There are a few techniques that can be used. You can use Security to limit access to certain points and alarms to specific users and user groups. You can also use the Alarm properties of the Alarm Area, Alarm Group and Alarm Category to filter on in the Alarm Viewer.
To use Sinolta Security configuration to control visibility/Read-Only/Read Write assign to each point.Users with no visibility will not see the alarms; users with Read-Only will see the alarms but will not be able to acknowledge or reset the alarms. Users with Write access can rest to acknowledge the alarms.
Alternatively, alarm viewers can be set up with filtering to display on those alarms that are in the Area of Responsibility for a user by defining an Alarm Area, Alarm Group or Alarm Category for a group of users.
