Modbus TCP/IP Multi-Client Enhanced Communications Module

MVI56E-MNETC

The MVI56E Modbus TCP/IP Multi-Client Enhanced Communication Module 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, and CIPconnect technology for bridging through ControlNet and EtherNet/IP networks.

Configuration

ProSoft Configuration Builder (PCB) provides a graphical configuration tool for quick and easy management of module configuration files, as well as for viewing module diagnostic information. Route connections over multiple EtherNet/IP or ControlNet paths with CIPconnect technology, allowing you to manage the module from remote locations. The MVI56E-MNETC Setup Guide, with the sample configuration, provides step-by-step instructions on how to move data through the module from the Modbus TCP/IP network to the processor.

General Specifications

• Backward compatible with previous MVI56-MNETC versions
• Single-slot 1756 ControlLogix backplane compatible
• 10/100 Mbps auto crossover detection Ethernet configuration and application port
• User-definable module data memory mapping of up to 5000 16-bit registers
• ProSoft Configuration Builder (PCB) software supported, a Windows-based graphical user interface providing simple product and network configuration
• Sample ladder logic and Add-On Instructions (AOI) are used for data transfer between module and processor
• 4-character, alpha-numeric, scrolling LED display of status and diagnostics data in plain English - no cryptic error or alarm codes to decipher
• ProSoft Discovery Service (PDS) software used to locate the module on the network and assign temporary IP address
• Personality Module - a non-volatile industrial-grade Compact Flash (CF) card used to store network and module configuration for easy disaster recovery, allowing quick in-the-field product replacement by transferring the CF card

Modbus TCP/IP Client (Master)

The MVI56E-MNETC is a Client-only module that will operate on a local or remote rack. This module was created to improve performance when controlling multiple servers on a Modbus TCP/IP network. The module supports up to 30 Clients with up to 16 commands for each Client.

• Actively reads data from and writes data to Modbus TCP/IP devices, using MBAP or Encapsulated Modbus message formats
• Transmits Modbus Function Codes 1, 2, 3, 4, 5, 6, 7, 15, and 16
• Offers 30 Client connection with up to 16 commands to talk to multiple servers
• ControlLogix processor can be programmed to use special functions to control the activity on the Client by actively selecting commands to execute from the command list (Command Control) or issuing commands directly from the ladder logic (Event Commands)

Functional Specifications

• Modbus data types overlap in the module's memory database, so the same data can be conveniently read or written as bit-level or register-level data.
• Configurable floating-point data movement is supported, including support for Enron or Daniel floating-point formats.
• Special functions (command control, event commands, status, etc.) are supported by message transfer (unscheduled) using the MSG instruction.
• Configurable parameters for the Client, including a minimum response delay of 0 to 65535 ms and floating-point support
• Supports up to 30 Clients with up to 16 commands for each Client
• Error codes, counters, and module status available from module memory through the Clients, or through the ladder logic and controller tags in RSLogix 5000
