What is a measuring point?

In Sedrix, a measuring point is used to display and analyze measured data.

All measuring points are made up of the following:

Input channels
These result from the raw data assigned to the data sources
Function blocks
These are used to perform calculations with input channels
Output channels
These are the calculation results from the function blocks
Evaluation views
These are various definable views or summaries to display data online, in reports or in export formats.

A measuring point is used to logically group individual measured variables. The measurement data is linked to devices and data sources via assignments.

The logical criteria used to assign measurement data to measuring points depends on the respective application and is completely up to you.

Examples of possible groupings:

Type of grouping	Description	Examples
Measurement location	All measured data from one location is pooled in one measuring point. This is particularly useful if measuring points are to displayed on a plan or map.	Vibration measurements: Interval data and events are assigned to a measuring point, so that one measuring point corresponds to one vibration measurement device placed in the field.
Measuring object	All measured data from one measuring object are pooled in one measuring point.	Geodetic measurements: All measured data of the track section or overhead line mast being inspected. Measurements with an inclinometer probe: All measured data from a borehole belongs to one measuring point
Measurement system	All measured data of a measurement system, e.g. a water level gauge, is pooled in one measuring point.	All data from a chain inclinometer is assigned to a measuring point. A corresponding function block is used to evaluate it.
Sensor type	The measured data is pooled in one measuring point according to sensor type.	A group of position sensors in a multi-point extensometer.

The data in a measuring point can come from several different data sources, depending on the criteria used to assign the data.

BEST PRACTICE

As a rule, it does not make sense to create a measuring point for each measuring channel of a data source.
Measuring channels that are to be offset against each other using a function block must always be assigned to the same measuring points.
