Sensor device for LV subroutine using CAN?

Question

The product of our project will be a LabView subroutine that would take in a list of messages and output the responses to those messages. A named cluster might be an appropriate format for the output. The subroutine should be generic in that once it is fed the appropriate message(s), it can query across the CAN to the appropriate sensor. We need this capability because many new sensors that we use for testing come only with CAN outputs rather than the traditional voltage outputs. These are relatively simple transducers that don't have extensive vocabularies. Six messages may be sufficient for each of these applications.
CAN subroutine suggestions:
-six message (word?) capability These messages can be fed in as inputs specific to the particular transducer the routine to be used.
-named cluster output
-should be able to run in a 20 hz main loop if possible
**In order to proceed with this project, we need communication between the sensor and the bus, which is our main problem. When using MAX, we only get error transmission with a 100% bus load, does this means the sensor is actually working? Also, does anyone knows how to insert the sensor as a LV subroutine, once is communicating?
Thank you!

Answer 1

Ok, lets assume the device channel parameters are alright.
By named cluster I mean, just that, a cluster with a name that if save as a subVI, when use in a VI it displays as a cluster within the main VI. But thats not a big issue.
Today I finally created the subVI and is reading form the CAN device, now...how do I get it to writethe data is gathering into a file, preferably Excel? I am attaching what I have sor far, which works given a CAN device.
"Could you also describe more what you mean by six message/word capability?"
-The subroutine should be generic in that once it is fed the appropriate message(s), it can query across the CAN to the appropriate sensor. We need this capability because many new sensors that we use for testing come only with CAN outputs rather than the traditional voltage outputs. Some examples are the urea quality sensor that I've shown you, NH3 sensor, and NOx/O2 sensors all are CAN based. These are relatively simple transducers that don't have extensive vocabularies. Six messages may be sufficient for each of these applications, but this should be confirmed.
Thank you.
