About data sources and devices

Data sources provide operational data to the portal at regular intervals, for example measured values from your devices on site. Setting up a data source means connecting the portal to an external system, such as a data logger, a manufacturer portal, or another data import method. Once connected, the portal automatically imports data and can create system devices based on the imported information. Without a data source, almost nothing can be monitored or calculated in the portal.

Note

It is possible to add multiple data sources for a single system. Exception: very old data sources.

Types of data sources

The portal supports different types of data sources to accommodate various setups. The appropriate data source depends on how your system provides data.

Compatible data sources

The import compatibility list shows which manufacturers and platforms are directly compatible with the portal and can be added right away. Use the list to verify support for your data source and review further import configurations.

Alternative data sources

If your data source setup is not directly supported, you can still import data using the following alternative integration options:

Types of intervals for data sources

Measuring interval

The measuring interval is the frequency at which individual values for each data point are provided by the data source.

  • Usually, this interval is fixed and determined by the data source.

Example

A data logger may log values every 5 minutes, while another data source provides values every 15 minutes.

  • You enter the respective interval during data source setup. The set interval applies to all data sources of the same type.

Example

If you have two bluelog Neos on site, you can not enter two different measuring intervals for them.

  • “Irregular” time stamps are synchronized to fit the measuring interval.

Example

If a data logger sends a data point measured at 12:11, and another sends one for 12:13, the portal syncs both time stamps to 12:15.

Data sources supporting 1-minute values

  • If your device supports measured intervals of 1 min, you set the interval to which the data should be aggregated after the storage period for 1-minute values expires. See also Data resolutions and storage periods.

  • BLUELOG ONLY For bluelogs, the measuring interval is displayed as [x] min (aggregated) by default, because bluelogs always support 1-minute values.

Multiple data sources with different measuring intervals

In general, multiple data sources with different measuring intervals are supported. However, this may lead to the following minor limitations:

  • Smart alarms: Time-based alarm evaluations may be affected if involved data sources provide data at different intervals. If a data source is not relevant for alarm timing, consider excluding it from smart alarm calculations. See Ignore data sources for alarms.

  • Charts and visualizations: Combining data from data sources with different measuring intervals in the same chart may lead to less consistent visualizations or unexpected display behavior.

Recommendation

For the most consistent monitoring results, do one of the following:

  • Only use data sources supporting the same measuring interval.

  • Align all data sources to the largest common measuring interval. This means that for some of your sources, you set a measuring interval that is longer than what the source is capable of providing. The data sent will then be aggregated to the set interval.

Transmission interval

The transmission interval is the frequency at which data is transmitted continuously between the data source and the portal.

  • It is not entered during data source setup in the portal. You may enter it in the settings of your data source itself, but this does not affect the interval in the portal.

  • The portal calculates this interval based only on communication with the data source over the past 3 days.

Tip

To check the latest data transmission, see Verify data transmission to the portal's server.
