 Device Grouping Locate this document in the navigation structure

Purpose

In this component you can group together devices that form a logical unit. All devices in a device group must currently either be installed or not installed.

If you install or remove a device in a device group , all other devices in the group are automatically drawn for removal or installation. This ensures that devices that belong together are not accidentally installed or removed. You must confirm the replacement of each device in a device group.

Implementation considerations

This component is optional. You should create a device group if, for example,

  • Current and voltage transformers are placed into transformer groups, resulting in a certain transformation ratio.

  • Two water meters are installed together as one integrated water meter.

Features

You can:

  • Maintain and display the history of the device group

When you do this, you can change the current time slice. You can decide whether the device group is to be prorated to the change date, that is, whether you wish to start a new time slice. You can display change documents and creation data.

  • Inspect the device group

The system checks the device group for general and special restrictions. For more information, see the online help for the following fields:

  • Device group

  • Group type

  • Group category

  • Terminate the device group.

When you terminate a device group, all devices are removed from the group. The device group is empty and can be used for new devices.

  • Delete the device group.

When you delete a device group, it is deleted from the system entirely.
