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.

1.4 Setting Jumpers
If you use an interface other than RS-232 (default), you must change the jumper
configuration to select the interface you wish to use. There are three jumpers
located at the bottom of the module.
The following illustration shows the MVI56-DNP jumper configuration:
1 Set the PRT 2 (for application port 1) and PRT 3 (for application port 2)
jumpers select RS232, RS422, or RS485 to match the wiring needed for your
application. The default jumper setting for both application ports is RS-232.
2 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 Installing the Module in the Rack
If you have not already installed and configured your ControlLogix processor and
power supply, please do so before installing the MVI56-DNP 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 MVI56-DNP into the
ControlLogix chassis. Use the same technique recommended by Rockwell
Automation to remove and install ControlLogix modules.
Warning: When you insert or remove the module while backplane power is on, an electrical arc
can occur. This could cause an explosion in hazardous location installations. Verify that power is
removed or the area is non-hazardous before proceeding. Repeated electrical arcing causes
excessive wear to contacts on both the module and its mating connector. Worn contacts may
create electrical resistance that can affect module operation.
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.

1.7.3 Adding the Module in Your Project
This topic describes how to add the module to your RSLogix 5000 project.
Note: The RSLogix 5000 software should be in "off-line" mode to add the module to a project.
Although some newer versions of RSLogix 5000 may allow new modules to be added while in
"online" mode, it is always considered safer to add new modules off-line and test the new
configuration in a test system before putting the modified program online.
This process consists of the following general steps.
1 Add the module to the project I/O configuration.
2 Select the sample ladder logic version that matches your processor firmware
version number and use it as a starting point for a new project or for copying
components into an existing project.
(Example ladder logic files are provided on the CD-ROM shipped with the
module or may be downloaded from the ProSoft Technology Web site.)
3 Modify the example ladder logic to meet the needs of your application, if
necessary.
4 Download the ladder logic to the processor.
Note: If you are installing this module in an existing application, you can copy the necessary
elements from the example ladder logic into your application.
The ladder logic samples show how to process one data block for each
supported data type, as well as showing how to use all of the special functions
and control variables used by the module. Depending on the point counts you
configure for each data type in the DNP.CFG file, the sample ladder logic may or
may not have sufficient data transfer capacity.
If your application has higher point counts than what is supported in the sample
ladder, you can add additional rungs with logic similar to that shown to process
data for up to two additional data blocks for each supported data type.
To Copy the Sample Ladder Logic into a New or an Existing Project
1 Add the MVI56-DNP module to the project.
In the C
ONTROLLER ORGANIZATION window, select I/O CONFIGURATION and
click the right mouse button to open a shortcut menu. On the shortcut menu,

After completing the module setup, the Controller Organization list will display
the module’s presence. The data required for the module will be defined to
the application, and objects will be allocated in the Controller Tags data area.
The following is an example of the Controller Organization list:
5 In a separate instance of RSLogix 5000, open the version of the sample
ladder logic project that matches the firmware revision number of your
ControlLogix processor. This is so you may copy and paste from the sample
into your existing project. If you are starting a new project, simply open the
appropriate sample version, pick your controller model and rack size, and use
this as the starting point for your new project.
6 Add the User Defined Data Types for the module. Copy these data types
from the sample ladder logic into your project. The Controller Organization list
should display the User Defined Data Types shown in the following example:

7 Add all controller tags. The MVI56-DNP module DNPCfgStatus tag array
holds the module status data. The DNPData tag array holds all the DNP and
IED data for each data type. Other more specialized tags and tag arrays hold
data to be sent or received by the Special Functions supported by the module
as well as bits and words used for sample ladder logic flow control and
processing (control bits and words).

8 The last step is to add the ladder logic. If you are using the sample ladder
logic, you may need to adjust it to fit your application. If you are not using the
ladder example, copy the ladder logic from the sample into your application
and make any modifications which may be needed for your application.

1.7.4 Selecting the Slot Number for the Module
This sample application is for a module installed in Slot 1 in a ControlLogix rack.
The ladder logic uses the slot number to identify the module. If you are installing
the module in a different slot, you must update the ladder logic so that program
tags and variables are correct, and do not conflict with other modules in the rack.
To change the slot number
1 In the Controller Organization list, select the module and then click the right
mouse button to open a shortcut menu.
2 On the shortcut menu, choose P
Properties dialog box.

3 In the Slot
field, use the spinners on the right side of the field to select the slot
number where the module will reside in the rack, and then click OK.
RSLogix will automatically apply the slot number change to all tags, variables
and ladder logic rungs that use the MVI56-DNP slot number for computation.
