Protocol Converter / Gateway from serial interface to PROFIBUS DP

The PROTOCOL CONVERTER UNIGATE CL connects devices such as automation components via their serial interfaces to the required fieldbus or industrial Ethernet standard. RS232, RS485 und RS422 interfaces are on Board as a standard feature.
The communication between the serial side and the bus takes place either through the device configuration and a selection of the commercially available protocol, such as Modbus ASCII, Modbus RTU (Master or slave), 3964 (R), RK512, DIN measuring bus, DIN 19244, or the device is controlled by a script.
This Script is created with the free PC tool, ‘PROTOCOL DEVELOPER’. You decide whether you want to program the Script yourself or hire Deutschmann Automation to do so.
A special feature of the UNIGATE CL series is Brand labeling. With the customized design Deutschmann Automation not only gives you the opportunity to pre-configure the device and choose different housing colors, you can also apply your own logo.

Your advantage

With the UNIGATE CL modules from Deutschmann you bring existing components into modern networks. As a device manufacturer you save the self-development of the respective fieldbus or Ethernet based interfaces. The consistency of the Deutschmann UNIGATE CL series allows once generated configurations and scripts to be used for other fieldbus and Ethernet based versions.

Advantage Deutschmann - This speaks for UNIGATE CL

  • Available for the most fieldbus and Industrial Ethernet versions
  • RS232, RS485- and RS422 interfaces are on Board
  • Same design on the serial side in all bus versions
  • The fieldbus or Ethernet side meets the standards, respectively the standard market models.
  • SSI protocol is supported e.g. for encoder
  • Built-in isolation on the bus side, optionally on the serial side
  • Configuration of the module via configuration tool WINGATE
  • Free programming with PROTOCOL DEVELOPER (Deutschmann Script language)
  • No adjustment of the device firmware needed
  • Additional debug interface on board
  • Modern, slim, DIN rail
  • Same Dimensions in all bus variants
  • Brand labeling, pre-configured according to the customer
  • Wide voltage range from 10 to 33 VDC
  • When using the RS485 interface, multiple terminal devices can be used on a PROTOCOL CONVERTER (e.g. Modbus RTU).
