CAN-CBM-DP

PROFIBUS-DP®/CAN Gateway

Features

  • Fast and reliable linking PROFIBUS-DP and CAN

  • Application examples: SIMATIC-S7 to CAN layer 2 or CANopen®

  • DP-slave with up to 300 bytes data (partitioning from up to 240 bytes input and 60 bytes output to 240 bytes output and 60 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

There is an alternative product. Please have a look at: CAN-DP/2

Linking DP and CAN
The module CAN-CBM-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 (partitioning from up to 240 bytes input and 60 bytes output to 240 bytes output and 60 bytes input 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 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 by optocouplers and DC/DC converters.

Serial Interface
The module has a serial interface (default: RS-232) for service and configuration. It is connected by a DSUB9 connector.

Configuration and CAN protocols
For the I/O data mapping of the DP slave a configuration software for Windows95/98 or Windows NT is available. CANopen is supported as Layer-7 protocol on the CAN layer.
