Accessing a AB ControlLogix Ethernet Bridge in LabVIEW

[Haggerty]

We have some AB SLC500 series PLCs that are currently reporting to our SCADA system (a P3 running NT 4 and an Access DB-- haha) via a DH+ network.  I'm researching the possibility of updating this system using LabVIEW.  We recently bought a ControlLogix system that acts as a gateway between the DH+ network and an Ethernet network, but now I need to figure out how to access and read the data in LabVIEW.  So far, I've figured out that I need to use the IA OPC Server software, then use the DSC module as a OPC client to connect to the tags.  Is this way off?  Any assistance/advice and/or links to tutorials, manuals that may be helpful would be greatly appreciated!

Thanks!

Haggerty,

That is correct. You can use IA OPC Servers (or any OPC server that supports your PLC for that matter) to make the data items available over OPC to LabVIEW, which is an OPC client. 

You can find some more information and a link to a nice DSC 8 tutorial/presentation here:

Hope this helps.
