Profinet-IO and CANopen interface

Connecting 127 CANopen nodes

The CANopen-PN by ESD (Germany) can link a Profinet-IO controller to a CANopen network. A maximum number of 127 CANopen nodes can be connected to the gateway.

The gateway operates as a Profinet-IO device with a maximum of 1440 bytes input data and 1440 bytes output data and connects CANopen modules with CiA 301 applications to e.g. a Simatic-S7. The CAN-compatible (ISO 11898-2) interface allows a maximum data-transfer rate of 1 Mbit/s. The 100Base-TX Profinet-IO interface is compatible to IEEE802.3 and runs at 100 Mbit/s. Both interfaces are electrically isolated.

The module can be configured via the configuration tool GSDML-Composer. CAN tools (CANreal, CANplot, CANrepro, CANscript, COBview) can be used additionally for CAN diagnostics. The gateway is designed according to Profibus International Document TC2-09-0002 (CANopen-Integration_7012 d07_Jul09).
