Programatically changing data socket IP for OPC

[bdwhaley]

Hello,

I am using a string indiactor which is configured with the data socket (OPC lookout) settings. I am having a difficult time changing the IP address of the datasocket URL (ie- lookout:\\172.24.149.2X\LV\digame\Control_Parms) using property nodes. Has any one been able to do this??

Thanks,

Brad,

What version of LabVIEW RT are you running? There was an issue in LabVIEW 6.0.3 the DataSocket VI's could not have different URL's passed through them. E.G. If you had one DataSocket Read in a For Loop that auto-indexed through an array of 10 URL's, you would always get the data from the first URL.

Also, remember that a number of VI server functions are only available on development machines and not available when built as an executable. Check the online help on the property node to determine whether the property you are using is available at all times or only in development mode.

Regards,
Aaron
