Product description:

PROFINET/CAN Gateway CANopen Master

With the PN/CAN gateway CANopen Master, the connection of CANopen slaves to a PROFINET PLC is easy and straightforward.


On the PROFINET network, the PN/CAN gateway is a PROFINET I/O device, On the CAN network the PN/CAN Gateway is a CANopen master and support up to 126 Slaves with up to 1 Mbps.

The I/O data of the CAN participants is transparently displayed in a freely configurable manner on the PROFINET network and can thus be processed directly in the PLC. 

The PN/CAN gateway is integrated with a GSDML file in the hardware configurator and can be fully configured there. No other software tools for configuration or handling blocks for programming are necessary, making gateway use straightforward.

The features of the PN/CAN gateway are rounded out by MRP (media redundancy), as well as extensive diagnostic functions and an interface for online diagnostics.


The PN/CAN gateway CANopen represents a full-fledged CANopen master. As the master, it supports gateway network management, SYNC telegrams and node guarding/heartbeat for monitoring the participants and LSS services. Up to 16 PDOs can be configured for each CANopen slave. It is also possible to configure the CANopen participants using SDO frames and to administer emergency messages.



  • SDO communication
  • emergency messages
  • slave monitoring with heartbeat and node guarding
  • LSS services
  • Easy configuration using a GSDML file
  • no handling blocks or configuration software necessary
  • Supports CANopen master protocol 
  • Up to 126 CANopen slaves possible
