then translated in a microprocessor-compatible program which can be sent and stored to the PLC
