Schematic Block Diagram for Programmable Logic Controllers (PLC) Programmable Logic Controllers (PLC) and Programmable Automation Controllers (PAC) are process and control implementations that cover ...

Abstract: This article proposes and investigates a scheme of Programmable Optical Digital Logic Computing Array (PODLCA) which mainly consists of basic blocks using dual-drive Mach-Zehnder modulators ...

These blocks become the basic cells of the cellular arrays, the basic "functional units" for the customized interconnection schemes, and determine the terminal control signal sets in the programmable ...
