See also: Diode logic § Active-high AND logic gate Open-collector buffers connected as wired AND.. The wired AND connection is a form of AND gate.When using open collector or similar outputs (which can be identified by the ⎐ symbol in schematics), wired AND only requires a pull up resistor on the shared output wire.
A number strip would be peeled out and wrapped around the wire near the end. Wire numbers were made up of a series of the number strips so wire 1051 would be four strips. There are also pocket sized printers that print onto an adhesive backed label that can be wrapped around the wire. The basic format for relay logic diagrams is as follows: 1.
Instruction list (IL) is one of the 5 languages supported by the initial versions of IEC 61131-3 standard, and subsequently deprecated in the third edition. [1]It is designed for programmable logic controllers (PLCs).
Similarly, a parallel set of instructions will perform a logical OR. In an electromechanical relay wiring diagram, a group of contacts controlling one coil is called a "rung" of a "ladder diagram", and this concept is also used to describe PLC logic. Some models of PLC limit the number of series and parallel instructions in one "rung" of logic.
Dolby Surround Pro Logic is the full name that refers to the matrix surround format and decoding system in one. When a Dolby Surround soundtrack is created in post-production ( Dolby MP Matrix ), four channels of sound are matrix-encoded into an ordinary stereo (two-channel) soundtrack.
The Dolby Pro Logic Encoding Matrix table appears to have five channels. I thought that Dolby Pro Logic was a four-channel format, and that five channels were not added until Pro Logic II? Am I confused and do I misread the article text? jhawkinson 05:00, 18 May 2007 (UTC)
Function Block Diagram is one of five languages for logic or control configuration [2] supported by standard IEC 61131-3 for a control system such as a programmable logic controller (PLC) or a Distributed Control System (DCS). The other supported languages are ladder logic, sequential function chart, structured text, and instruction list.
The control unit (CU) is a component of a computer's central processing unit (CPU) that directs the operation of the processor. A CU typically uses a binary decoder to convert coded instructions into timing and control signals that direct the operation of the other units (memory, arithmetic logic unit and input and output devices, etc.).
