Comment: USK is comprised of the Universal OPC Server (UOS) for Serial and TCP/IP Devices and the SEN_MOLD.PRO device profile. The USK 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 SEN_MOLD.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.
 
Device Commands Supported
The device READ/WRITE 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.

DBB I/O Addressing Examples
Table 3 shows examples of how the user should enter I/O addresses in the FIX Database Builder I/O Address field. Examples will be given for several of the variables listed in the Table 2 "Variables" column.
 
Table 3 - DBB I/O Addressing Examples
Command Group Name Variable DBB Block Used DBB I/O Address (Note 1) COMMENTS
SP SP AR D11:SP:SP:0 Read/Write Setpoint
V1  V1 AI D11:V1:V1:0 Read Process Variable 1, Water Temp. to the Process.
V2 V2 AI D11:V2:V2:0 Read Process Variable 2, Water Temp. from the Process.
V3 V3 AI D11:V3:V3:0 Read Supply Water Temperature
AL RC DR D11:AL:RC:0 Read Alarms, DR Block node:tagname.field Addressing was used to access all eight alarm bits. Ex. FIX:D11_RC.F_00, FIX:D11_RC.F_01, etc….
ON N/A DO D11:ON:WRITE Write Command to go into Startup Cycle (NOTE 3) Polling should be disabled.
OF N/A DO D11:OF:WRITE Write Command to go into Standby Cycle (NOTE 3) Polling should be disabled.
HLW N/A DO D11:HLW:WRITE Initiates high alarm setpoint to device. The poll record must be configured in the Poll Record Edit dialog box as Write-On-Demand. Refer to Note 3.
LLW  N/A DO D11:LLW:WRITE Initiates low alarm setpoint to device. The poll record must be configured in the Poll Record Edit dialog box as Write-On-Demand. Refer to Note 3.
HLW HL AO D11:HLW:HL:0 Holds High Alarm Setpoint Value. Setpoint is not written until Write-On-Demand occurs. Refer to Note 3.
LLW LL AO D11:LLW:LL:0 Holds Low Alarm Setpoint Value. Setpoint is not written until Write-On-Demand occurs. Refer to Note 3.
