Modbus TCP/IP Client/Server Enhanced Network Interface Module for ControlLogix

MVI56E-MNET/MNETXT

The MVI56E Modbus TCP/IP Client/Server Enhanced Communication Module allows Rockwell Automation ControlLogix processors to interface easily with Modicon Programmable Automation Controllers (PACs) and a wide variety of Modbus TCP/IP-compatible instruments and devices.

MVI56E enhancements include local and remote configuration and diagnostics through the module's Ethernet port, CIPconnect technology for bridging though Rockwell Automation ControlNet and EtherNetIP networks, and an on-board web server for access to module documentation and sample program files.

The MVI56E-MNET and MVI56E-MNETXT are functionally the same. The MVI56E-MNET is designed for standard process applications. The MVI56E-MNETXT is designed for the Logix-XT control platform, allowing it to operate in extreme environments, at higher operating temperatures, and has a conformal coating to protect it from harsh or caustic conditions.

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 five independent server connections for Service Port 502 (MBAP)
  • Supports five 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 severs
  • 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 from 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
