A programmable logic controller, or PLC, is a software-based equivalent of a relay panel. A PLC is a general-purpose device. One model can be programmed to control a variety of machines, and programs ...

Programmable Logic Controllers (PLCs) are the backbone of modern industrial automation, orchestrating critical operations across diverse sectors. As these controllers become increasingly complex, ...

Ladder logic uses switch or relay contacts to implement Boolean expressions. In years past, ladder logic was made possible with discrete relays and was sometimes termed “relay logic.” Today most ...

There are misconceptions about what SoftPLCs can and can’t do. A SoftPLC is a software-based version of a programmable logic controller (PLC). The term SoftPLC has been used for many years, and like ...

There are various approaches to developing programmable logic controller (PLC) applications using experimental techniques. Modifying existing PLC ladder logic programs is another common approach ...
