Linking DP and CAN

The module CAN-DP can link any Profibus-DP master to a CAN network. The DP/CAN gateway operates as a slave-I/O component with a total of maximum 300 bytes data (up to 244 bytes input and 56 bytes output or up to 244 bytes output and 56 bytes input data) on the DP-bus.


With the CAN gateway you can couple CAN modules with CANopen or layer-2 implementation to e.g. a SIMATIC-S7.
The number of CAN participants is not limited by the module.

Physical Interfaces

The ISO 11898-compatible CAN interface allows a maximum data-transfer rate of 1 Mbit/s. The Profibus-DP-Slave interface automatically recognizes all usual bit rates
up to 12 Mbit/s. The DP as well as the CAN interface are electrically isolated.

Configuration and CAN protocols

The gateway is configured via a PROFIBUS configuration tool, such as the SIMATIC Manager. CANopen is supported as layer-7 protocol on the CAN layer.
