Duplex Unit
A number system where all numbers are expressed to the base 10. Although
in a PC all data is ultimately stored in binary form, four binary bits are often
used to represent one decimal digit, via a system called binary-coded deci-
mal.
Decreasing a numeric value.
A value assumed and automatically set by the PC when a specific value is
not input by the user. Many devices will assume such default conditions upon
the application of power.
A number used as an operand for an instruction but that serves to define the
instruction itself rather that the data on which the instruction is to operate.
Definers include jump numbers, subroutine numbers, etc.
A carriage return (CR) indicating the end of the current frame within a mul-
ti-frame block of information. A terminator indicates the end of the block.
The location where data in an instruction is to be placed, as opposed to the
location from which data is to be taken, for use in the instruction. The location
from which data is to be taken is called the source.
An instruction that is executed only once each time its execution condition
goes from OFF to ON. Nondifferentiated instructions are executed each cycle
as long as the execution condition stays ON.
An instruction used to ensure that the operand bit is never turned ON for
more than one cycle after the execution condition goes either from OFF to
ON for a Differentiate Up instruction or from ON to OFF for a Differentiate
Down instruction.
A unit of storage in memory that consists of four bits.
An operand that is used to designate the digit or digits of a word to be used
by an instruction.
An automation concept in which control of each portion of an automated sys-
tem is located near the devices actually being controlled, i.e., control is de-
centralized and ‘distributed’ over the system. Distributed control is a concept
basic to PC Systems.
A data area used to hold word data. A word in the DM area cannot be ac-
cessed bit by bit.
The process of transferring a program or data from a higher-level computer
to a lower-level computer or PC.
A CPU arrangement available for a C2000H PC in which there is actually two
CPUs. Each of the CPUs holds the same program and the same data. One
of the CPUs is active and controls current PC operation; the other CPU
serves as a backup and takes over PC operation if the active CPU fails.
A C2000H PC System that uses a Duplex CPU.
The Unit that coordinates the CPU activities of a Duplex System.
