The CW-102 extends the CW-100 series with a gateway to connect CAN bus and Ethernet. Not only does it offer the user a simple and fast, but also a favourable economic solution to access CAN buses via IP networks. That makes it possible, for instance, to query distant measurement systems (remote maintenance) and also to position and check sensors and actuators with a CAN connection as required.

The CW-102 supports bidirectional data transfers: It packages CAN messages in a TCP/IP frames and transmits them via LAN - over Intranet and/or Internet. In the opposite transmission direction the TCP/IP frames are broken down into suitable CAN messages.

In doing so, the CAN-Ethernet gateway functions independent of the CAN protocol used: Established protocol standards such as CANopen and DeviceNet are processed as equally as are proprietary protocols. It is possible to directly access the CW-102 via Ethernet or it can be integrated in proprietary projects via the API included in the scope of service.

With the extension for SCPI it is possible to query measuring devices and make their measured values available via the CAN bus. On the other hand it is also possible to programme measuring devices via the CAN bus.


  • Bidirectional CAN-Ethernet Transmission/Conversion
  • CAN bridge functionality (CAN-over-Ethernet)
  • Connection of up to 5 CAN networks via Ethernet
  • Quick and easy to install 
  • Setting parameters via web interface
  • Easily extend and scale measurement systems operated on CAN bus
  • Integrate in proprietary programmes via API
  • Connect to measuring devices utilizing SCPI
