Server Explorer can use two types of server software to communicate with industrial automation devices: OLE for Process Control (OPC), and National Instruments Industrial Automation Servers (IAS or IAK). So by default, the Controller Link protocol will not show up in Server Explorer. Depending on the model, you might add support for your Omron product by simply purchasing the NI Industrial Automation OPC Server CD.
This product adds support for the following Omron devices to Server Explorer:
Omron HostLink via Serial
Omron C20, C200, C500, C1000, C2000 via serial
Omron CQM via Serial
Omron CPM1 via SerialOmron HostLink via Serial
Omron C20, C200, C500, C1000, C2000 via serial
Omron CQM via Serial
Omron CPM1 via Serial
Also, although I am not too familiar with Controller Link, I believe it's a proprietary communications protocol from Omron, in other words I'm not sure how easy it is to talk the Controller Link protocol without Omron's software. Here is the datasheet from their website:
If your model isn't listed above and included in the Automation OPC CD, the only way I can think to talk to your PLC's with the Controller Link protocol in LabVIEW, would be if the software that Omron provides C libraries that you could call with LabVIEW. Just by the looks of things, it appears that they want you to use their proprietary software Controller Link Support Software Version 2.0 or CX Programmer.
