Power up
• 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.
• Count - Only available when Interval, Specific Days or Month End are selected as a
Sub Type. This is how often you want this to occur. The recorder will carry on with this
schedule for the amount entered in the count. Eg. If 24 is entered into the count the
scheduled event will occur at the specified time for 24 hours. A count of zero will carry
on indefinately.
• Days of the Week - Only available when Specific Days is selected as a Sub Type.
Select the days of the week when this scheduled event is to occur.
• Time of Day - Only available when Specific Days is selected as a Sub Type. Select the
Time Of Day when this scheduled event is to occur.
User Counters
User Counters are quite simply counters that are set up by the user. User Counters can be
used as a Cause to trigger an Event Effect. The User Counter information must be setup in
the before it can be used as a part of the event system.
See “Counters Menu” on
page 89 .
For a User Counter to be used as a Cause, a User Counter must already be set up and be
counting something. eg. a User Counter as an Effect of another Event.
