CAN-DP
Profibus-DP / CAN Gateway
- Fast and reliable linking Profibus-DP and CAN with data buffering
-
CAN-PLC link, e.g. to SIEMENS S7-300 or S7-400
-
No limitation on the number of CAN participants
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 maximum total of 300 bytes data (up to 244 bytes input and up to 244
bytes output data) on the DP-bus.
Applications
With the CAN gateway, you can couple CAN modules with CANopen or layer-2 implementation to e.g. a SIMATIC-S7.
The module does not limit the number of CAN participants.
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 opto- isolated.
Configuration and CAN protocols
Configuration is possible via a PROFIBUS configuration tool,
e.g. the PLC SIMATIC Manager. CANopen is supported as layer-7 protocol on the CAN layer.

CAN - DP Profibus - DP / CAN Gateway
esd electronics, Inc’s module CAN - DP links 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 up to 244 bytes output data) on the DP-bus. The CAN - DP gateway allows you to couple CAN modules with CANopen or layer-2 implementation to e.g. a SIMATIC-S7, and the number of CAN participants is not limited by the module.
The fully ISO 11898 compatible CAN interface allows a maximum data-transfer rate of 1 Mbit/s, and the Profibus - DP - Slave interface automatically recognizes all usual bit rates up to 12 Mbit/s. Both the DP and the CAN interface are electrically isolated.
The module can be configured with a PROFIBUS configuration tool such as the PLC SIMATIC Manager and CANopen is supported as layer-7 protocol on the CAN layer.
