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.

Configuration

ProSoft Configuration Builder (PCB) provides a PC-based software configuration solution for quick management of configuration files, as well as viewing communication and network diagnostics.
PCB is not only a powerful solution for new configuration files, but also allows you to import information from previously installed (known working) configurations into new projects.

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.

• Support of up to 4000 PLC registers user data files
• User-definable module memory usage
• 10/100 MB Ethernet compatible interface
• Functions as a server or a client
• Configurable parameters for the client include:
  • A minimum response delay of 0 to 65535 mSec
  • 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.
