Using Realm Area Filtering to Restrict User Access to Groups of Alarms

Some applications (such as those that service users from multiple plants or companies) require that when an operator dials in, alarms are filtered based on their Area property, such that the operator is only informed about those alarms that are pertinent to his or her duties.

Realm area filtering is described in detail in the VTS Programmer’s Guide (see: Realm Area Filtering).
