EcoStruxure Web Services (EWS) configurations

By default, the EWS service is disabled in PME 8.2.

If EWS is configured on the 7.2.2 old system, it must be re-enabled in the new 8.2 system.

To check for EWS customization on the old system:

1. In Windows Explorer navigate to …\Schneider Electric\Power Monitoring Expert\Applications\EWS\ and then open Web.config.
2. Search for the following string:
• EWSEnabled

• If the EWSEnabled value is 1, then EWS is configured. If the value is 0, then it has not been enabled and does need to be updated in the new system.

3. If EWS is enabled, search for the following settings:
   • EWSAlarmSortOrder
   • ContainerItemStructure
   • DisplayNanValueNaNValue
   • ConcatSourceAlarmEventId
   • RealTimeRefreshRate
   • RefreshImmediately
   • RealTimeSessions
   • IgnoreCurrentCulture
4. Note the setting values; you will need to copy these to the EWS configuration on new system.

To transfer any custom EWS device type definitions:

1. In Windows Explorer navigate to ...\Schneider Electric\Power Monitoring Expert\system\WebServices\Extensions\.
2. Copy the Extensions folder to ...\SBS Upgrade Package\EWS.
