Connection of PROFINET® IO and CANopen®

The CANopen-PN/2 connects any PROFINET® IO controller to a CANopen® network.
The fieldbus gateway operates as a PROFINET® IO device with a maximum of 1440 bytes of input data and 1440 bytes of output data and as a CANopen® manager with support for Network Management (NMT), Node Guarding and Heartbeat.


The CANopen-PN/2 connects CANopen® modules with CANopen® modules (CiA 301) with e.g. a SIMATIC-S7. A maximum of 126 CANopen® nodes can be connected to the gateway.

Physical Interfaces

The ISO 11898-2 compatible CAN interface allows a maximum data transmission rate of 10 kBit/s up to 1 MBit/s. The 100BASE-TX PROFINET® IO interface is compatible with IEEE802.3 and offers a data transmission rate of 100 MBit/s. Both the PROFINET® IO and CANopen® interfaces are galvanically isolated from the rest of the circuit.

Easy configuration and extensive debugging options

The module can be configured as a PROFINET® IO configuration tool via the GSDML Composer.
A live view of the CAN bus on a Windows PC is possible via the integrated USB interface with the free CANreal tool. This allows configuration errors to be found easily and quickly. In addition, it is possible to display the CAN statistics data on the utilization of the CAN bus in CANreal or directly in the PLC.
