Linking PROFIBUS-DP and CANopen
The module CANopen-DP can link any PROFIBUS-DP master to a CANopen network. The gateway operates as a PROFIBUS-DP slave-I/O component with a total of maximum 240 bytes input and 240 bytes output data. It supports cyclic (DP-V0) as well as acyclic (DP-V1) PROFIBUS data transfers. On CANopen it operates as a CANopen manager supporting CANopen master, NMT master and configuration functions. PDO and SDO (with SDO timeout and MPDO transmission) data transfers are supported. START frame, SYNC and Heartbeat are controlled by the module.
With the CANopen-DP gateway you can couple CANopen modules to e.g. a SIMATIC-S7. The number of CANopen devices 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 PROFIBUS-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 CAN-layer-7 protocol on the CAN layer. Additionally CAN-layer-2 functions are available.
