June 23, 2008 - Exele TopView 6.2.5 Release for OPC, PI, and PerfMon Alarms, Notification and Remote Monitoring for OPC/SCADA/PI Process data and System Performance (PerfMon).
Alarm limit deadband
The optional alarm limit deadband can be used to change the "return-to-normal" value for comparison limit conditions. Once the limit value is violated, the tag value must move outside the bounds of the limit value +/- the deadband in order to return to normal.
Deadband Examples:
- Condition: >, Value: 50, Deadband: 5The condition will be TRUE when the value is > 50, but it must then move below 45 to be FALSE
- Condition: <, Value: -20, Deadband: 3The condition will be TRUE when the value is < -20, but it must then move above -17 to be FALSE Alarm/Point priorities Each monitored point (and its set of alarm conditions) can be now be assigned a priority number from 1...10.
- 1 = High priority
- 10 = Low priorityThe priority setting is used throughout TopView
- DisplayThe TopView Window, HTML output, and Remote Viewer can optionally display the priority value for each monitored item in a new column.
- Filter The TopView Window and the Remote Viewer can filter the displayed items using the new priority setting: show items with priority <= "Max Priority" where "Max Priority" is set by the user.
- Notification queue processingThe priority setting will also affect the processing of the Email, Modem, and Voice notification queues.
The items with highest priority will be processed before items with lower priority.
Contact Aliases
A Contact Alias "points to" an existing Contact.
Once a Contact Aliases is created, it can be used like a Contact to designate a notification recipient.
When TopView is running and needs to notify a recipient that has been specified using a Contact Alias name, the Alias will be resolved to the Contact that it is currently assigned to and the appropriate field of the assigned Contact (email, phone, pager) will be used.Contact Aliases can be used in situations where recipients may change and you would like to minimize the configuration changes required.
If you specify notification recipients using Contact Aliases instead of Contacts, you will only need to re-point the Contact Alias when the recipient changes.
