Solution
Built-in Serial ports of cRIO or sbRIO cannot be directly accessed through FPGA. These ports are accessible only from Real-Time section, where they show up as a standard VISA resource. It is recommended to use Serial VIs and functions to communicate with devices connected to those ports. Additional functions are also available in the VISA palette .
If your application requires serial communication to be implemented on FPGA, there are several ways to do it, however additional hardware may be necessary:
Please note, that it may not be possible to connect C-Series modules to all sbRIOs. In case your sbRIO does not have C-Series module connectors, but it is equipped with RMC Connector, you may still connect C-Series modules via
C-Series RIO Mezzanie Card.
