DP/CAN Coupler Layer 2

On the PROFIBUS-DP, the DP/CAN coupler is a normal participant.
The I/O data of the CANopen? participants is shown in the PROFIBUS in a transparent and freely configurable manner.
The DP/CAN coupler is integrated in the hardware configurator with a GSD file and can be completely configured there. Additional tools are not necessary.

The DP/CAN coupler Layer 2 allows you to connect any number of CAN participants to the PROFIBUS-DP.
The DP/CAN coupler Layer 2 must be parameterized in the hardware configurator as a PROFIBUS participant. Corresponding GSD files are included with the device.
The PROFIBUS side is configured as a DP slave; the interfaces correspond to EN 50170 and are electrically isolated.
The transfer rate from 9.6 kbps to 12 Mbps is automatically detected, and the size of the input and output information amounts to a maximum of 312 bytes.
The CAN bus interface complies with ISO/DIN 11898-2 and is electrically isolated.
The DP/CAN coupler can send and receive any CAN messages. Messages can be defined with a fixed identifier, the data of which is always visible as a peripheral image in PROFIBUS. Alternatively, the DP/CAN coupler Layer 2 has a transmit and receive buffer for any CAN messages.
The DP/CAN coupler Layer 2 also works in the extended ambient temperatures of -25 ?C to +70 ?C.
