USER MANUAL

Please Read This Notice
Successful application of this module requires a reasonable working knowledge of the Rockwell Automation PLC
hardware, the MVI71-N2 Module and the application in which the combination is to be used. For this reason, it is
important that those responsible for implementation satisfy themselves that the combination will meet the needs of
the application without exposing personnel or equipment to unsafe or inappropriate working conditions.
This manual is provided to assist the user. Every attempt has been made to ensure that the information provided is
accurate and a true reflection of the product's installation requirements. In order to ensure a complete understanding
of the operation of the product, the user should read all applicable Rockwell Automation documentation on the
operation of the Rockwell Automation hardware.
Under no conditions will ProSoft Technology be responsible or liable for indirect or consequential damages resulting
from the use or application of the product.
Reproduction of the contents of this manual, in whole or in part, without written permission from ProSoft Technology
is prohibited.
Information in this manual is subject to change without notice and does not represent a commitment on the part of
ProSoft Technology Improvements and/or changes in this manual or the product may be made at any time. These
changes will be made periodically to correct technical inaccuracies or typographical errors.
Warning: This module is not hot-swappable! Always remove power from the rack before inserting or removing this
module, or damage may result to the module, the processor, or other connected devices.
Power, Input, and Output (I/O) wiring must be in accordance with Class 1, Division 2 wiring
methods, Article 501-4 (b) of the National Electrical Code, NFPA 70 for installation in the U.S.,
or as specified in Section 18-1J2 of the Canadian Electrical Code for installations in Canada,
and in accordance with the authority having jurisdiction.
A Warning - Explosion Hazard - Substitution of components may impair suitability for Class 1, Division 2.
B Warning - Explosion Hazard - When in hazardous locations, turn off power before replacing or wiring modules.
C Warning - Explosion Hazard - Do not disconnect equipment unless power has been switched off or the area is
known to be non-hazardous.

Battery Life Advisory
All modules in the MVI series use a rechargeable Lithium Vanadium Pentoxide battery to backup the 512K SRAM
memory, real-time clock, and CMOS. The battery should last for the life of the module.
The module must be powered for approximately twenty hours before it becomes fully charged. After it is fully charged,
the battery provides backup power for the CMOS setup and configuration data, the real-time clock, and the 512K
SRAM memory for approximately 21 days.
Before you remove a module from its power source, ensure that the battery within the module is fully charged. A fully
charged battery will hold the BIOS settings (after being removed from its power source) for a limited number of days.
When the battery is fully discharged, the module will revert to the default BIOS settings.
Note: The battery is not user replaceable.

To install ProSoft Configuration Builder from the ProSoft Web Site
1 Open your web browser and navigate to http://www.prosoft-
technology.com/pcb
2 Click the Download Here link to download the latest version of ProSoft
Configuration Builder.
3 Choose "Save" or "Save File" when prompted. The following illustrations
show the file download prompt for two of the most common web browsers.
4 Make a note of the location where you saved the file, for example "Desktop",
or "My Documents", so you can start the installation program.
5 When the download is complete, locate and open the file, and then follow the
instructions on your screen to install the program.
If you do not have access to the Internet, you can install ProSoft Configuration
Builder from the ProSoft Solutions CD-ROM, included in the package with your
MVI71-N2 module.

3 Click to open the Utilities folder. This folder contains all of the applications
and files you will need to set up and configure your module.
4 Double-click the ProSoft Configuration Builder Setup program and follow the
instructions on your screen to install the software on your PC.
Note: Many of the configuration and maintenance procedures use files and other utilities on the
CD-ROM. You may wish to copy the files from the Utilities folder on the CD-ROM to a convenient
location on your hard drive.
1.4 Setting Jumpers
The following illustration shows the jumper configurations for the various RS
interfaces. If you are using an interface other than RS-232 (default), you must
change the jumpers as shown:
The Setup Jumper acts as "write protection" for the module's flash memory. In
"write protected" mode, the Setup pins are not connected, and the module's
firmware cannot be overwritten. Do not jumper the Setup pins together unless
you are directed to do so by ProSoft Technical Support.

1.5 Install the Module in the Rack
If you have not already installed and configured your PLC processor and power
supply, please do so before installing the MVI71-N2 module. Refer to your
Rockwell Automation product documentation for installation instructions.
Warning: You must follow all safety instructions when installing this or any other electronic
devices. Failure to follow safety procedures could result in damage to hardware or data, or even
serious injury or death to personnel. Refer to the documentation for each device you plan to
connect to verify that suitable safety procedures are in place before installing or servicing the
device.
After you have checked the placement of the jumpers, insert MVI71-N2 into the
PLC™ chassis. Use the same technique recommended by Rockwell Automation
to remove and install PLC modules.
Warning: This module is not hot-swappable! Always remove power from the rack before
inserting or removing this module, or damage may result to the module, the processor, or other
connected devices.
1 Turn power OFF.
2 Align the module with the top and bottom guides, and slide it into the rack
until the module is firmly against the backplane connector.
3 With a firm but steady push, snap the module into place.

4 Check that the holding clips on the top and bottom of the module are securely
in the locking holes of the rack.
5 Make a note of the slot location. You will need to identify the slot in which the
module is installed in order for the sample program to work correctly. Slot
numbers are identified on the green circuit board (backplane) of the PLC
rack.
6 Turn power ON.
Note: If you insert the module improperly, the system may stop working, or may behave
unpredictably.
1.6 Connect your PC to the Processor
1 Connect the right-angle connector end of the cable to your controller at the
communications port.

1.7.1 Configuring RSLinx
If RSLogix is unable to establish communication with the processor, follow these steps:
1 Open RSLinx.
2 Open the Communications menu, and choose Configure Drivers.
This action opens the Configure Drivers dialog box.
Note: If the list of configured drivers is blank, you must first choose and configure a driver from the
Available Driver Types list. The recommended driver type to choose for serial communication with
the processor is "RS-232 DF1 Devices".
