ASCII Short for American Standard Code for Information Interchange. ASCII is used to
code characters for output to printers and other external devices.
asynchronous execution Execution of programs and servicing operations in which program execution
and servicing are not synchronized with each other.
auto-decrement A process that can be used when addressing memory through index registers so
that the address in the register is automatically reduced by 1 before each use.
auto-increment A process that can be used when addressing memory through index registers so
that the address in the register is automatically increased by 1 after each use.
Auxiliary Area A PC data area allocated to flags and control bits.
auxiliary bit A bit in the Auxiliary Area.
Backplane A base to which Units are mounted to form a Rack. Backplanes provide a series
of connectors for these Units along with buses to connect them to the CPU and
other Units and wiring to connect them to the Power Supply Unit. Backplanes
also provide connectors used to connect them to other Backplanes.
back-up A copy made of existing data to ensure that the data will not be lost even if the
original data is corrupted or erased.
bank One of multiple sections of a storage area for data or settings. The EM Area is
divided into banks each of which is accessed using the same addresses, but dif-
ferent bank numbers.
BASIC A common programming language. BASIC Units are programmed in BASIC.
basic instruction A fundamental instruction used in a ladder diagram. See advanced instruction .
Basic Rack Any of the following Racks: CPU Rack, Expansion CPU Rack, or Expansion I/O
Rack.
BASIC Unit A CPU Bus Unit used to run programs in BASIC.
baud rate The data transmission speed between two devices in a system measured in bits
per second.
BCD Short for binary-coded decimal.
BCD calculation An arithmetic calculation that uses numbers expressed in binary-coded deci-
mal.
binary A number system where all numbers are expressed in base 2, i.e., numbers are
written using only 0’s and 1’s. Each group of four binary bits is equivalent to one
hexadecimal digit. Binary data in memory is thus often expressed in hexadeci-
mal for convenience.
binary calculation An arithmetic calculation that uses numbers expressed in binary.
binary-coded decimal A system used to represent numbers so that every four binary bits is numerically
equivalent to one decimal digit.
bit The smallest piece of information that can be represented on a computer. A bit
has the value of either zero or one, corresponding to the electrical signals ON
