Serial Comm Project

[petersrj]

I am new with LabView so I need some general/basic guidance.

I have a serial Modbus based project.  The project needs to repeatedly make 3 calls each getting 64 registers which then need to be processed (read only for right now).  I need to update ~every 3 seconds or so.  I am using the MB Serial Master Query.  I am getting timeout errors which I want to minimize/manage.  Here are my questions:

1.  I am using a timed loop with three sub-diagrams.  Is this the best way?

2.  Is there a way to know when one of the calls ends (to control time in between calls)?

Thank you for your help.

Hi petersrj,

Unfortunately, the Mosbus libraries are not an officially supported or a fully tested library. The DSC Module is the supported form of communication. It would be a good idea posting this in the Industrial communication forum:

They might have some more experience with this library and type of communication than the users in this forum.
