I have an ordinary computer which communicates with several DSPs (CANBus communiation) through Compact Rio. The physical connection is that the DSPs' CANBuses are connected together and connected into Compact Rio, then the Compact Rio is connected with a router through Ethernet, at the same time, the computer also connects with the Router through Ethernet. Based on this physical architecture, the computer can run CANBus software model on Labview to communiate with Compact Rio and DSPs.
As I know, the communication between the computer and the Compact Rio is not real time, and the communication between Compact Rio and DSPs can be real time, can you tell me if I get the right point?
Now we have another device named RTDS (communicate with outside through Enternet based on DNP3), and want to add RTDS into our system. I am not sure about the way to conduct the communiation. The main question is that we need to run Labview to communicate with DSPs through CANBus and RTDS through DNP3 at the same time, is that possible?
I proposed two possible ways to conduct communication, bt not sure if it is possible.
1. I proposed that I connect RTDS with the Router through Ethernet, and then the computer communicates with RTDS through the Router based on DNP3 and also keeps the communication with DSPs through Router, Compact Rio, CANBus and then DSPs. I am wondering if this kind of communication is available for Labview.
2. The second possible way I proposed is that I connect the RTDS with Compat Rio (CRio keeps connecting with DSPs through CANBus) through Ethernet, and then the computer communicates with DSPs through Router, Compact Rio and CANBus, and the computer communicates with RTDS through Router, Compact Rio and Ethernet. Also, the computer needs to run Labview with CANBus sofeware model and DNP3 software model at the same time. I am also not sure if it is possible.
The diagram of the communication system is shown in the attachments.
