All of the PCs that share the same part of the LR are in a PC Link System.
PC Link Subsystems exist within a PC Link System when one or more of the
PCs in the System has two PC Link Units mounted to it. If Subsystems exist,
the System is considered a Multilevel PC Link System.
A System in which PCs are connected through PC Link Units to enable them
to share common data areas, i.e., each of the PCs writes to certain words in
the LR area and receives the data of the words written by all other PC Link
Units connected in series with it.
The Unit used to connect PCs in a PC Link System.
With building-block PCs, all of the Racks and independent Units connected
directly to them up to, but not including the I/O devices. The limits of the PC
System on the upper end is the PC and the program in its CPU Unit and on
the lower end, I/O Units, Special I/O Units, Optical I/O Units, Remote Termi-
nals, etc.
Devices connected to a PC System to aid in system operation. Peripheral
devices include printers, programming devices, external storage media, etc.
Processing signals to and from peripheral devices, including refreshing, com-
munications processing, interrupts, etc.
Any of the Units in a PC Link system that share common data areas except
for the Polling Unit.
A method in which one element in a system monitors changes in the con-
tents of certain data words to maintain accurate records of the contents. In a
PC Link System, polling is performed by the polling unit to maintain common
data areas among PCs.
The PC Link Unit in a PC Link System that handles data transmissions to
maintain common data areas within the PCs. In a PC Link System, the pol-
ling unit always shares common data areas with the polled units.
A board onto which electrical circuits are printed for mounting into a computer or
electrical device.
A mode of operation that allows inputting and debugging of programs to be car-
ried out, but that does not permit normal execution of the program.
A computerized device that can accept inputs from external devices and gen-
erate outputs to external devices according to a program held in memory.
Programmable Controllers are used to automate control of external devices.
Although single-unit Programmable Controllers are available, building-block
Programmable Controllers are constructed from separate components. Such
Programmable Controllers are formed only when enough of these separate
components are assembled to form a functional assembly, i.e., there is no
one individual Unit called a PC.
The simplest form or programming device available for a PC. Programming
Consoles are available both as hand-held models and as CPU Unit-mounting
models.
A peripheral device used to input a program into a PC or to alter or monitor a
program already held in the PC. There are dedicated programming devices,
such as Programming Consoles, and there are non-dedicated devices, such
as a host computer.
