NI-CAN CAN Bus Simulator

[wjh_2000]

I am planning on using a NI 9861 CAN bus card in a Compact RIO card cage to connect to a network of 8 CAN bus sensors, as shown below.

Before the entire system is up and running I would like to use a second Compact RIO card cage with 8 NI 9861 CAN bus cards to simulate the 8 sensors.

I believe this will work, but is there a way to simulate the 8 sensors using a single NI 9861 card.  Is it possible to get a NI 9861 card to respond to more than 1 remote frame ID?  If it is not possible for the NI 9861 card to respond to more than 1 remote frame ID can the identifier field for the NI 9861 card be changed on the fly.  This will allow the NI 9861 to emulate each of the 8 sensors without stopping the system to change the ID address of the NI 9861 card that is emulating the sensors.

Thanks

Hi wjh_2000,

Yes, it will be possible to simulate multiple devices with just one NI 9861.  However, you may have to write the logic yourself to make the second cRIO respond correctly to the different remote frames.  Look through the example finder though for a good start!

Best,
