Programmable logic controllers (PLCs) are used extensively throughout the world. Over time, they have advanced to become more user-friendly, efficient, smaller, and less expensive. Different types of ...

Boolean algebra is the combination of logic and algebra, initially developed by George Boole, for whom the subject is named, in the 1840s and '50s, and later refined by other logicians through the ...

His lasting theory, Boolean logic, is a form of algebra where all the values (or variables) are either "true" or "false".

Mathematical logic, set theory, lattices and universal algebra form an interconnected framework that underpins much of modern mathematics. At its heart, mathematical logic provides rigorous formal ...

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 ...
