The OPC Data Access Client software functions only on Windows operating systems, starting with Window 2000 Service Pack 3 and beyond. This means the station must run on a Win-32 based platform, such as a JACE-NXS or -NX, AX SoftJACE, or a PC especially licensed for the OPC driver.

The OPC driver is not supported in any QNX-based platform, such as any JACE-2/6, -4, or -5 series controller.
