OMRON Product Terminology
OMRON products are divided into several functional groups that have ge-
neric names. Appendix A Standard Models list products according to these
groups. The term Unit is used to refer to all of the OMRON PC products. Al-
though a Unit is any one of the building blocks that goes together to form a
C200H PC, its meaning is generally, but not always, limited in context to refer
to the Units that are mounted to a Rack. Most, but not all, of these products
have names that end with the word Unit.
The largest group of OMRON products is the I/O Units. These include all of
the Rack-mounting Units that provide non-dedicated input or output points for
general use. I/O Units come with a variety of point connections and specifica-
tions.
Special I/O Units are dedicated Units that are designed to meet specific
needs. These include Position Control Units, High-speed Counter Units, and
Analog I/O Units.
Link Units are used to create Link Systems that link more than one PC or
link a single PC to remote I/O points. Link Units include Remote I/O Units, PC
Link Units, Host Link Units, SYSMAC NET Link Units, and SYSMAC LINK
Units. SYSMAC NET Link and SYSMAC LINK Units can be used with the
CPU11-E only.
Other product groups include Programming Devices, Peripheral Devices,
and DIN Rail Products.

Overview of PC Operation
The following are the basic steps involved in programming and operating a
C200H. Assuming you have already purchased one or more of these PCs,
you must have a reasonable idea of the required information for steps one
and two, which are discussed briefly below. This manual is written to explain
steps three through six, eight, and nine. The relevant sections of this manual
that provide more information are listed with each of these steps.
1, 2, 3... 1.
Determine what the controlled system must do, in what order, and at
what times.
2.
Determine what Racks and what Units will be required. Refer to the
C200H Installation Guide. If a Link System is required, refer to the ap-
propriate System Manual.
3.
On paper, assign all input and output devices to I/O points on Units and
determine which I/O bits will be allocated to each. If the PC includes
Special I/O Units or Link Systems, refer to the individual Operation
Manuals or System Manuals for details on I/O bit allocation. (Section 3
Memory Areas)
4.
Using relay ladder symbols, write a program that represents the se-
quence of required operations and their inter-relationships. Be sure to
also program appropriate responses for all possible emergency situ-
ations. (Section 4 Writing ana Inputting the Program, Section 5 Instruc-
tion Set, Section 6 Program Execution Timing)
5.
Input the program and all required operating parameters into the PC.
(Section 4-6 Inputting, Modifying, and Checking the Program.)
6.
Debug the program, first to eliminate any syntax errors, and then to find
execution errors. (Section 4-6 Inputting, Modifying, and Checking the
Program , Section 7 Program Monitoring and Execution, and Section 8
Troubleshooting)
7.
Wire the PC to the controlled system. This step can actually be started
as soon as step 3 has been completed. Refer to the C200H Installation
