A communications method in which signals are sent over wire cable. Although
noise resistance and transmission distance can sometimes be a problem with
wire communications, they are still the cheapest and the most common, and per-
fectly adequate for many applications.
A Remote I/O Master Unit connected via 2-conductor wire cables.
A Remote I/O Slave Unit connected via 2-conductor wire cables.
A Slave Rack connected through a Wired Slave.
A Remote I/O Master System connected via 2-conductor wire cables.
A unit of data storage in memory that consists of 16 bits. All data areas consists
of words. Some data areas can be accessed only by words; others, by either
words or bits.
The location in memory where a word of data is stored. A word address must
specify (sometimes by default) the data area and the number of the word that is
being addressed.
The process of assigning I/O words and bits in memory to I/O Units and termi-
nals in a PC System to create an I/O Table.
See custom data area .
A part of memory containing work words/bits.
A bit in a work word.
The location is memory when data currently being worked with is stored.
A word that can be used for data calculation or other manipulation in program-
ming, i.e., a ‘work space’ in memory. A large portion of the IR area is always re-
served for work words. Parts of other areas not required for special purposes
may also be used as work words.
A switch used to write-protect the contents of a storage device, e.g., a floppy
disk. If the hole on the upper left of a floppy disk is open, the information on this
floppy disk cannot be altered.
A state in which the contents of a storage device can be read but cannot be al-
tered.
An I/O refresh process in which I/O status is refreshed when the voltage of an AC
power supply is at zero volts.
