Battery Life Advisory
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.

1.1 What's New?
MVI56E products are backward compatible with existing MVI56 products,
ladder logic, and module configuration files already in use. Easily swap and
upgrade products while benefiting from an array of new features designed to
improve interoperability and enhance ease-of-use.
Note: To take advantage of the new expanded database and server capabilities, your MVI56EMNETC module needs to have firmware version 3.01 or higher, and your MVI56E-MNETC Add-On
Instruction needs to be version 1.8 or higher. Earlier versions have no server capabilities and
support up to 5000 user database registers.
More data memory: There are now 10,000 16-bit registers available for
user-defined module data memory (an increase from 5000).
Server capability: The module now supports up to 20 server connections
(10 MNET, 10 MBAP).
ProSoft Configuration Builder (PCB): New Windows software for
diagnostics, connecting via the module's Ethernet port or CIPconnect®, to
upload/download module configuration information and access
troubleshooting features and functions.
ProSoft Discovery Service (PDS): Utility software to find and display a list
of MVI56E modules on the network and to temporarily change an IP address
to connect with a module's web page.
CIPconnect-enabled: Allows PC-to-module configuration and diagnostics
from the Ethernet network through a ControlLogix 1756-ENBT EtherNet/IP™
module.
Personality Module: An industrial compact flash memory card storing the
module’s complete configuration and Ethernet settings, allowing quick and
easy replacement.
LED Scrolling Diagnostic Display: 4-character, alphanumeric display,
providing standard English messages for status and alarm data, and for
processor and network communication status.

The following components are included with your MVI56E-MNETC module, and
are all required for installation and configuration.
Important: Before beginning the installation, please verify that all of the following
items are present.
If any of these components are missing, please contact ProSoft Technology
Support for replacement parts.

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. Do not jumper the Setup pins together unless
you are directed to do so by ProSoft Technical Support.
The following illustration shows the MVI56E-MNETC 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.

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 MVI56E-MNETC 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 MVI56EMNETC 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 your 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 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 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.

4 Click OK to continue.
5 Edit the Module Properties. Select the Requested Packet Interval value for
scanning the I/O on the module. This value represents the minimum
frequency at which the module will handle scheduled events. This value
should not be set to less than 1 millisecond. The default value is 5
milliseconds. Values between 1 and 10 milliseconds should work with most
applications.
6 Save the module.

5 If you are using the module in a different slot (or remote rack), edit the
connection input and output variables that define the path to the module in
the FINAL NAME column (NAME column for controller revision 16 or less). For
example, if your module is located in slot 3, change Local:1:I in the above
picture to Local:3:I. Do the same for Local:1:O. If your module is located in
Slot 1 of the local rack, this step is not required.
6 Click OK to confirm the import. RSLogix will indicate that the import is in
progress:
When the import is completed, the new rung with the Add-On Instruction will
be visible as shown in the following illustration.
The procedure has also imported new user-defined data types, data objects
and the Add-On Instruction for your project.

field to change the values. You can also click the drop-down arrow to select
the correct name.
11 Change the default tags MNETC and AOI56MNETC to avoid conflict with
