Destinations

 

A Destination is a location that can receive reports. A Destination is most commonly a telephone number but other possibilities exist.

 

Destination types include:

 

 

 

Destinations are not to be confused with Destination Net Addresses (DNAs).  Destinations receive reports only upon occurrence of specific conditions (such as scheduled intervals), whereas DNAs are continuously updated with the current value of the channel, at the scan rate of the RTU.

 

Destination Parameters:

 

 

Destination Numbers:

 

The Destination Number is an ordinal number used to identify specific Destinations in configuration work.  The choice of Destination Number can be important from the following standpoint:

 

Destination Numbers also are related to the priority in which reports are delivered.  If a single channel is in Unacknowledged Alarm, reports will be sent to destinations based upon a priority of lowest Destination number first. 

 

If more than one channel is in Unacknowledged Alarm, then by factory default, reports are delivered on the basis of lowest Destination number first.  However, you may choose instead to have the report delivery priority based primarily upon lowest channel number rather than lowest Destination number.  From Alarmware™, this setting appears under the Configuration | Session Parameters menu.

 

Input channels can be individually assigned to call all destinations, single destinations, or groups of destinations. See Destination Channel Grouping

 

Destination use of Devices and Protocols

 

Destinations utilize devices and protocols as resources to carry out sessions. Devices usually consist of hardware within the RTU, such as: the date and time clock (TOD), the data/fax/voice modem, local serial ports, and miscellaneous inputs and outputs. Protocols are similar to languages. Protocols are the agreed upon languages which machines use to talk to each other, fax machines for example.
