• Enabled - Tick to enable
• Type - Scheduled
• Sub Type - Set Once, Interval, Specific Days or Month End
Once – This is a once only occurrence
Interval - A scheduled can be setup at timed intervals eg. every 12 hours.
Specific days - Select the day(s), time and how often (count) the schedule will occur
Eg. Friday at 12.00 with a count of 10 will carry on for 10 weeks or Monday through to
Friday at 12.00 with a count of 10 will carry on for two weeks.
Month End - If Month End is selected with a count of 10 it will carry on for 10 months.
The recorder refers to a built in calendar and clock and will schedule the event to occur
at midnight on the last day of each month.
• Date/Time - Only available when Once is selected as a Sub Type. Select the time and
date for a one off occurrence.
• Period - Only available when Interval is selected as a Sub Type. Set the time interval
for how often this event should occur, eg. every hour would be 1h:00m:00s
• Alignment - Only available when Interval is selected as a Sub Type. Select and enter a
value from the list to align the scheduled event at specific intervals.
For certain applications it maybe desirable for a relatively fast schedule interval event,
for example every 10 minutes, to be aligned with a particular time. For example on the
hour.
When the alignment function is not used, the schedule interval starts immediately on
committing the configuration. When the alignment function is used, the schedule inter-
val starts when the first interval event coincides with a subsequent interval that lines up
with the desired alignment ie. Top of the hour.
Figure 4.9 shows if a 10 minutes schedule is required to align with a whole hour, and the
configuration is committed at 17 minutes past, the recorder will wait until 20 past before
starting the schedule interval. As starting at 20 past with 10 minute increments will ensure
alignment with a whole hour.
