PN/CAN Gateway, PROFINET/CANopen Slave | Version 2 | 1/26/2021 10
2 System overview
2.1 General/area of application
The "PN/CAN Gateway, PROFINET/CANopen Slave" enables the coupling of machines with CANopen
bus to machines with PROFINET network. The PN/CAN Gateway represents a freely configurable,
fully-fledged CANopen device on the CAN bus and extended the PLC – system / machine to a
CANopen device.
On the PROFINET network, the PN/CAN Gateway is a PROFINET I/O device. The data of the CANopen
SDOs are transparently and freely configurable inserted into the PROFINET network and can thus be
read or written directly in the PLC.
The PN/CAN Gateway is integrated into the hardware configurator of the PROFINET controller with a
GSDML file, and all values of the PN/CAN-Gateways are available as IO information. Special handling
blocks are not necessary. An EDS or DCF file is used to permanently load a manufacturer-specific
CANopen device configuration into the device.
