Modbus Master/Slave to PROFIBUS Master Communication Gateway
5104-MCM-PDPMV1
Product Description
The ProLinx family Modbus Master/Slave to PROFIBUS Master communications gateway (5104-MCM-PDPMV1) creates a powerful connection between devices on a Modbus network and PROFIBUS DP Slave devices. The module is a stand-alone DIN-rail mounted protocol gateway that provides one serial port and one PROFIBUS Master DB9F port.
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.
The PROFIBUS DP Master protocol driver (PDPMV1) supports complete Master specifications according to IEC 61158 on either a Mono-Master or Multi-Master network. The module supports the DPV1 specification.
Product Applications
The MCM-PDPMV1 gateways are the ideal solution for the many applications where Modbus connectivity can be used to integrate a PROFIBUS DP Slave device into a system.
The Modbus Master/Slave gateway is a powerful gateway designed with Client and Server support, enabling easy connection to Rockwell Automation PLCs (CLX, SLC, PLC, CPLX, and similar devices). In combination with the PROFIBUS DP Slave device support, the gateway provides a very powerful interface to the many PROFIBUS devices which are in use in the industrial marketplace today. Applications for the gateway are found in most industries, especially the Manufacturing, Oil and Gas, Electrical Power and Food Processing

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 Data Area
This area contains module configuration information such as port configuration, network information, and command configuration. This configuration file is downloaded to, or uploaded from, this area.
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).
