About this Manual:A PC Link System enables use of the LR (Link Relay) data area as a common data area shared by all PCs
in the PC Link System, thus simplifying programming, settings, and data exchange between PCs and per-
mitting effective use of inputs and outputs.
This manual has been written to provide the information necessary to design and install a single-level or
multilevel PC Link System using PC Link Units with C500, C500F, C1000H, C2000, C2000H, C200H,
C200HS, and/or C200HX/HG/HE(-Z) PCs. Before attempting to design, install, or operate a PC Link Sys-
tem, be sure to thoroughly familiarize yourself with the information contained herein. During operation,
refer to the relevant PC Programming Manuals for programming and control system details.
Section 1 introduces PC Link Systems and describes their advantages and characteristics. It also
describes the improvements made in the most recent version.
Section 2 describes the elements that go together to construct a PC Link System and the factors re-
quired to design a System.
Section 3 describes the LR area used in data transfer between the PCs, the method used to allocate
it to the PCs, and the polling process used to actually transfer data.
Section 4 provides details on PC Link Units, the main Units used to build PC Link Systems. Parts of
the Units, switch setting, and examples of switch settings are provided.
Section 5 provides details on mounting and wiring PC Link Units and provides Unit dimensions.
Section 6 offers details and examples of programming PCs to utilize PC Link Systems effectively.
Section 7 describes error indications and error processing. Both indicator lights and dedicated error-
related flags are provided.
Section 8 describes basic maintenance and hardware troubleshooting procedures.
Appendix A provides basic specifications and complete model numbers for OMRON products used
in PC Link Systems.
Appendix B provides general specifications for PC Link Units and PC Link Systems.
This manual is intended to be used in conjunction with the PC Operation Manual and/or Installation
Guides for the PCs in the System. In most Systems, the Link Adaptor Operation Guide will also be
required. The application of Link Adaptors to PC Link Systems is also described in this manual.
This manual is designed for the C500-LK009-V1 and C200H-LK401 PC Link Units. These are some-
times referred to as the LK009-V1 and LK401. The older 3G2A5-LK003-E and 3G2A5-LK009-E PC
Link Units are mentioned only to allow combination with the newer models, and are not discussed in
detail.
