Examples of using OPC servers (KepDirect specifically) or general LV/OPC tutorials?

[davey31415]

Hi,

I do a bit of work with both LabVIEW and Lookout Direct.  I'd like to phase out Lookout Direct and it seems that learning how to use LV with an OPC server is the first step.

Does anyone have example programs?  A tutorial on the subject would be helpful as well.

Please let me know if you have any general comments about working with OPC servers.

I'm looking specifically at KepDirect's server (Automation Direct's Direct Logic PLCs only).  My budget is tight and I am using DL PLCs exclusively.

Thanks,

Dave

Dave,

You should start with this example http://zone.ni.com/devzone/cda/tut/p/id/3978.

LabVIEW also has a module called DSC, which allows you to access the OPC server tags as shared variables. This is a more expensive option (the run time license is not free) but is recommended for over 10-20 tags.
