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.

 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.

 ProSoft Discovery Service (PDS) (included in PCB)
 Pentium® II 450 MHz minimum. Pentium III 733 MHz (or better)

recommended

 Supported operating systems:

o Microsoft Windows 10
o Microsoft Windows 7 Professional (32-or 64-bit)
o Microsoft Windows XP Professional with Service Pack 1 or 2
o Microsoft Windows Vista
o Microsoft Windows 2000 Professional with Service Pack 1, 2, or 3

1.3 Package Contents

The following components are included with your MVI56E-MNETCR 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-MNETCR 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.

User Manual Modbus TCP/IP Multi-Client Enhanced Communications Module for Remote Chassis

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-MNETCR 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 MVI56E­MNETCR 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.

MVI56E-MNETCR ♦ ControlLogix Platform Start Here
Modbus TCP/IP Multi-Client Enhanced Communications Module for Remote Chassis User Manual

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.
