Anybus X-gateway - CANopen Master - CANopen Slave

The Anybus X-gateway CANopen provide a seamless connection between a CANopen upper network and a secondary CANopen sub-network. This makes it possible to extend CANopen network and devices without a secondary PLC system.

The X-gateways primary function is with the fast transfer of cyclic I/O data between the two networks. I/O data from one CANopen network is written into CANopen objects that can be mapped into CANopen PDOs and vice versa. The gateway acts as a full CANopen Master/Manager on one side and a CANopen Slave on the other side. The data transmission between the two CANopen networks is completely transparent with a maximum data capacity of 510 bytes in each direction.

CANopen configuration can easily be made through the included Anybus Configuration Manager CANopen software, or with any other standard CANopen configuration tool. No programming skills are needed.
