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.

Table 1 - Device Commands Supported by the SEN_MOLD.PRO Profile

If the Profile Command Group is…	Then the Device READ command is…	And the Device WRITE command is…	Description
SP	SP	SP	Read/Write Setpoint
V1	V1	N/A	Read Process Variable 1, Water Temp. to the Process.
V2	V2	N/A	Read Process Variable 2, Water Temp. from the Process.
V3	V3	N/A	Read Supply Water Temperature

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.
