EtherNet/IP Interface Module

MVI71-DFNT

The MVI71 EtherNet/IP (DF1 for Ethernet) Client/Server Communication Module is a PLC backplane compatible module that allows PLC processors to interface easily with EtherNet/IP protocol (Explicit Messaging) compatible devices and hosts. Devices commonly supporting the protocol include Rockwell Automation PLCs, and host HMI systems.

Features and Benefits

The MVI71-DFNT module is a single slot solution that provides a powerful connection between Rockwell Automation's PLC processor and EtherNet/IP (DF1 for Ethernet) network applications.

The module can send read or write commands to remote devices on the EtherNet/IP network. The MVI71-DFNT also has 20 servers that allows the module to receive commands from remote devices. The MVI71-DFNT Pass-Through server allows the user to edit and transfer the PLC ladder logic using an Ethernet connection. Up to 100 commands can be configured by the user.

General Specifications

• Single Slot - 1771 backplane compatible
• The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module
• Ladder Logic is used for data transfer between module and processor. Sample ladder file included.
• Configuration data obtained from configuration text file downloaded to module. Sample configuration file included.

  • A response timeout of 1 to 65535 mSec
  • A retry count of 0 to 20
• Status data available in ladder logic

Support for PLC processor programming over Ethernet using a TCP/IP service and a serial port on the module connected to channel 0 of the processor. The module's third port emulates Channel 0 of the processor to pass through messages from the port to the processor

Server Specifications

• Supports EtherNet/IP explicit, connected, and unconnected class messaging
• Twenty independent server connections permit remote clients to interact with all data contained in the module
• Data can be derived from other clients on the network, through the client on the module, or from the PLC processor

Client Specifications

• Actively issues connected, explicit messages to other nodes on the network
• Supports 100 user-defined commands from a single client
• Allows command control from ladder logic
• Pass-through services
• Permits remote programming of the PLC processor on the Ethernet network via a pass-through
• TCP/IP service and a serial communication port (pass-through port) on the module
• The third port on the module can emulate the Channel 0 port on the PLC, This allows a DF1 master device attached to the emulated (Channel 0) port to monitor and control data in the PLC.
