Five different programming languages — ladder diagram, function block diagram, structured text, instruction list, and sequential function chart — are defined in the IEC 61131-3 standard, as ...

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 ...

When a PLC is used primarily to replace relays, timers, and counters, it's hard to beat the simplicity and usefulness of ladder diagram programming.Their ability to accept programming in ladder ...
