Unit
A Unit that mounts to a Backplane in a Rack PC. It provides power at the voltage
required by the other Units on the Rack.
A small, computer-like device that can control peripheral equipment, such as an
electric door or quality control devices, based on programming and peripheral
input devices. Any process that can be controlled using electrical signals can be
controlled by a PC. PCs can be used independently or networked together into a
system to control more complex operations.
[P(rogrammable) R(ead) O(nly) M(emory)] A type of ROM into which the pro-
gram or data may be written after manufacture, by a customer, but which is fixed
from that time on.
A PROM Writer is a device used to write data to ROM, PROM, and EPROM stor-
age chips.
An assembly that forms a functional unit in a Rack PC System. A Rack consists
of a Backplane and the Units mounted to it. These Units include the Power Sup-
ply, CPU, and I/O Units. Racks include CPU Racks, Expansion I/O Racks, and
I/O Racks. The CPU Rack is the Rack with the CPU mounted to it. An Expansion
I/O Rack is an additional Rack that holds extra I/O Units. An I/O Rack is used in
the C2000H Duplex System, because there is no room for any I/O Units on the
CPU Rack in this System.
A PC that is composed of Units mounted to one or more Racks. This configura-
tion is the most flexible, and most large PCs are Rack PCs. A Rack PC is the
opposite of a Package-type PC, which has all of the basic I/O, storage, and con-
trol functions built into a single package.
[R(andom) A(ccess) M(emory)] RAM will not retain data when power is discon-
nected. Therefore data should not be stored in RAM.
A Unit that extends the distance an Expansion I/O Rack can be from the CPU.
[R(ead) O(nly) M(emory)] A type of digital storage that cannot be written to. A
ROM chip is manufactured with its program or data already stored in it, and it can
never be changed. However, the program or data can be read as many times as
desired.
A C2000H PC that operates using one CPU mounted to the CPU Rack.
A Unit mounted to the I/O Backplane of a C2000H Duplex System that simply fills
the space between the I/O Expansion Power Supply and the rightmost Unit
mounted on the Rack.
A dedicated Unit that is designed for a specific purpose. Special I/O Units in-
clude Position Control Units, High-Speed Counters, Analog I/O Units, etc.
The arrangement in which Units in a System are connected. This term refers to
the conceptual arrangement and wiring together of all the devices needed to
comprise the System. In OMRON terminology, system configuration is used to
describe the arrangement and connection of the Units comprising a Control Sys-
tem that includes one or more PCs.
In OMRON PC terminology, the word Unit is capitalized to indicate any product
sold for a PC System. though most of the names of these products end with the
word Unit, not all do, e.g., a Remote Terminal is referred to in a collective sense
as a Unit. Context generally makes any limitations of this word clear.
