Device group definitions

The Device Groups dialog box, which is displayed by clicking the Device Groups tab in the New_<Name>PLC_000 Parameters configuration view, is used to perform the following activities:

• Adding, defining, and deleting device groups.

  Note: When you add a new device group, enter a unique name.

• Configuring default update intervals.

• Editing update intervals for the objects.

  Note: When you select another part of the Communication Driver tree hierarchy, you are prompted to save the modifications to the configuration set.

Create or add device groups

1. Right-click in the Device Groups dialog box.

2. Select the Add command from the shortcut menu.

   • When you add a new device group, enter a unique name (up to 32 characters long).

Make edits on device groups

Make edits on a device group’s name or update interval for an object as follows:

• In the Name column, double-click on the device group’s name to be edited and make the edit.

• Double-click on the device group’s value to be edited in the Update Interval column, and make the edit.

Delete device groups

Deleting a device group from the list can be performed as follows:

3. Right-click on the device group to be deleted.

4. Select the Delete command from the shortcut menu.

Note: When you select another part of the ABTCP Communication Driver tree hierarchy, you are prompted to save the modifications to the configuration set.

Configure default update intervals

5. To configure a default update interval for the object, right-click in the Device Groups dialog box.

6. Select Config Default Update Interval from the shortcut menu.

Edit update intervals

• To edit the update interval for an object, double-click its value in the Update Interval column and make the edit.

  • Update Interval is the frequency (in milliseconds) that the Communication Driver acquires data from the topics associated with that device group.

  • Different topics can be polled at different rates in a PLC by defining multiple device-group names for the same PLC and setting a different Update Interval for each device group.

    Note: When you select another part of the ABTCP Communication Driver tree hierarchy, you are prompted to save the modifications to the configuration set.

Each configuration view associated with nodes/objects in the Communication Driver hierarchy tree has a common feature, the Save button.

7. When you modify any parameters in the Device Groups dialog box, click Save to save and implement the new modifications.

   • If you do not click Save, the configuration is reset to its original condition (since the last save).

8. After all modifications, you must save when prompted for the new data to be saved to the configuration set.
