Funktionen und Vorteile

The PROFIBUS DP Slave protocol driver supports the PROFIBUS V0 Slave implementation, providing powerful data transfer capability between the module and a ControlLogix processor. User configurable data mapping and DP port operation make the interface an easy to use and powerful data transfer tool.

The MVI56 module Configuration/Debug Serial port connects a PC to the module for configuration, status, monitoring, and troubleshooting (serial cable is included with product shipment). After editing on a PC, a configuration file is downloaded and stored on the MVI56 module.

The PROFIBUS DP Slave gives access to the unit's input and output images with up to 122 words of Input and Output data. Total input and output may not exceed 200 words. These Input and Output data blocks are mapped by the user within the module's data memory allowing maximum flexibility and data transfer with other protocols.


With the growing usage of the PROFIBUS DP protocol in the industrial marketplace, this product has a wide variety of application uses. Industries that use this technology include:

  • Power and distribution applications
  • Petrochemical
  • Water and Gas Applications
  • SCADA and DCS applications
