With the PN/CAN gateway, the connection of CAN devices to PROFINET is easy and straightforward.


The PN/CAN gateway SAE J1939 can be used as a complete SAE J1939 device or for the simulation and diagnosis of an SAE J1939 network.
The data of the Parameter Groups (PGNs) can be exchanged directly in the I/O data area of the PLC.
The gateway is completely configured with the help of a GSDML via the PROFINET configuration and does not require any additional software.
The source address (SA) is freely adjustable. Single and multi-package messages are freely available in direct communication and as requests.
In addition, the device can be used as a passive participant for transparent reading of PGN messages of an SAE J1939 network.

The features MRP (media redundancy) as well as extensive diagnostic functions and an interface for online diagnostics complete the performance features of the PN/CAN gateway.
