An alphanumeric value that identifies where data is stored.
The temperature of the air surrounding a system.
A standard system used for designating the size of electrical conductors.
Larger gauge numbers have smaller diameter.
A Boolean operation that produces a logic "1" output if all inputs are "1", and a logic
"0" if any input is "0".
American Standard Code for Information Interchange. ASCII is normally used when
alphanumeric (letters and decimal numbers) and control codes are sent as
information to printers, etc. ASCII can be represented using 7 or 8 bits and is often
expressed in a 2-digit hexadecimal form converted from specific binary expressions.
ASCII expressed in 2-digit hexadecimals is called "ASCII HEX code".
For details about actual ASCII codes, refer to the table for ASCII.
[EXAMPLE] When a letter "M" is expressed in ASCII code:
7-bit ASCII :
ASCII HEX code: 4D (hexadecimal)
Not synchronous. Repeated operations that take place in patterns unrelated over
time.
See American Wire Gauge (AWG).
A printed circuit board located in the back of a chassis, that contains a data bus, power
bus, and mating connectors for units. For FP3, FP5, FP10S and FP10 programmable
controllers, two types of backplanes are available:
Master Backplane
Expansion Backplane
A device that is kept available to replace something that may fail during operation.
A battery or set of batteries that will provide power to the processor memory only
when system power is lost. FP3 CPU, FP10S CPU, and S-RAM type IC cards have
a battery backup system.
A condition that exists when the backup battery voltage drops low enough to require
battery replacement. For FP3 CPU, FP10S CPU, S-RAM and S-RAM/
Flash-EEPROM type IC cards, the ERROR LED turns ON.
Formally defined as the shortest pulse width in data communication. However,
usually used to refer to the number of binary bits transmitted per second (bps) during
serial data communication.
