Modbus TCP/IP Client/Server Communication Module
MVI46-MNET
The MVI46 Modbus TCP/IP Communication Module is designed to allow SLC processors to interface easily with other Modbus TCP/IP protocol-compatible devices using client and server functionality.
Compatible devices include not only Modicon processors (which support the Modbus TCP/IP protocol) but also a wide assortment of other clients and server devices.
Features and Benefits
The MVI46-MNET module is a single slot solution that provides a powerful connection between Rockwell Automation's SLC processor and Modbus TCP/IP network applications.
The TCP/IP Modbus network applications include those networks hosted by Modicon Quantum processors, networks controlled by operator interface software packages, and the growing number of manufactured devices that support this protocol. The module acts as an input/output module between the Modbus TCP/IP network and the Rockwell Automation backplane. The data transfer from the processor is asynchronous from the actions on the Modbus TCP/IP network. A 5000-word register space in the module exchanges data between the processor and the Modbus TCP/IP network.
- Support for the storage and transfer of up to 5000 registers to/from the SLC processor using M0/M1 data file transfer
- User-definable module memory usage
- 10/100 MB Ethernet compatible interface
- Configurable parameters for the client and server applications and floating point support
General Specifications
- Single Slot - 1746 backplane compatible (Local or extended I/O rack only. Remote rack not supported)
- The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module using M0/M1 files
- Ladder Logic is used for data transfer between module and processor. Sample ladder file included
- Configuration data obtained from configuration text file downloaded to module. Sample configuration file included
Applications
With the growing trend of Ethernet technology in the industrial marketplace, this product has a wide variety of application uses.
- Food processing
- Petrochemical
- Pulp and paper
- Automobile manufacturing
- Water and Wastewater
- Oil and Gas
- Power and Electric
