Introduction
This section gives a brief overview of the history of Programmable Controllers and explains terms commonly used in
ladder-diagram programming. It also provides an overview of the process of programming and operating a PC and ex-
plains basic terminology used with OMRON PCs. Descriptions of peripheral devices used with the C200H, and a table of
other manuals available to use with this manual for special PC applications, are also provided.
