Product Information

Product Description

Profibus-enable any RS232/485/422 serial or Modbus device with the UNIGATE CL Gateway. Make any serial device a Profibus DP Slave using the UNIGATE CL Profibus Gateway. Its low-cost and flexibility are ideal for high volume applications. One side of the gateway is a fieldbus, Profibus DP slave, while the other side is a high performance serial port that directly interfaces with your serial device. The serial side of the UNIGATE can either be used in one of many standard configurations (including Modbus RTU master/slave and standard RS232/422/485), or can be customized with its built-in scripting language.

The UNIGATE CL Gateway allows for the quick development of custom applications on the serial side using its powerful scripting language. When developing a custom application, or for simple configuration to a standard protocol, we recommend using a Starter Kit. Starter kits contain all the connection cables and power supplies for configuring and/or scripting. There is even a Profibus Master tool for testing your configuration or script. Scripts are written using the Protocol Developer Tool. If you need a custom protocol and scripting is not for you, Grid Connect offers scripting services at reasonable rates (call for details).


  • Complete Profibus Slave
  • Max. 244 byte input and 244 byte output data
  • Script language for optimal adaptation to your field device
  • Easy configuration from MS Windows® using the WinGate tool.
  • Develop customized scripts with the free Protocol Developer software tool
  • Scripts are portable between all other UNIGATE CL or IC Gateways
