building-block PC
A number used to identify the location of data or programming instructions in
memory or to identify the location of a node on a network.
All-glass optical fiber cable; also known as crystal optical fiber cable.
The process by which the PC assigns certain bits or words in memory for various
functions. This includes pairing I/O bits to I/O points on Units.
An acronym for all-plastic optical fiber cable.
A PC data area allocated to flags and control bits.
A bit in the Auxiliary Area.
A base to which Units are mounted to form a Rack. Backplanes provide a
series of connectors for these Units along with wiring to connect them to the
CPU Unit. Backplanes also provide connectors used to connect them to other
Backplanes. In some Systems, different Backplanes are used for different
Racks; in other Systems, Racks differ only by the Units mounted to them.
A control system that includes only one of the following systems: SYSMAC
LINK System, Remote I/O System, PC Link System, Host Link System, or
NET Link System.
The data transmission speed between two devices in a system measured in bits
per second.
Short for binary-coded decimal.
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.
A system used to represent numbers so that every four binary bits is numerically
equivalent to one decimal digit.
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
and OFF. A bit represents one binary digit. Some bits at particular addresses are
allocated to special purposes, such as holding the status of input from external
devices, while other bits are available for general use in programming.
The location in memory where a bit of data is stored. A bit address specifies the
data area and word that is being addressed as well as the number of the bit
within the word.
A temporary storage space for data in a computerized device.
A PC that is constructed from individual components, or “building blocks.”
With building-block PCs, there is no one Unit that is independently identifi-
able as a PC. The PC is rather a functional assembly of components.
