Serial communication between cRIO-9014 and a measurement instrument

[PeterSa]

Hello,

I am working with a cRIO-9014 and want to connect a secondary measurement and control process instrument (it is a "0254" by Brooks Instrument) to the RS-232 port. The "0254" is used to control two mass flow controllers. Brooks provides LabVIEW example VIs and a driver DLL to control it directly from the PC via the serial port, but not with LabVIEW FPGA. Is it possible to pass the commands through the cRIO to the "0254" device? I am relatively new to LabVIEW and don´t really know where to start. I am very grateful for any help.

Thank you,

Peter

You do not need to use the FPGA.  The serial port is going straight to the RT.  But you will have to make your own driver built on VISA to send the commands and recieve the data.  The Windows DLL will not work on the RT system.  So you will need a programmer's manual or a list of commands from the manufacturer.
