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 Design Idea describes a simple alternative to a nonvolatile gating function you typically implement using PAL (programmable-array logic), GAL (gate-array logic), or a CPLD ...

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. Ladder logic diagrams use symbols ...
