As the name says, this profile type is used for general time-based recording. The profile stores measured data with equidistant samples. The type is available by default and can be used for the following types of data store:

  • Time-based data store

  • ibaHD time-based data store

  • Kafka cluster time-based data store

  • MindSphere time-based data store

  • MQTT time-based data store

  • InfluxDB time-based data store

Profile properties

Type

Display of the profile type with the appropriate types of data store (symbols)

Name

Enter an unambiguous and understandable name here.

Time base

Choose whether you like to record the acquired data with the original time base (as configured under General settings in the I/O Manager) or with another time base (absolute time base). If you select Absolute time base, please define the desired time base in the field, given in milliseconds.

Upper limit value is 214748 (approx. 3.58 min.)

If you decide to use a Relative timebase, enter or set an integer factor to get a multiple of the original timebase. Upper limit is 100,000.

Filter

Select the signal value to be stored with reference to the time base set above.

  • None: The actual value will be stored

  • Average: The arithmetic average of all measured values, which were acquired in the interval (according to the time base, such as 10 ms or 100 ms) is formed and saved.

  • Min: Only the smallest value of all samples measured within the defined interval will be stored.

  • Max: Only the largest measured value of all measured values acquired within the defined interval will be stored.

Compression with precision

Use this option to achieve a further reduction in data. Method: every value is subtracted from the previous one. The (absolute) difference is compared to the accuracy value defined in the field nearby. The new sample will only be stored if the difference exceeds the accuracy value (based on the physical unit of the signal). If the difference is equal or less than the accuracy value, an internal counter in the data file will be incremented and the sample will not be stored. Storage space can be saved thereby. Usually, this method is suitable for signals with a general noise or for sensors with less accuracy. The accuracy value indicates the absolute range given in physical units in which a signal sample can vary without being stored as a new value.
