| Comment: |
UGS is comprised of the Universal OPC
Server (UOS) and the GSC2700.pro device profile. The UGS mnemonic is
used to identify this unique combination. UOS will also support many other devices that
use serial or TCP/IP communications. 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 GSC2700.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 in 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. |

| Device Commands Supported |
| The device commands supported are shown in
Table 1. They are described in reference to the profile command group that contains them.
A "profile command group" is a group of related commands. Usually it consists of
an I/O Device READ/WRITE command pair. However the command group can contain only a device
READ command, only a device WRITE command, or more than one device READ/WRITE pair. This
depends on the protocol of the I/O Device to which the command is directed. |
