Appendix 7 Communication Support Tool (MX Component)

MELSEC-Q

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.

<Example of communication using MX Component>

MELSECNET/H communication

Ethernet communication

Modem communication

GOT

Gateway function communication

(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.
