Appendix 7 Communication Support Tool (MX Component)
MX Component is an ActiveX control library that supports any types of communication
paths between IBM PC/AT compatible personal computers and PLCs. It allows the
users to establish communication using simple processing only, without having to
know about the different communication protocols used in the individual
communication.
It also supports various programming languages, allowing for a wide range of
application development.
This section provides the overview of the functions provided by MX Component and
explains the procedure up to creation of applications.
See Operating Manual and Programming Manual of MX Component for the details.
Appendix 7.1 Overview of MX Component
This section provides the overview of MX Component.
Different communication paths, operating systems, programming languages, and
functions are supported depending on the version of MX Component used.
(1) Support for a wide range of communication paths to PLCs
MX Component supports a wide range of communication paths to PLCs. It is
possible to construct systems according to the needs of the users.

(2) Dramatic improvement of application development efficiency
MX Component provides wizard-style communication setting utilities.
The user only needs to select settings from menus displayed on the screen in an
interactive manner to achieve the communication settings required to access the
target PLC CPU.
Moreover, once the communication setting has been performed, it is possible to
access the PLC CPU simply by specifying the logical station number that is
stored via the communication setting utilities.
