About this Manual:

This manual describes the function blocks and related functionality of the CX-Programmer Ver. 5.0

used together with CS1-H, CJ1-H, and CJ1M CPU Units with unit version 3.0 or later, and includes the

sections described on the next page. The CX-Programmer Ver. 5.0 is software that enables the per-

sonal computer to be used as a function block programming device, and can be used only for SYS-

MAC CS-series and CJ-series CPU Units that support function blocks.

The CX-Programmer Ver. 5.0 function block functions have been enhanced. This manual describes

only CX-Programmer Ver. 5.0 operations that are related to functions blocks. For operations not related

to function blocks, refer to the CX-Programmer Operation Manual (enclosed, Cat. No. W437). This

manual also provides only information related to function blocks for the CS1-H, CJ1-H, and CJ1M CPU

Units. For other information, refer to the CS/CJ-series manuals.

Please read this manual and related manuals carefully and be sure you understand the information

provided before attempting to install or operate the CX-Programmer Ver. 5.0 or the CS1-H, CJ1-H, or

CJ1M CPU Units. Be sure to read the precautions provided in the following section.
