How to change a device connection type from serial to ethernet while retaining data in PME

Published date: 26 March 2019

The device connection was connected serially using an ethernet gateway and now it's directly connected using ethernet. The user would like to change the connection type while retaining the historical data in PME 8.0.

Production Line
ION Enterprise 4.x, 5.x, 6.x
Struxureware Power Monitoring 7.0.1
Power Monitoring Expert 7.2.x, 8.x, 9.0

Management Console 

To change the connection type:
  1. Back up the ION_Network, ION_Data and ApplicationModules databases, just in case something goes wrong.
  2. Stop all the ION and Application Module services
  3. Note down the device name (Group.Name) for example: MainBuilding.Feeder1.
  1. Delete the serial device from management console by right clicking on the device in the device list.
  1. Re-add the device as an ethernet device making sure that the group and name are exactly the same. In this example : MainBuilding.Feeder1.
  1. Restart the ION and ApplicationModules services.
The Log Inserter will use the existing entries in the Source table (ION_Data), SRC_Source table (ION_Network) and DataSourceBus.DataSourceDevice/DataSourceBus.LogicalDevice tables (ApplicationModules) so that the historical data will be continuous and everything referencing this device will carry on as it did before.
