Power Monitoring Expert - Why doesn't auto-diagram work for my custom device created in the Modbus Device Importer?

Published date: 13 November 2019

'Add "Generate Network Diagram" Support' in the Modbus Device Importer does not write to the DeviceInfo registry key, and thus Vista 'auto-diagram' will not work.

Modbus Device importer (MDI)

User running the MDI program does not have permission to write to the registry


To correct this problem, either populate the Registry manually (not recommended) or launch MDI as user with permissions to write to the registry and re-run the 'Add "Generate Network Diagram" Support' menu item.

1) Locate the ModbusDeviceImporter in [PME install folder]\system\bin
2) Right click and select "Run as administrator"

Note: In PME 9, Device Type Editor (DTE) is used to add diagram support. The DTE may also need to be run as Administrator
