Linking PROFINET and CAN

The module CAN-PN can link any PROFINET-IO controller to a CAN network. The CAN-PN gateway itself operates as a PROFINET-IO device with a maximum of 256 bytes input data and 256 bytes output data on the PROFINET bus.


The CAN-PN connects CAN modules with CANopen (CiA® DS 301) or layer-2 (ISO 11898-1) applications to e.g. a SIMATIC-S7. The number of logical CAN nodes is not limited by the gateway.

Physical Interfaces

The CAN high speed (ISO 11898-2) compatible interface allows a maximum data-transfer rate of 1 Mbit/s. The 100 BASE-TX PROFINET interface is compatible to IEEE802.3 and runs with 100 Mbit/s. The PROFINET as well as the CAN interface are electrically isolated.

Configuration and CAN Protocols

The module can be configured via PROFINET configuration tool, e.g. the PLC SIMATIC Manager or the TIA portal. No additional configuration tools are required!
