Working with Reference Measuring Points 

Use

The assignment of reference measuring points to reference functional locations ensures that creating and changing functional locations is quick, easy, and error-free.

Prerequisites

You have created reference functional locations and, if necessary, mapped hierarchies.

In Customizing, you defined the applicable measuring point types under Measuring Points, Counters, and Measurement Documents.

You used the class system to create the characteristics that you want to assign to the reference measuring points.

If you want to qualitatively evaluate measurement and counter readings, in the system you must have created the code groups you specify in the master records of measuring points and counters for this purpose.

Features

General

You can create, change, and display reference measuring points. When you create a reference measuring point, always refer to a reference functional location. If functional locations are already assigned to the reference functional location, then when the reference measuring point is saved, the system automatically creates as many measuring points as there are assigned functional locations.

On the one hand, there are fields that are just copied to the measuring points once when a reference measuring point is created. On the other hand, there are fields that are copied as reference when a reference measuring point is created. These are the following fields:

·        Measurement position

·        Characteristic name

·        Target values

·        Text

·        Code group

·        Measurement value transfer

The contents of these fields are then copied into the measuring points as reference, if you have filled the fields when you created the reference measuring point.

You can define the logic of the measurement value transfer on the additional data screen in the reference measuring point.

Measuring points

If data from a reference measuring point was copied into measuring points as a reference, you can use List Data Origin in the measuring points to see that the data comes from the reference measuring point. If you do not fill the above fields when you create the reference measuring point, or if you later manually change the field contents in the measuring point, then these fields are marked as individually maintained in the List Data Origin.

In the measuring point, you can change the assigned reference measuring point, and add or remove the reference to a reference measuring point.

You can define the logic of the measurement value transfer on the additional data screen in the measuring point.

Reference Functional Locations

You can also use the reference functional location to create, change, and display reference measuring points.

You can branch from the individual processing of reference functional locations to an overview screen of the reference measuring points and process individual reference measuring points. You can branch from a reference measuring point to the measuring point processing.

You can use the list editing of reference functional locations as a worklist and process the reference measuring points, location by location.

You can display the assigned reference measuring points from the structural display of the reference functional locations.

Functional locations

You can process measuring points and display their corresponding reference measuring points from the individual- and list processing of functional locations. When you create functional locations with a reference functional location as template, you can automatically create measuring points, if reference measuring points are assigned to the reference functional location.

In the functional location itself, you can use the data origin to see whether the data for the measuring point was maintained individually or comes from the reference measuring point. You can display the reference measuring points from the measuring points.

Measurement reading transfer

When you construct a reference measuring point hierarchy you define the logic by which the measuring points are transferred within the measuring point hierarchy. This logic corresponds to the logic of the measurement reading transfer in the measuring points (see Transfer of Measurement Values and Counter Readings).

The logic of the measurement reading transfer is only bequeathed centrally to the measuring points when reference measuring points are created. A central change of the measurement reading transfer logic in the reference measuring point is not supported. This means that you always make changes to the transfer logic directly at the technical object.

If you have activated interval documents in Customizing, and you create a counter with reference to a reference counter, then each counter is created such that the counter readings are later always transferred in an interval document. However, you can manually convert the counter reading transfer to a single document for each counter.

For more information on the measurement reading transfer, see Processing Reference Measuring Points and Settings and Setting and Displaying Functions in Measuring Points.

You cannot assign equipment to reference measuring points.

You cannot create measurement documents for reference measuring points.
