Omron SYSMAC C2000H Operation Manual page 9

About this Manual:
The OMRON C1000H and C2000H offer an effective way to automate processing. Manufacturing,
assembly, packaging, and many other processes can be automated to save time and money. Distrib-
uted control systems can also be designed to allow centralized monitoring and supervision of several
separate controlled systems. Monitoring and supervising can be done through a host computer, con-
necting the controlled system to a data bank. It is thus possible to have adjustments in system opera-
tion made automatically to compensate for requirement changes.
The C1000H and C2000H are Rack PCs, i.e., various Units are combined to produce the optimum
control system for each application, which can just as easily be expanded up to the maximum I/O ca-
pacity of the PC by adding additional Units in the future. Additional Units include dedicated Special
I/O Units that can be used for specific tacks and Link Units that can be used to build more highly inte-
grated systems, including an optical LAN.
The C1000H and C2000H are equipped with large programming instruction sets, data areas, and
other features to control processing directly or remotely. Programming utilizes ladder-diagram pro-
gramming methods, which are described in detail for those unfamiliar with them.
This manual describes the characteristics and abilities of the C1000H and C2000H, programming op-
erations and instructions, and other aspects of operation and preparation that demand attention. Be-
fore attempting to operate the PC, thoroughly familiarize yourself with the information contained
herein. Hardware information is provided in detail in the C1000H/C2000H Installation Guide. A table
of other manuals that can be used in combination with this manual is provided at the end of Section 1
Introduction.
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
explains basic terminology used with OMRON PCs. Descriptions of peripheral devices used with the
C1000H and C2000H 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
information provided there to aid in programming. It also explains how I/O is managed in memory and
how bits in memory correspond to specific I/O points.
Section 4 Writing and Inputting the Programming explains the basics of ladder-diagram program-
ming and how the program is input into the PC using a Programming Console. The elements that
make up the 'ladder' part of a ladder-diagram program and how execution of this program is con-
trolled are explained. The user should be able to write and input a basic "input-output" program after
finishing this section.
Section 5 Instruction Set then goes on to describe individually all of the instructions used in pro-
gramming.
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 provides the Programming Console procedures
used to debug the program and to monitor and control operation.
Finally, Section 8 Troubleshooting provides information on error indications and other means of re-
ducing down time. Information in this section is also sometimes necessary when debugging a pro-
gram.
The appendices provide tables of standard OMRON products available for the C1000H and C2000H,
reference tables of instructions and Programming Console operations, and other information helpful in
PC operation.
