Execution of programs and servicing operations in which program execution
and servicing are not synchronized with each other.
A PC data area allocated to flags and control bits.
A bit in the Auxiliary Area.
A copy made of existing data to ensure that the data will not be lost even if the
original data is corrupted or erased.
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.
A common programming language. BASIC Units are programmed in BASIC.
A fundamental instruction used in a ladder diagram. See advanced instruction .
Any of the following Racks: CPU Rack, Expansion CPU Rack, or Expansion I/O
Rack.
A CPU Bus Unit used to run programs in BASIC.
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 with-
in the word.
A number that indicates the location of a bit within a word. Bit 00 is the rightmost
(least-significant) bit; bit 15 is the leftmost (most-significant) bit.
See logic block and instruction block .
A comment placed in a ladder diagrams that provides user information on an in-
struction block.
In SFC programs, a means of controlling program flow so that one step leads to
two or more steps. See conditional branch and parallel branch .
A temporary storage space for data in a computerized device.
