Ladder logic diagrams are one of the most common ways to program a PLC (programmable logic controller), a device that controls industrial processes and machines.

Programmable logic controllers (PLCs) are widely used in industrial electronic systems. With the augmenting complexity of system, the reliability poses a crucial challenge in safety critical ...

This paper describes the architecture of a retargetable ladder diagram based software tool for programmable logic controllers (PLCs), which is based on the IEC 611311-3 specification. We propose here ...

On the surface, a programmable logic controller (PLC) might seem like nothing more than a generic microcontroller, perhaps outfitted to operate in industrial settings with things like high ...

Ladder logic is the basis of most control functions Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and ...
