Calculation of energy from gas volume (up to version 5.2.0)

Calculates energy in kWh from the gas volume in m³, the defined condition factor and the specified gross calorific value, then writes the value to the database as the OBIS identifier “Gas, final energy value, P+” (007-020:099.033.017*255). The calculation can only be performed for the medium “Gas” and the OBIS identifiers “Natural gas, load profile, standard cubic metres, T0” (007-001:129.130.000*255) or “Natural gas, load profile, operating cubic metres, T0” (007-001:128.130.000*255).

Parameters

Name/Designation/Title

A meaningful text entry. The designation is used for identification and search purposes and can be changed at any time.

Gross calorific value

Number – Parameter for gas quality that specifies how much energy (H-gas or L-gas) is contained in one cubic metre.

From version 5.2.1 onwards, this parameter is intended to be used as a fallback value if it is not available in OBIS-coded form.

Condition factor

Number – Factor based on the average temperature and air pressure at the location for converting the volume to standard conditions (0 °C, 1013 mbar).

From version 5.2.1 onwards, this parameter is intended to be used as a fallback value if it is not available in OBIS-coded form.

Time span

Defines how the time span of the action is determined.

  • Latest: The time elapsed between the last record and the time of execution.
  • Complete: The entire time span, starting from the timestamp of the first record.
  • Number of days: Full days in the past, counting from the time of execution.
  • Time range: Specify the start and end times precisely.

Completion trigger

Trigger – Specifies the trigger that is executed once the workflow has finished.
