Setting a Polling Group within AssetWorX allows users to define set data polling characteristics that can be connected to individual assets (either Equipment or Equipment Classes).
To Add a Polling Group
Expand your AssetWorX database ( localhost > [the name of your AssetWorX database. In our examples, we've named it 'AssetWorX'] > System properties) to show the 'Polling groups' branch.
Right-click on the 'Polling groups' branch and select 'Add PollingGroup' OR select the Polling Groups branch in the asset tree and then, once the contextual ribbon changes to the items relevant to your item selection, click on the 'Add Polling group' button in the Edit section of the Home ribbon. Both methods are highlighted in the image below.
'Add PollingGroup' in AssetWorX
This will open a [NewPollingGroup] tab in the right-side window of the Workbench, as well as a placeholder in the top right items list. This items list shows any sub-items connected to an asset, as well as any of its connected properties. Give your polling group a name and description (We have called our example 'Polling Group Alpha').
Polling Group Properties in AssetWorX
The following options can be set for the polling group:
Scan rate - When the Property is a normal Dynamic Tag, the scan rate is not specified by the configuration. It is specified by the client that connects to the Property. Until a client requests a Property, it is not on scan. When the polling mechanism subscribes (for a brief period) to the polled tag, it will use this Scan Rate. It has not much effect though, as the polling mechanism unsubscribes shortly after receiving the first update. Set in milliseconds.
Read timeout - How long the polling mechanism waits to get the first (good) value from the input source. Set in milliseconds.
Group splitting - The polling mechanism will subscribe, at a maximum, to this many tags at once, even if more Asset Catalog Properties are in the same polling group.
Recurrence type - The pulldown menu allows you to set the period of recurrence. The options include One time only, Time interval and Specific dates and times. The remainder of the Polling Group properties changes based on what Recurrent type you select.
One time only - Once you set the pulldown menu to 'One time only', you'll be able to enter the specific date and time in the 'Trigger at:' field directly or via the calendar tool (by clicking on the 
button). Clicking on the button brings up the calendar tool as shown in the image below. Select your date in the left side and the time in the time in the right side, then click on 'Close' to return to the main Polling Group properties screen.
'One time only' Settings
Time interval - Once you set the pulldown menu to 'Interval', you'll be able to enter the specific date and time in the 'Trigger at:' field directly or via the calendar tool (by clicking on the button), similar to the 'One time only' selection above. You will also be able to set the recurrence period by filling in the 'Recur every:' field. [NOTE: The format of the ‘Recur every’ field is: Day.Hour:Min:Seconds.] Highlight any portion of the time and you can use the up and down arrows to edit in increments.
