| Comment: |
UEM is comprised of the Universal OPC
Server (UOS) and the EM1_UOS.PRO device profile. The UEM mnemonic is
used to identify this unique combination. UOS will also support many other devices that
use serial 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 EM1_UOS.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. |

|
Profile
Command Group Name |
Description |
| R/WLoopParam |
Use this command group to read or write the value for a
single LOOP parameter. This command group uses the Eurotherm EM-1 protocol command to
"Query a Single Parameter" (L##Y). Where:
L Loop
## Loop Number
Y Single Code letter desiginating a loop parameter |
| R/WMonitorParam |
Use this command group to read or write the values of a
single MONITOR parameter. This command group uses the Eurotherm EM-1 protocol command
to "Query a Single Parameter" (M##Y).
Where:
M Specifies access to a Monitored variable
## Monitored Variable number
Y Single Code letter desiginating a monitored parameter |
| SystemStatus |
Use this command group to read the number of system alarms
that are present. This command group uses Eurotherm EM-1 protocol command (SS). |
| SysAlarmList |
Use this command group to read a list of up to 4 system
alarms. This command group uses Eurotherm EM-1 protocol command (SA). |
| RemoteAlarmAck |
Use this command group to acknowledge alarms without operator
interaction. This command will turn all new alarms into old alarms. This command group
uses Eurotherm EM-1 protocol command (SX). |
| TestMessage |
Use this command group to read the system test message. This
command group uses Eurotherm EM-1 protocol command (XS0). |
| SysErrorInterrogation |
Use this command group to interrogate the EM-1 system to
determine if the system comfiguration has been changed. This command group uses Eurotherm
EM-1 protocol command (S?). |
