Fast and reliable linking PROFIBUS-DP and CAN
Application examples: SIEMENS SIMATIC-S7 to CAN layer 2 or CANopen®
DP-slave with a total maximum of 300 bytes data (partitioning from 244 bytes input and 56 bytes output to 244 bytes output and 56 bytes input)
CAN master: CAN layer 2, no limitation on CANopen PDO's and SDO's
No limitation on the number of CAN participants by the module
11- and 29-bit CAN-ID support
There is an alternative product. Please have a look at: CAN-DP/2

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.
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 module can be configured via PROFIBUS configuration tool, e.g. the PLC SIMATIC Manager.
CANopen is supported as layer-7 protocol on the CAN layer.
