The purpose of this document is to describe the wiring methods, communication
settings, and setting procedures required to establish a connection for
communications with applicable devices. In addition, the program used in this
document is designed to check that the connection has been correctly
performed (connection check). Since the program is not intended for permanent
use on-site, full consideration is not given to functionality and performance.
When configuring an actual system, please refer to the wiring methods,
communication settings, and setting procedures described in this document to
design and create a program that meets your purpose.
