제품특징

The MVI56E Modbus TCP/IP Multi Client Enhanced Communication Module for Remote Chassis allows Rockwell Automation ControlLogix Programmable Automation Controllers (PACs) to interface easily with multiple Modbus TCP/IP server-compatible instruments and devices. The Multi Client module improves performance when controlling multiple servers on a Modbus TCP/IP network, by supporting up to 30 clients.
MVI56E enhancements include configuration and management through the module Ethernet port, CIPconnect technology for bridging through ControlNet and EtherNet/IP networks, and has a web server to access on-board documentation, Add-On Instructions, and sample program files.
This module uses a small I/O data image for transfer of data between the module and the ControlLogix processor, making it ideal for ControlNet or Ethernet applications with the module in a remote rack.

  • Supports up to 30 Clients
    -Faster response for multi server applications
    -Reduces network traffic
    -Minimizes impact to other server communications when one
    server device goes off-line
  • RSLogix 5000 Integrated
    -The module communication is integrated with RSLogix 5000
    using a supplied Add-On Instruction (AOI) or ladder file
    -No additional PAC/PLC programming required
  • Enable/Disable commands easily from ladder logic.
    -Programatically enable various networked devices and their
    functions to support multiple applications or recipes,
    without having to reconfigure the module
  • Remotely configure and diagnose problems
    -Easy to use Windows-based configuration software connects
    through remote racks using EtherNet/IP and/or ControlNet
    via a 1756-EnxT and/or 1756-CNB interface module without
    requiring RSLinx OEM saving you money
    -Allows support of IT and Automation network segmentation
  • Web-enabled Ethernet port
    -The module has a built-in web server for easy access to
    documentation, module status, and to update firmware
  • MVI56 backward compatible
    -Assists in extending current MVI56 applications by using
    newer technology that supports existing MVI56 ladder logic
    and module configuration
