Subject of this chapter
What's in this Chapter?
The TSXCUSBMBP communications adapter is designed to provide a bridge between a simple and inexpensive USB connection and a Modbus Plus Network. The device is a combination of hardware (TSXCUSBMBP) and software drivers (TSXCUSBMBP Driver and Virtual Serial Port) that operate together as a single entity.
The TSXCUSBMBP has its own Modbus Plus Node Address on the Modbus Plus network, which is set via the TSXCUSBMBP Driver software.
The TSXCUSBMBP provides two areas of functionality. The first one allows software applications using serial Modbus RTU communications to communicate on a highspeed Modbus Plus network. The second one provides diagnostic tools for a Modbus Plus network.

Overview
Modbus Plus Communication for Applications
Introduction Most Win32 applications that support serial Modbus communications can
communicate on a Modbus Plus network with the TSXCUSBMBP.
Virtual Serial Port (VSP)
Modbus Plus Communication­Process
A Virtual Serial Port (VSP) is used as the mechanism for redirecting communications from programs such as Concept, Unity, and ProWorx32 to the TSXCUSBMBP adapter. The VSP presents the same interface as a standard serial port to the software. As such it is indistinguishable from a physical serial port.
The Modbus Plus Communication process is described in the following table:
Stage Description
1 After the VSP is installed, it will create one serial port with the port reference (COM1-
COM12) defined in the TSXCUSBMBP Driver software.
2 When configuring the Modbus application software, this port reference for the VSP
is selected as the serial port for the application to use.
3 The TSXCUSBMBP Driver will then work like a Bridge Multiplexer to redirect serial
Modbus Plus messages onto a Modbus Plus network, but at a much faster rate since no serial communications are actually taking place.

Routing Table A routing table similar to that used by Modicon's BM85 Bridge Multiplexer is used to
associate Modbus Slave IDs with 5-byte Modbus Plus routing paths. This allows the application software to communicate with any Modbus Plus device within range on a Modbus Plus network.

Modbus Plus Network Diagnostics
TSXCUSBMBP The TSXCUSBMBP provides a diagnostic tool for Modbus Plus networks. It has the
same basic functionality as the MBPSTAT program but adds the ability to scan a complete Modbus Plus network.
TSXCUSBMBP Hardware
Description The TSXCUSBMBP consists of a box with a USB cable extending from one end for
connection to a PC, and a standard Modbus Plus DB9 connector on the other end for connection to a Modbus Plus network.
LEDs in the top cover of the device indicate the presence of power from the USB port and the status of the Modbus Plus connection. No external power supply is needed.

Installation Requirements
Installation Requirements list
Installation requirements are as follows:
z Microsoft Windows XP Operating System with Service Pack 2 or greater installed
(Windows 2000 with Service Pack 4 or greater can also be used on most computers),
z 1 MB free disk space, z at least 256 MB RAM, z at least one free USB port or a USB Hub supporting USB 1.1 or greater.
Upgrading From Previous Version
Introduction Currently, if a previous version of the TSXCUSBMBP Driver has been installed, the
Virtual Serial Port component of the driver must be manually uninstalled using
Device Manager before a new version can be installed.
How to uninstall the Virtual Serial Port?
These steps must be followed to uninstall the Virtual Serial Port from your system.
Step Action
1 Close any software applications using the TSXCUSBMBP Driver.
2 Exit the TSXCUSBMBP Driver by right clicking on the Icon at the bottom then
selecting Exit Driver.
3 Unplug the USB Modbus Plus Device from the USB port on the computer (or USB
Hub if using one).
4 Start up the Windows Device Manager.
On most systems, this is done by the following steps.
z Open Control Panel, System, Hardware, then Device Manager. z In Device Manager, left click on the + next to ABT Virtual Device. Virtual Serial
Port will now appear underneath ABT Virtual Device.
z Right click on Virtual Serial Port and select Uninstall. z When prompted, confirm the device removal. z After ABT Virtual Device disappears from the list, close the Device Manager.

Installing the TSXCUSBMBP Driver Software
Introduction The TSXCUSBMBP Driver must be installed before connecting the TSXCUSBMBP
device to the USB port.
How to install the TSXCUSBMBP Driver?
Use the following procedure to install the Driver software.
Step Action
1 Insert the CD-ROM labeled TSXCUSBMBP Driver into your CD-ROM drive.
2 The installation should begin automatically. If not, follow the procedure below to start
the installation manually.
z From the Start menu (Start button on Windows XP task bar), select Run z Type in D:\Setup.exe (if your CD-ROM drive is not D:, substitute the drive letter of
your CD-ROM drive) and press Ok.
3 Follow the on-screen instructions to complete the software installation.
4 The final step of the software installation will display a message window containing
instructions. Please read the instructions carefully.
Installing the TSXCUSBMBP Hardware
Introduction The TSX C USB MBP can be connected directly to a USB port on the PC or
through a USB Hub. The TSXCUSBMBP acquires power from the USB port or Hub, therefore no power connection is required.
Note: Do not connect the Modbus Plus network cable to the Modbus Plus port on the TSXCUSBMBP until after the Modbus Plus Node Address has been configured in the Driver Software. This will avoid the potential for duplicate Modbus Plus node addresses on your network.

How to install the TSXCUSBMBP Hardware
Use the following procedure to install the TSXCUSBMBP hardware.
Step Action
1 After installing the TSXCUSBMBP Driver software, insert the USB cable from the
TSXCUSBMBP into a USB port on the PC or into a USB Hub connected to the PC. Once the TSXCUSBMBP is connected to the PC or Hub, the Power LED on the TSXCUSBMBP will light. This indicates that the TSXCUSBMBP is getting power from the USB port or Hub.

Status of the Driver
What's in this Chapter?
The TSXCUSBMBP Driver is added to the Startup group during installation. After restarting the computer at the end of the hardware installation, the driver will automatically start and will continue to do so each time the computer is powered up or restarted.
If the TSXCUSBMBP Driver is ever removed from the Startup menu, you will need to start the driver manually by going to the Programs menu and selecting Schneider Electric then TSXCUSBMBP then TSXCUSBMBP Driver. The TSXCUSBMBP Driver allows for only one instance of it to run at any time, so starting it multiple times is not a concern.
When the TSXCUSBMBP Driver is running, an icon will appear in the system tray of the computer to indicate the status of the driver, as shown in the table below.
Icon Color Status of the driver
normal A TSXCUSBMBP was found.
red No TSXCUSBMBP was found.
yellow A TSXCUSBMBP was found, and is in the process of initializing and
connecting to a Modbus Plus network.
