I can read from a VISA already, how do I write back to it?

I have a VI that reads a translated CAN message in 485.  I can read from the board fine, as well as parse what i need out, but I want to write back to it.  I have attached my VI, what command / block do I need outside the "write" case structure to tell it where to write too?

Hi Chris,

 

I like the VI you created and am impressed with the ability to deconstruct the CAN protocol.  When performing a write it is not going to be a simple task to constuct and output the string equivalent to the individual bits that the CAN network and devices are expecting.  As I look further into the necesity of what you would need to do to perform this I am wondering why you are looking to communicate with a CAN network through RS485?  We do offer reasonable CAN products that come with our CAN driver to easily communicate with a can network if you are looking for an alternative.

 

Thanks
