Why restoring PI Server ID?
Before restoring an ME module configuration from a backup file, you should decide whether you want to restore its PI Server ID (ServerID) or not.
TIP:
- If different modules have the same ServerID, client applications such as DataLink may connect to other modules than expected.
- On theBackup and Restorepage,Current ValueandRestore Valueare always set toN/A. Whether the ServerID is restored or not depends on the setting of theServerIDcheckbox.
Consider the following use cases:
Use case 1
You have created a backup of the configuration of an ME module. The module gets damaged. You take out the broken module and replace it with a new one. You restore the backup files of the broken module on the new module. While configuring the restore process, you leave the
ServerID
checkbox selected, because you want the new module to have the ServerID of the original module. PI Server ID will be restored with the configuration.Use case 2
You want to copy the configuration of one of your ME modules (Module 1) to other ME modules
that will function simultaneously along with Module 1. You create a backup of the Module 1
configuration and restore it on the other modules. While configuring the restore process,
you clear the
ServerID
checkbox, because you don't want to replace PI Server IDs of
these modules with the Module 1 ID. PI Server ID won't be restored with the
configuration.Provide Feedback
