Product Line
Power Monitoring Expert 9.0
Power Monitoring Expert 2020
Power Monitoring Expert 2021
Power Monitoring Expert 2022

Environment
Device Type Editor

Cause
Although OPC Sites can be added within Management Console, OPC devices do not have a native device type and require a custom configuration.

Resolution
For PME 8.2 and earlier please see the following article: Video: How to create custom OPC DA Device Types in SPM and PME

To create an OPC device type:

In Device Type Editor, click File > New > OPC Device Type to open a New Mapping template.
Enter the OPC tag information into the OPC Map table in the right display pane, in one of two ways:
- Add each tag manually in the Device Type Editor, using the available editing controls.
- Use Microsoft Excel to define the tag list, copy it, and paste it into the OPC Map table.

NOTE: When entering a tag, only specify the tag name, with a leading period (.), do not include the OPC server or device name. For example, for the tag Opcda://Server/OpcDa.1.Channel_1.Powers.Real_Power enter ".Powers.Real_Power" as the tag name in the OPC Map.

Map each OPC tag in the OPC Map to a measurement in the Measurement Tree in the left pane. To see the measurements in the tree, expand the managers and modules, for example Current > Phase Current > Current A,B,C, ... . Map the tags in one of two ways:
- Using the mouse, drag the measurement you want to map in the Measurement Tree onto the corresponding tag in the OPC Map.
- Using the mouse, drag the OPC tag you want to map in the Modbus OPC Map onto the corresponding measurement in the Measurement Tree.

NOTE: If you cannot find a suitable measurement in the Measurement Tree, add a new manager, module, and register to represent this measurement. To do this, right-click any of the existing managers in the Measurement Tree and choose the appropriate menu options.

Configure the device type name and template name.

In the Measurement Tree, click Factory Information > Factory 1 > FAC1 Device Type to open the String Register Details dialog for this register. In String Register Details, enter a device type name in the Value box. This name will be visible in the Management Console when you select a device type for a new device. Choose a name that identifies the OPC server, but does not match any of the existing device types. Example: Use "OPC_ABC" as the device type name, where ABC identifies the server.

(Optional) Click Tools > Clean Measurement Tree to remove any Measurement Tree elements that have not been mapped to OPC tags. This makes it easier to find the relevant measurements in the Measurement Tree in Vista or an OPC client for example.
Click File > Save, to save the new device type.

Note: The best practice to add custom measurements to PME is to add them with Manual Data Editor first. For more information please see What is the best practice to add custom measurement in PME?
