Labview vi to read a Omega CN9 temperature controller

[Tony Asn]

I am trying to get Labview to read the output on a temperature controller (only need the output, no control is needed) and am having difficulty with the PC to even pick up the controller on the port. 

Any help would be much appreciated.  Thanks!

Have you gone through the communications setup defined in this document?  The controller appears to use Modbus, which means you need to know the addresses associated with the current temperature, so you'll need this document.

LabVIEW does not support Modbus out of the box, but you can find some Modbus libraries here and searching the forums for Modbus will yield some other modbus examples and discussions.
