About this Manual:
This manual describes the operation of the C200HS C-series Programmable Controllers, and it includes
the sections described below. Installation information is provided in the
C200HS Programmable Control-
ler Installation Guide
. A table of other manuals that can be used in conjunction with this manual is provided
in
Section 1 Introduction
. Provided in
Section 2 Hardware Considerations
is a description of the differ-
ences between the older CPUs and the new CPUs described in this manual.
Please read this manual completely and be sure you understand the information provided before attempt-
ing to operate the C200HS. Be sure to read the precautions in the following section.
Section 1 Introduction
explains the background and some of the basic terms used in ladder-diagram
programming. It also provides an overview of the process of programming and operating a PC and ex-
plains basic terminology used with OMRON PCs. Descriptions of Peripheral Devices used with the
C200HS PCs and a table of other manuals available to use with this manual for special PC applications
are also provided.
Section 2 Hardware Considerations
explains basic aspects of the overall PC configuration and de-
scribes the indicators that are referred to in other sections of this manual.
Section 3 Memory Areas
takes a look at the way memory is divided and allocated and explains the infor-
mation provided there to aid in programming. It explains how I/O is managed in memory and how bits in
memory correspond to specific I/O points. It also provides information on System DM, a special area in
C200HS PCs that provides the user with flexible control of PC operating parameters.
Section 4 Writing and Entering Programs
explains the basics of ladder-diagram programming, looking
at the elements that make up the parts of a ladder-diagram program and explaining how execution of this
program is controlled. It also explains how to convert ladder diagrams into mnemonic code so that the
programs can be entered using a Programming Console.
S
ection 5 Instruction Set
describes all of the instructions used in programming.
Section 6 Program Execution Timing
explains the cycling process used to execute the program and
tells how to coordinate inputs and outputs so that they occur at the proper times.
Section 7 Program Debugging and Execution
explains the Programming Console procedures used to
input and debug the program and to monitor and control operation.
Section 8 Communications
provides an overview of the communications features provided by the
C200HS.
Section 9 Memory Cassette Operations
describes how to manage both UM Area and IOM data via
Memory Cassettes. mounted in the CPU.
Section 10 Troubleshooting
provides information on error indications and other means of reducing down-
time. Information in this section is also useful when debugging programs.
Section 11 Host Link Commands
explains the methods and procedures for using host link commands,
which can be used for host link communications via the C200HS ports.
The
Appendices
provide tables of standard OMRON products available for the C200HS PCs, reference
tables of instructions and Programming Console operations, coding sheet to help in programming and
parameter input, and other information helpful in PC operation.
WARNING Failure to read and understand the information provided in this manual may result in
personal injury or death, damage to the product, or product failure. Please read each
section in its entirety and be sure you understand the information provided in the section
and related sections before attempting any of the procedures or operations given.
