Modbus TCP/IP Client/Server Enhanced Communication Module with Reduced Data Block

MVI56E-MNETR

The Modbus TCP/IP Client/Server Enhanced Communication Module with Reduced Data Block allows Rockwell Automation ControlLogix processors to interface easily with Modbus TCP/IP-compatible devices, such as Modicon Programmable Automation Controllers (PACs) and a wide variety of Modbus TCP/IP-compatible instruments and devices.

The MVI56E-MNETR uses a reduced Input/Output (I/O) data image block size for transferring data between itself and a ControlLogix processor. This makes it ideal for remote rack applications using ControlNet or EtherNet/IP process networks. The module also works well for applications that require redundant ControlLogix processors.

MVI56E-MNETR enhancements include local and remote configuration and diagnostics through the module's Ethernet port, and CIPconnect technology for bridging through Rockwell Automation ControlNet and EtherNetIP networks.

Configuration

ProSoft Configuration Builder (PCB) provides a PC-based software configuration solution for quick and easy management of module configuration files, as well as viewing communication and network diagnostics. The MVI56E-MNETR Setup Guide and sample configuration provide a quick and easy example with step-by-step instructions on how to move data through the module from the MNET network to the processor.

General Specifications

• Backward-compatible with previous MVI56-MNET versions
• Single-Slot 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
• CIPconnect-enabled network configuration and diagnostics monitoring using ControlLogix 1756-ENxT and 1756-CNB modules and EtherNet/IP pass-through communication
• Reduced I/O image size designed specifically to optimize remote rack implementations
• 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 (AOIs) 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, allowing quick in-the-field product replacement by transferring the CF card

Modbus TCP/IP Specifications

• ProSoft Technology's Modbus TCP/IP implementation (MNET) includes both Client (Master) and server (slave) capabilities
• 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 possible, including support for Enron or Daniel floating-point formats

Modbus TCP/IP Server (Slave)

• Supports ten independent server connections for Service Port 502 (MBAP)
• Supports ten independent server connections for Service Port 2000 (Encapsulated)
• Accepts Modbus Function Codes 1, 2, 3, 4, 5, 6, 8, 15, 16, 17, 22 and 23
• Module data can be derived from other Modbus server devices on the network through the Client or from the ControlLogix processor

Modbus TCP/IP Client (Master)

• Actively reads data from and writes data to Modbus TCP/IP devices, using MBAP or Encapsulated Modbus message formats
• Transmit Modbus Function Codes 1, 2, 3, 4, 5, 6, 7, 15, and 16
• Offers one Client connection with up to 100 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)

Status Data

• Error codes, counters, and module status available from module memory through the server, through the Client, or through the ladder logic and controller tags in RSLogix 5000

Functional Specifications

• The MVI56E-MNETR transfers data in smaller I/O blocks than the MVI56E-MNET, which makes it ideal for installations in remote racks or where bandwidth is limited.
• Works well with redundant ControlLogix Programmable Automation Controllers (PACs) using ControlNet.
• Module appears to the ControlLogix processor as an input/output (I/O) module
• 40-word scheduled I/O image blocks used for data transfers require significantly less bandwidth than the MVI56E-MNET
• Retrieving module status and executing special functions (command control, event commands, etc.) are supported in ladder logic by special block transfer codes
