OPC Client Sample Program

This section describes how to run the ALINK OPC Client sample program.

Before we continue, please make sure that PCIS-OPC software and the

NuDAQ PCI devices are installed correctly. Also, you should have run

NuDAQ PCI card OPC server (NQOPCSvr.exe) to configure the devices

and items existed on the server, and place the generated file NuDAQ.cfg

in the directory where NuDAQ PCI card OPC server locates.

Step 1. Click the Create Instance button to launch the NuDAQ PCI

card OPC server. A dialog box appears to let you choose

which OPC Server (NuDAQ.OPC.2, NuDAM.OPC.2 , or

HSL.OPC.2) you want to launch.
