High-density I/O Units are designed to provide high-density I/O capability and
include Group 2 High-density I/O Units and Special I/O High-density I/O Units.
Special I/O Units are dedicated Units that are designed to meet specific needs.
These include some of the High-density I/O Units, 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 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
C200HS. 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 C200HS
Installation Guide. If a Link System is required, refer to the appropriate Sys-
tem Manual.
3. On paper, assign all input and output devices to I/O points on Units and de-
termine 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 sequence
of required operations and their inter-relationships. Be sure to also program
appropriate responses for all possible emergency situations. (Section 4
Writing and Inputting the Program, Section 5 Instruction Set, Section 6 Pro-
gram Execution Timing)
5. Input the program and all required operating parameters into the PC. (Sec-
tion 4-7 Inputting, Modifying, and Checking the Program.)
6. Debug the program, first to eliminate any syntax errors, and then to find ex-
ecution errors. (Section 4-7 Inputting, Modifying, and Checking the Pro-
gram, Section 7 Program Monitoring and Execution, and Section 10
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 C200HS Installation Guide
and to Operation Manuals and System Manuals for details on individual
Units.
8. Test the program in an actual control situation and carry out fine tuning as
required. (Section 7 Program Monitoring and Execution and Section 10
Troubleshooting)
9. Record two copies of the finished program on masters and store them safely
in different locations. (Section 4-7 Inputting, Modifying, and Checking the
Program)
Control System Design
Designing the Control System is the first step in automating any process. A PC
can be programmed and operated only after the overall Control System is fully
understood. Designing the Control System requires, first of all, a thorough un-
derstanding of the system that is to be controlled. The first step in designing a
Control System is thus determining the requirements of the controlled system.
