process, some of the “satellite-delivered” Compel commands would not make sense and are not
supplied, such as many of the Action commands, the Time-of-Day command, and satellite File
Download operations.
For Compel control, the unit indications are:
1. COMPEL LED (some units “NETWORK”) ON if Compel server is responding,
flashing briefly when “personally” addressed commands are received
The user control interfaces feature the following controls. The user (with debug access) or
the factory is the preferred command method:
1. Compel internet server IP address
2. Poll time
Local Scheduler
The Local Scheduler is a database that holds and stores Compel commands each for
execution at a pre-specified date and time. This allows Compel to assure itself that receiver’s
will all execute a particular function at a specific time, regardless of the availability of Compel
command stream at that time. To distinguish the different missions that sets of Compel
command might perform, each stored Command has a “priority” code.
The user control interfaces feature the following controls. Compel is the preferred
command method:
1. Add schedule line (Compel command, date/time, and command priority)
2. Delete schedule lines (by command priority)
3. Delete all schedule lines
Triggers
Triggers are similar to the Local Scheduler, but instead of executing stored Compel
command at a specific time, the commands are executed at the moment a special Event occurs.
Two types of such events apply: One are closures on the iPump6420s PIO inputs, the other is
the Compel TRIGGER command. In each case, the Trigger is assigned ahead of time, by local
user or Compel, then the event forces the execution through the Trigger mechanism. Triggers
may be Temporary (“one-shot”) or Permanent. A Temporary Trigger will accept the triggering
event, execute the stored command, and then will no longer respond on subsequent triggering
events. The Permanent Trigger, on the other hand will cause stored Compel command execution
on each and every triggered event.
Triggers are assigned a simple number codes, 0 to 255. Any number code from 0 to 6 may
be assigned to the local PIO trigger closures. Any number from 1 to 255 may be assigned to
Compel TRIGGER commands. Note that numbers from 1 to 6 have a dual role, and either local
PIO or Compel TRIGGER commands will “fire” them.
The user control interfaces features the following commands. Compel is the preferred
command method:
1. Create Temporary or Permanent Triggers, 0 to 255, assigning them to a specific
Compel command.
2. Compel trigger command or PIO closure
3. Delete Triggers
4. Abort temporary trigger.
