This document aims to explain the wiring methods and communications settings
necessary to connect the corresponding devices and provide the setting
procedures. The program used in this document is designed to check if the
connection was properly established and is not designed to be constantly used
at a site. Therefore, functionality and performances are not sufficiently taken
into consideration.
When you construct an actual system, please use the wiring methods,
communications settings, and setting procedures described in this document as
a reference and design a new program according to your application needs.
