Battery Life Advisory

Note: Modules manufactured after April 1st, 2011 do not contain a battery. For modules manufactured before that
date the following applies:

The module uses a rechargeable Lithium Vanadium Pentoxide battery to back up the real-time clock and CMOS
settings. The battery itself should last for the life of the module. However, if left in an unpowered state for 14 to 21
days, the battery may become fully discharged and require recharging by being placed in a powered-up ControlLogix
chassis. The time required to fully recharge the battery may be as long as 24 hours.

Once it is fully charged, the battery provides backup power for the CMOS setup and the real-time clock for
approximately 21 days. Before you remove a module from its power source, ensure that the battery within the module
is fully charged (the BATT LED on the front of the module goes OFF when the battery is fully charged). If the battery
is allowed to become fully discharged, the module will revert to the default BIOS and clock settings.

Note: The battery is not user-replaceable or serviceable.

1.4 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. The module is shipped with the Setup jumper OFF. Do not jumper the Setup
pins together unless you are directed to do so by ProSoft Technical Support (or to update
the module firmware).

The following illustration shows the MVI56E-DNPNET jumper configuration with the Setup
Jumper OFF.

February 13, 2015

Contents MVI56E-DNPNET ♦ ControlLogix Platform
User Manual DNPNET Ethernet Client/Server Communication Module

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.

1.5 Installing the Module in the Rack

Make sure your ControlLogix processor and power supply are installed and configured,
before installing the MVI56E-DNPNET 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 the MVI56E-DNPNET into the
ControlLogix chassis. Use the same technique recommended by Rockwell Automation to
remove and install ControlLogix modules.

You can install or remove ControlLogix system components while chassis power is applied
and the system is operating. However, please note the following warning.

Warning: When you insert or remove the module while backplane power is on, an electrical arc can occur. An

electrical arc can cause personal injury or property damage by sending an erroneous signal to the system’s

actuators. This can cause unintended machine motion or loss of process control. Electrical arcs may also cause
an explosion when they happen in a hazardous environment. Verify that power is removed or the area is non­hazardous 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 Align the module with the top and bottom guides, and then slide it into the rack until the

module is firmly against the backplane connector.

2 With a firm, steady push, snap the module into place.
3 Check that the holding clips on the top and bottom of the module are securely in the

locking holes of the rack.

4 Make a note of the slot location. You must 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 ControlLogix rack.

5 Turn power ON.

Note: If you insert the module improperly, the system may stop working or may behave unpredictably.

1.7 Connecting Your PC to the ControlLogix Processor

There are several ways to establish communication between your PC and the ControlLogix
processor. The following steps show how to establish communication through the serial
interface. It is not mandatory that you use the processor's serial interface. You may access
the processor through whatever network interface is available on your system. Refer to your
Rockwell Automation documentation for information on other connection methods.

1 Connect the right-angle connector end of the cable to your controller at the

communications port.

2 Connect the straight connector end of the cable to the serial port on your computer.

1.8 Downloading the Sample Program to the Processor

Note: The key switch on the front of the ControlLogix processor must be in the REM or PROG position.

1 If you are not already online with the processor, open the Communications menu, and

then choose DOWNLOAD. RSLogix 5000 will establish communication with the processor.

You do not have to download through the processor's serial port, as shown here. You
may download through any available network connection.

2 When communication is established, RSLogix 5000 will open a confirmation dialog box.

Click the DOWNLOAD button to transfer the sample program to the processor.

3 RSLogix 5000 will compile the program and transfer it to the processor. This process

may take a few minutes.

4 When the download is complete, RSLogix 5000 will open another confirmation dialog

box. If the key switch is in the REM position, click OK to switch the processor from
PROGRAM mode to RUN mode.

Note: If you receive an error message during these steps, refer to your RSLogix documentation to interpret and
correct the error.

1.8.1 Configuring the RSLinx Driver for the PC COM Port

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.

2 MVI56E-DNPNET Configuration

The DNP3 Ethernet configuration resides in the DNPNET controller tags. This section
covers the tag structure and descriptions of the DNPNET Client and Server parameters.

2.1 Assigning a Permanent IP Address

The module’s IP address, subnet mask, and gateway parameters are configured in the

DNPNET.CONFIG.IP_Settings controller tags only.

Any changes to the DNPNET.CONFIG.IP_Settings.IP, Netmask, or Gateway tags require
the trigger of the DNPNET.CONFIG.IP_Settings.Write tag. This sends the parameters to the
module.

The user can also read the current IP settings from the module by triggering the
DNPNET.CONFIG.IP_Settings.Read tag. They will populate in the
DNPNET.CONFIG.IP_Settings.IP, Netmask, and Gateway tags.

2.2 DNPNET Module User-Defined Data Types

The sample ladder logic relies heavily on the use of User-Defined Data Types (UDTs) to
help group and structure the wide variety and volume of data and control features the
module offers. Lower-order UDT structures are often embedded in higher-order structures to
help further organize data into more easily understood data collections.

User Manual DNPNET Ethernet Client/Server Communication Module

All data and control parameters related to the MVI56E-DNPNET are contained in User-

defined Data Types (UDTs). The DNPNETMODULEDEF UDT is the primary, top level data

structure in which all other lower-order data types are grouped and organized. All groups
branch down from this UDT.

To utilize all the features and functions of the module, an instance of each data type is
required. This is accomplished by declaring controller tag variables using these data types in
the Controller Tags Edit Tags dialog box.

Some UDTs hold process or status data (Module Data Objects). This data can be monitored

and manipulated by the application-specific ladder logic program. Other UDTs are used to
store and organize the parameters needed for special functions and control features

(Special Data Objects). These data types will be discussed in more detail in succeeding

topics.
