Battery Life Advisory

The MVI46, MVI56, MVI56E, MVI69, and MVI71 modules use a rechargeable Lithium Vanadium Pentoxide battery to
backup the 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 the battery becomes fully charged. After it is fully charged, the battery
provides backup power for the CMOS setup and the real-time clock for approximately 21 days. When the battery is
fully discharged, the module will revert to the default BIOS and clock settings.

Note: The battery is not user replaceable.

1.3 Setting Jumpers

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.

The following illustration shows the MVI71-DFNT jumper configuration.

Note: If you are installing the module in a remote rack, you may prefer to leave the Setup pins
jumpered. That way, you can update the module’s firmware without requiring physical access to
the module.

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-DFNT 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.

User Manual EtherNet/IP Client/Server Communication Module

The rest of this chapter describes these steps in more detail.
Set up of the MVI71-DFNT module requires software configuration using the

RSLogix 5 program and the DFNT.CFG file on the Compact Flash Disk in the
module. The easiest method to implement the module is to start with the
appropriate example provided with the module MVI71DFNT_BT.RSP for the
block transfer interface and the default configuration file. If you are installing this
module in an existing application, you can copy the elements required from the
example ladder logic to your application.

It is now time to edit the DFNT.CFG file to set up the module for the specific
application. Refer to the Configuration File section of this document. Download
this configuration to the module along with the associated ladder logic.

Enter the ladder logic to handle the blocks transferred between the module and
the PLC. Download the program to the PLC and test the program with the
module.

The module is now set up and ready for your application. Insert the module in the
rack (with the power turned off) and attach the serial communication cables.
Download the new application to the controller and place the processor in run
mode. Download the new DFNT.CFG file to the module using a terminal
emulation program. If all the configuration parameters are set correctly and the
module is attached to a network, the module’s Application LED (APP LED)
should remain off and the backplane activity LED (BP ACT) should blink very
rapidly. Refer to Diagnostics and Troubleshooting if you encounter errors. Attach
a computer or terminal to Port 0 on the module and look at the status of the
module using the Configuration/Debug Menu in the module.

2.1 Module Configuration

This section contains the setup procedure, data, and ladder logic for successful
application of the MVI71-DFNT module. Each step in the setup procedure is
defined in order to simplify the use of the module.

2.1.1 Obtain the Sample Configuration Files

The ProSoft Solutions CD is organized in folders by module name. In the folder
for the module you are using, you will find sample configuration files and other
information.

1 Use Windows Explorer to locate the sample configuration files for your MVI71

module on the MVI71 CD.

2 When you have located the correct configuration files, use the C

P

ASTE commands to move the files to a location on your PC’s hard drive. We

recommend C:\temp.

2.2 Configuration File

In order for the module to operate, a configuration file (DFNT.CFG) is required.
This configuration file contains information to set the data transfer characteristics
between the module and the processor, to configure the module's client and
command list, and to configure the pass-through features. Each parameter in the
file must be set carefully in order for the application to be implemented
successfully.

The configuration file is separated into sections with topic header names
enclosed in the [ ] characters. The configuration file consists of the following
sections:

[Section] Description

[Module] General module configuration information
[DFNT Client 0] Configuration for the DFNT client
[DFNT Client 0 Commands] Command list for the DFNT client
[DF1 Pass-Through Server Port 1] Parameters for the pass-through port of the second port

[DF1 Pass-Through Port] Parameters for the DF1 port emulated on the third port of

After each section header, the file contains a set of parameters. Unique labels
are used under each section to specify a parameter. Each label in the file must
be entered exactly as shown in the file for the parameter to be identified by the
program. If the module is not considering a parameter, look at the label for the
data item. Each parameter's value is separated from the label with the ":"
character. This character is used by the program to delimit the position in the
data record where to start reading data. All data for a parameter must be placed
after the ":" character. For numeric parameter values any text located after the
value will not be used. There must be at least one space character between the
end of the parameter value and the following text.

Any record that begins with the "#" character is considered to be a comment
record. These records can be placed anywhere in the file as long as the "#"
character is found in the first column of the line. These lines are ignored in the
file and can be used to provide documentation within the configuration file.
Liberal use of comments within the file can ease the use and interpretation of the
data in the file.

The client command list section is formatted differently than the other sections.
These sections contain lists of parameters to be used. Each list begins with the
label START and when the END label is reached. When entering the records into
the list, make certain that the first character in each line is left blank.

The [DFNT CLIENT 0 COMMANDS] section defines the Ethernet/IP commands
to be issued from the module to server devices on the network. These
commands can be used for data collection and/or control of devices on the
TCP/IP network.
