EtherNet/IP to Modbus Master/Slave Communication Module
5201/5202-DFNT-MCM(4)
Product Description
The ProLinx family EtherNet/IP to Modbus Master/Slave communications module (5202-DFNT-MCM4) creates a powerful connection between devices on an EtherNet/IP network and Modbus devices. The module is a stand-alone DIN rail-mounted protocol gateway that provides one ethernet port and up to four serial ports.
The Ethernet/IP (DFNT) protocol driver supports the Explicit Messaging implementation of the protocol. User-configurable as both a Client and a Server, the EtherNet/IP port is a very powerful data transfer tool.
The Modbus (MCM) protocol driver supports Master and Slave implementations of the protocol. All Modbus serial ports are individually configurable, providing a very powerful and flexible host or device interface solution.
Product Applications
Functional Specifications
Internal Database
The ProLinx module contains an internal database that consists of areas for application data, status information, and configuration information.
The internal database is shared between all ports on the module and is used as a conduit to pass information from a device on one network to one or more devices on another network.
Application Data Area
The data area is used to store and retrieve data by the protocol drivers and for data exchange between protocols. The database is used as a source for write commands to remote devices and holds data collected from the remote devices. Commands defined in the configuration file (stored in the configuration data area) control how the data is to be handled in the database.
Status Data Area
This area is used to store error codes, counters, and port status information for each port.
Configuration File
This file contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, the module.
EtherNet/IP Protocol Specifications
The EtherNet/IP protocol is one of the primary connectivity tools to the different Rockwell Automation platforms. The Explicit Messaging aspect of the protocol (only) has been implemented in the ProLinx units to provide the data transfer link between the ProLinx units and the Rockwell Automation hardware. (Implicit Messaging (I/O communications) is not supported)

Modbus Protocol Specifications
The Modbus driver provides access to an internal database of 4000 registers (words), with extensive support provided for both the Master and the Slave implementations of the protocol. The serial port(s) on the gateway can be individually configured to support the Modbus protocol (Master or Slave, RTU or ASCII, Baud Rate, etc).
