Npoints > 1 – Dead-band from average value. An alarm report is sent when a new
I/O value differs from the average of the previous <Npoints> values by more then the
dead-band.
Disable a dead-band alarm by setting the alarm dead-band value to zero.
3.5 Scheduling
Scheduling is one of the most important features of the PAC. Two important scheduling
concepts are start time and interval time.
Start Time - This is the date and time the PAC will start the event. This is usually set in the
past so the event will start immediately. It can be set in the future if necessary, but this is not
recommended.
Interval time - The interval determines how frequently the PAC will execute an event,
beginning from the start time.
Two types of events to schedule in the PAC are polls and reports.
A poll event causes the PAC to request data from an end-device. If low power is enabled the
PAC will sleep in between polls to conserve power. The poll interval depends on how time
critical it is to know of changes in the data being polled versus the available power on site.
A report event causes the PAC to poll for the latest values and send the values to IP
Anywhere.
The following commands are used to configure an event.
EVENT SET <index> <type> <pid> <start> <interval> – This command will create a new
event or modify of an existing event.
Index There are 16 available event records, 1 - 16 are valid
Type Available event types are
POLL - Read IO Pollset
REPORT - Read IO Pollset, and
STATUS - Request status from NET (communicator)
REBOOT - Restart application.
PID For POLL/REPORT events, a pollset id must be specified. For
STATUS/REBOOT events, no PID should be given.
Start The start time for the event. Long format:
MM/DD/YY HH:MM:SS
Where: MM = month (1-12); DD = day (1-31); YY = year (00-99); HH
= hour (00-23); MM = minute (00-59); SS=seconds (00-59)
