Product Information

Product Description

The UNIGATE CL Gateway will EtherCAT-enable any RS232/485/422 serial or Modbus device by making it an EtherCAT Slave. 

One side of the gateway is a fieldbus, EtherCAT 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 low-cost and flexibility of UNIGATE CL devices are ideal for high volume applications.  Volume and OEM pricing available.

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 EtherCAT 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 EtherCAT Slave
  • Max. 1300 byte input and 1300 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
