Modbus TCP/IP Client/Server Enhanced Communication Module
MVI56E-MNET & MVI56E-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, and CIPconnect technology for bridging through Rockwell Automation ControlNet and EtherNetIP networks.
The Modbus TCP/IP Client/Server Enhanced Communication Module and Modbus TCP/IP Client/Server Enhanced Communication Module for Logix-XT are functionally the same. The Modbus TCP/IP Client/Server Enhanced Communication Module is designed for standard process applications. The Modbus TCP/IP Client/Server Enhanced Communication Module for Logix-XT is designed for the Logix-XT control platform, allowing it to operate in extreme environments. It tolerates higher operating temperatures, and has a conformal coating to protect it from harsh or caustic conditions.

Benefits
|
|
Backward-Compatible
|
- Upgrade earlier Modbus TCP/IP Client/Server modules without changing existing ladder logic programs or module configurations
- Enhanced features and flexibility without incurring expensive reprogramming costs
|
|
For Extreme Environments
(MVI56E-MNETXT only)
|
- Conforms to the EN60079-0 and EN60079-15 standards for applications in caustic and extreme temperature environments
- Operates in temperature extremes from -25° to 70° C (-13° to 158° F)
- Conformal coating protects against caustic or corrosive environmental elements
|
|
RSLogix 5000 Integrated
|
- Module communication is integrated within RSLogix 5000 using a sample Add-On Instruction (AOI) or sample ladder logic file
|
|
Graphical User Interface Software

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
- Transmits 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 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
Functional Specifications
- The MVI56E-MNETand MVI56E-MNETXT are functionally identical. The MVI56E-MNET is for normal process and control environments. The MVI56E-MNETXT is conformal coated for extra protection in harsh or caustic environments and operates in extreme high or low temperature environments.
- Both modules transfer data in the largest possible I/O image block sizes, which optimizes data through-put and update time.
- Both modules appear to the ControlLogix processor as input/output (I/O) modules, rather than communication modules.
- Both modules work well in local rack applications and may be used in remote rack applications. (For information on a remote rack optimized, reduced data block version of the inRAx MNET module, look for the MVI56E-MNETR.)
- Retrieving module status and executing special functions (command control, event commands, etc.) are supported in ladder logic by special block transfer code
