Glossary
Floppy disk used to store information such as programs or I/O tables. The
data disk should be used in drive B of the FIT.
Allows for the connection of up to 32 PCs in a Net Link System where each is
contributing information to a common memory area. Data links may be estab-
lished in the LR and/or DM memory areas.
The process of checking for errors in a program.
The original condition of a function or system. For example, the FIT's default
condition is to start from its hard drive, but this default condition can be
changed so that it starts from a floppy disk drive.
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.
[E(lectrically) E(rasable) P(rogrammable) R(ead) O(nly) M(emory)] A type of
ROM in which stored data can be erased and reprogrammed. This is accom-
plished using a special control lead connected to the EEPROM chip and can
be done without having to remove the EEPROM chip from the device in
which it is mounted.
Electric 'static' that can disturb electronic communications. The 'snow' that
can appear on a TV screen is an example of the effects of electrical noise.
[E(rasable) P(rogrammable) R(ead) O(nly) M(emory)] A type of ROM in
which stored data can be erased, by ultraviolet light or other means, and re-
programmed.
An I/O Unit for a Package-type PC that provides more I/O points to the PC.
A general-purpose computer, usually quite similar to a business computer,
that is used in automated factory control.
A bit that is turned ON and OFF automatically by the system in order to pro-
vide status information.
A Special I/O Unit. A High Speed Counter Unit counts independently of the
PC's cycle time. This allows counting of very short, fast signals.
A computer that is used to transfer data to or receive data from a PC in a
Host Link system. The host computer is used for data management and
overall system control. Host computers are generally small personal or busi-
ness computers.
A computer that has similar architecture to, and is logically compatible with
an IBM PC/XT computer; and that can run software designed for that com-
puter.
A succession of instructions which begins with a load instruction at the left
bus bar and ends at a right bus bar.
