Instructions to complete the CALL COLLECTION - POLLING SCHEDULE
WORKSHEET:
1.
Make as many copies of this worksheet as needed.
2.
Plan a complete schedule. (This is particularly important in a multi-site configuration,
in which many sites are polled through the same port.)
a.
Use a “scratch” sheet for a single PC serial port. Divide the days
(weekday/weekend) into non-overlapping hour or half-hour slots and assign
them to a site. For example:
Port Used
Start / End Times
Days = Weekdays (M-F)
OR Weekend (Sat-Sun)
Site Name
for polling
00:00 - 00:59
sites:
01:00 - 01:59
02:00 - 02:59
03:00 - 03:59
04:00 - 04:59
05:00 - 05:59
06:00 - 06:59
07:00 - 07:59
08:00 - 08:59
09:00 - 09:59
10:00 - 10:59
11:00 - 11:59
12:00 - 12:59
13:00 - 13:59
14:00 - 14:59
15:00 - 15:59
16:00 - 16:59
17:00 - 17:59
18:00 - 18:59
19:00 - 19:59
20:00 - 20:59
21:00 - 21:59
22:00 - 22:59
23:00 - 23:59
b.
Once the schedule for weekdays and for weekends for the port is established,
pass the port information to the
CALL COLLECTION INTERFACE WORKSHEET
and the time-slot information from your “scratch” sheet to the
CALL COLLECTION
- POLLING SCHEDULE WORKSHEET
, one site at a time.
3.
Select and/or enter:
Name of the site and port used.
Weekday or Weekend (not both). If Weekday, the site is polled Monday through
Friday in the specified manner; if Weekend, the site is polled Saturdays and
Sundays.
The start and end times (use 24-hour clock notation). These set the time-slot in
which a site has claim to that port. If a poll should run over its time-slot, it will be
terminated (the remainder of the data will be retrieved on the next poll). Once a
poll ends, the next site with a time-slot claim to that port will be polled.
Polling cycle — a single poll or polls at periodic intervals. If you select single poll,
the site is polled once, at the start time; if you select periodic polls, enter the
