Programming

Subject of this Section

This section describes the tools available to program the operation of and obtain information on a open bus managed by card TSX CPP 110.

It is possible to program the operation of the open bus using UNI-TE requests:

Send and receive SDO messages on the bus,
Access the link layer by sending PDUs.

It is also possible to monitor the bus and its operation:

Identification of the master,
Send diagnostics requests on bus devices.

These requests are sent to the CANopen master (TSX CPP 110 PCMCIA card) to be processed.
