Comment: UW5 is comprised of the Universal OPC Server (UOS) for Serial and TCP/IP Devices and the WAT945.PRO device profile. The UW5 mnemonic is used to identify this unique combination. UOS will also support many other serial or TCP/IP device profiles. Please refer to our web site for the current list.
UOS is a stand-alone OPC Server that can be used with any OPC compliant Client such as Intellution’s FIX® or FIX Dynamics® or OA’s Enterprise Automation software. UOS has many advanced features like: DataView, DataScope, Serial and TCP/IP communications support, and multiple "different" device support. Please refer to our web site for more information on UOS capabilities.

Introduction
This document provides general information on the device commands supported by UOS and the UW5.PRO profile. If you have installed UOS, you should also review the sections titled About the I/O Driver, How Do I…, Setting up The I/O Driver, and Using the PowerTool in the UOS electronic documentation. To get there, click on Help and Help Topics on the PowerTool menu bar. The PowerTool is a client application with a graphical user interface that accesses the UOS OPC Server and lets you view and modify communications channel, device, and datablock properties.
