#### Device Diagram Customizations

Issue: Customizations to default device diagrams are lost when the diagrams were moved to the new system.

Cause: This issue can occur when a customized default device diagram on the old ION Enterprise system is configured to open from a grouping object that has the “Action” set to “Open Diagram for Meter Template”.

This option will use an automatic mechanism in ION Enterprise to find the default device diagram based on the device type, firmware versions, and other settings. If the new PME system has an updated version of the default device diagram and the automatic mechanism is used to discover it, then the new one will be opened which does not have the customizations.

Workaround:

Option 1: Change the links on the new system to link to the specific default device diagram that was transferred over from the old system. Choose the option “Open User Diagram” in the dialog and then select the relevant diagram from the old system. The advantage here is that this requires relatively little time and effort. The downside is that you will not get the benefit of any bug fixes that led to the creation of the new diagrams.

Option 2: Copy the customizations that were done to the old diagram to the new diagram in PME 8.2. The advantage here is that you get any bug fixes that triggered the creation of the new diagrams. The downside is that you have to manually recreate the customization.
