The additions of extended and function block instructions to the basic instructions representing relays, timers, and counters, however, have helped ladder diagram programming to remain a flexible and ...

3 Function Block Diagram Function block diagram is another graphical PLC programming language that uses blocks to represent functions, inputs, outputs, and connections.

THE use of function blocks for programming of programmable logic controllers (PLCs) is gaining wider acceptance. Rather than the classic “contact and coil” representation of ladder diagram or relay ...

The graphical programming realm Explaining the principal differences among the graphical PLC programming languages, Yerger started with Ladder Diagram, noting its development from relay logic. “It ...
