Interval

This object is used by the Tag Group object to determine the rate at which the contained tags are polled. Each Tag Group object requires an Interval, so it is advised that you create this before creating the Tag Group.

Configuration

Default settings for the Interval Object

Property	Description

Property	Description
Name	The name of this item. Names must be unique in eACM.
Description	A description of this Interval Object can be included. This is an optional field that does not affect the use of this object.
Poll Interval	The time between polls. The behavior changes depending on if Start Time is enabled or disabled: If Start Time is enabled, the poll interval is scheduled based on the given Start Time. See the provided example for more information. If Start Time is disabled, the poll interval is scheduled based on when polling first initiates. The time will dynamically change when different units are selected (e.g. 5 Seconds will become 5000 Milliseconds).
Start Time UTC (hh:mm:ss)	The coordinated universal time (UTC) that polling is scheduled on. This Start Time is only followed if Enable Start Time is selected.
Enable Start Time	If enabled, you can modify the Start Time and that Start Time will be followed. If this property is disabled, the Start Time is ignored and polling can begin immediately.

Start Time Enabled Example:

To poll a site once every 5 minutes you could use this configuration:

A Tag group assigned this interval is scheduled to poll every 5 minutes

Possible poll times are {08:00:00, 08:05:00, 08:10:00, … 23:55:00, 00:00:00, … 07:55:00}. If you start the device at 02:03:00, the first poll won’t start until 02:05:00 because that is the next available poll time.

To schedule polling for every 8 Hours based on a starting time of 8:00 UTC, you could use this configuration:

Possible poll times are {08:00:00, 16:00:00, 00:00:00}. If you start the device at 21:00:00 UTC, the first poll won’t happen until 00:00:00 UTC because that is the next available poll time.

Start Time Disabled Example:
To schedule polling every 8 hours from when the device first polls, you could use this configuration:

If it is 04:12:30 UTC when I start my device, the poll times are {04:12:30, 12:12:30, 20:12:30}. If I restart the device at 06:21:05 UTC, the poll times scheduled are now {06:21:05, 14:21:05, 22:21:05}.
