Product-specific answers based on available technical information.
No. It uses NI-Industrial Communications for CANopen. NI explicitly states that basic CAN communication using a DBC database file is not supported.
No. NI states that the PXI-8531 cannot be used in a slave configuration. Support for configuring slave nodes through LSS does not mean the interface itself can act as a slave.
Use NI's supported hardware and software reference, then verify the requirements for the intended driver release. The reference lists an NI Real-Time PXI controller configuration and includes a Phar Lap support-removal notice.
