Issue
User has a device in Power Monitoring Expert that does not export OPC tags when "Update OPC" is selected in Management console. The device does not have a measurement template in DefaultMeasurements.xml in the ...\system\IONServices folder nor extension in ...\system\IONServices\DefaultMeasurementsExt

Product
Power Monitoring Expert 8.2
Power Monitoring Expert 9.0
Power Monitoring Expert 2020
Power Monitoring Expert 2021
Power Monitoring Expert 2022
Power Monitoring Expert 2023

Environment
Text Editor

Cause
When Update OPC is selected in the Management Console, the system will read the DefaultMeasurements.xml file and the contents in the folder DefaultMeasurementsExt. If the device type is not found in these files the ...\config\IONServices\IONServicesConfigurtion.xml file does not populate the desired device

Resolution

Previous versions of the software would require editing the defaultMeaurements.xml file to add the desired device. A more sustainable method is to create a new extension file.
In the instructions below, replace the text MyNewDevice with the name of the device type as seen in the Management Console

1. In the ...\system\IONServices\DefaultMeasurementsExt folder create a new text file and change the file name and extension to DefaultMeasurements_MyNewDevice.xml
2. Open the file in a text editor
3. Copy the following text into the file. Additional text will be required later

<?xml version="1.0" encoding="utf-8"?>
<!--The follow is catagorized by features that contain one or more Ctxts. A Ctxt refers to perspective (labeling) or system details (wiring cofiguration)-->
<DefaultMeasurements xmlns="http://rddl.xmlinside.net/PowerMeasurement/configuration/IONServices/MeasurementTemplates/1/" xmlns:f="http://rddl.xmlinside.net/PowerMeasurement/configuration/IONServices/defaultMeasurements/1/">
<MeasurementTemplates>
<MT name="MyNewDevice">


</MT>
</MeasurementTemplates>
<f:Features>
<f:DeviceType name="MyNewDevice">
<f:FR ref="MyNewDevice"/>
</f:DeviceType>
</f:Features>
</DefaultMeasurements>

4. Create the OPC mapping between the MT tags to add desired measurements that will be exposed to OPC. The attached file can be used as an example. A simple single measurement would have the following information

<Ctxt label="Energy" >
<Ctxt label="Real Energy">
<M name="Real Energy Signed" label="Real Energy Signed" />
</Ctxt>
</Ctxt>

5. Once finished mapping the OPC points, save the file and close the text editor.
6. Use Management Console to Update the OPC Server again and confirm the desired device is now available.
