XNET CAN Interface already used?

[Madottati]

Hello,

I am running an XNET Signal single piont out session, it is a normal rest bus simulation with cyclic frames.

Now I have another code module, which uses a Frame Queued Out session on the same CAN interface.

At the initialization of the Frame Queued Out session, I want to know whether the interface is already initialized by another session. If not, I set the baud rate and the termination property for the Frame Queued Out session. Otherwise I let these settings as they are initialized by the other session.

If these properties are already set by another session, I get an error, because these can be only written when the interface is stopped.

How to do that?

Try using the XNET Read(CAN Comm State).vi. It will report what the current communication state is. If the interface has not been started it will return "Init". If the interface has been started it will return "Error Active" or "Error Passive".
