Understand two-character application IDs

When you export alarm and tag comments for localization, you must specify a two-character application ID. The ID is used internally by the system to distinguish between alarms generated by applications having the same name.

Because a tag can contain both a tag comment and an alarm comment, 1 and 2 are added after the two-character application ID to differentiate between these two fields. Tag comments have a 1 between the ID and the tag name. Alarm comments have a 2 between the ID and the tag name. For example, AA1TankLevel is a tag comment, and AA2TankLevel is an alarm comment.

If you export an application, the application ID information is removed.

If the alarm database contains old data without a two-character application ID and new records are prefixed with an ID, then alarm comment queries in the Alarm DB View control do not work with the following operators: <, <=, >, and >=.
