 Device Replacement Locate this document in the navigation structure

Purpose

This process enables you to replace devices.

Example Example

You replace a double-rate meter as part of a periodic replacement or due to damage.

( )

You can replace devices that have different measuring types. However, you may have to change the measuring types in the device allocation data.

End of the example.

Prerequisites

  • When you enter the replacement, the device must not have been modified or changed in the system after the actual replacement date. The entry in the system must correspond to the actual history of the processes.

Example Example

You enter the installation on 10/12. The installation took place on 10/08. A device modification or a change to the device data may not have been entered after 10/08.

End of the example.

  • The same prerequisites apply to the device to be removed as to the removal of a piece of equipment ( Device ) from a functional location ( Device location ) in the Plant Maintenance (PM) application component.

  • The same prerequisites apply to the device to be installed as to the installation of a piece of equipment (device) in a functional location (device location) in the Plant Maintenance application component.

For more information see the following in the Technical Objects (PM-EQM) application component:

Process flow

Device replacement includes the following phases:

  1. A replacement order is created for a device or a device group in the Service Management (PM-SMA) application component. This may result from a company requirement (such as a switching change) or an external requirement (such as a change in use of the object).

  2. The replacement order is executed and confirmed.

  3. The replacement of the device or of all devices in a device group is entered in IS-U.

For more information, see Installing, Removing, and Replacing Devices

Note Note

There are different replacement scenarios for device groups, such as Replacement of a device group with another device group .

Note that replacement orders can only be created for single devices. This means that if the device belongs to a device group, the other devices are not transferred to the order automatically as additional items.

( )

The system automatically checks and prorates the attributes (such as measured pressure, billing factor, or command) of existing device allocations. A message is displayed if the system cannot check attributes automatically. You can go directly to the device allocation and check attributes manually. To do this, choose   Goto   Device allocations   .

End of the note.

Result

The new device adopts all relationships of the old device. If device categories of the devices do not match, it is possible that individual relationships were prorated.
