Introduction - Omron WIRED REMOTE I-O System Manual

About this Manual:
This manual describes the means and Units necessary to construct a Wired Remote I/O System con-
sisting of at least one Remote I/O Master Unit and one or more Remote I/O Slave Units or Remote
Terminals. (The term "Wired" refers to the links used to create the Remote I/O System, e.g., that be-
tween a Remote I/O Master Unit and a Remote I/O Slave Unit.) Remote I/O Systems reduce wiring
requirements for remote control from a PC by performing distributed control actions through execution
of a program in the memory of a single PC's CPU. The 3G2A5-RM201 Remote I/O Master Unit can
be used with any C-series Rack PC except the C200H PC. The C200H-RM201 Remote I/O Master
Unit is used with a C200H PC. Remote I/O Slave Units, though generally used with the corresponding
Remote I/O Master Unit, can be used in "combined" system configurations.
This manual has been prepared to explain how to incorporate Wired Remote I/O Systems into C120,
C500, C200H, C1000H, and C2000H PC Systems. It provides the necessary information, such as
system configuration, settings, and I/O word allocation, for connecting Remote I/O Master Units, Re-
mote I/O Slave Units, and I/O Units.
Before attempting to set up and operate your Remote I/O System, familiarize yourself with all relevant
parts of this manual. For more detailed descriptions of manual content, refer to the introductions for
individual sections.
Section 1 introduces Wired I/O Systems and describes their characteristics.
Section 2 describes some of the many possible system configurations and the limitations of each
type of system.
Section 3 provides names and descriptions of basic functions, internal circuits, and methods for dif-
ferentiating differentiating unit types. Settings required to operate the system and successfully com-
municate program actions are explained, and example system settings are provided.
Section 4 provides details on Wired Remote I/O Systems, and the main Units used to build these
Systems, included within these are mounting restrictions and wiring considerations of the systems.
Parts of the Units, switch setting, and examples of switch settings are provided.
Section 5 explains how to install Wired I/O Systems and includes information on dimensions, differ-
ences between Units, and wiring.
Section 6 offers details on response time computations.
Section 7 describes error indications and error processing. Both indicator lights and dedicated error-
related flags are provided.
Appendix A provides a list of the basic specifications and complete model numbers of products used
in Wired I/O Systems.
Appendix B provides technical specifications.
Appendix C provides information on using CS1-series PCs.
