Simple configuration direct in the TIA Portal

The SIMATIC Energy Suite is an option package for STEP 7 and WinCC (TIA Portal) which integrates new editors into the engineering HMI of the TIA Portal. These editors can be used to create and configure energy measurement points (so-called 'energy objects') in a simple manner. In addition to various parameters which are available, the following steps are of central importance when configuring an energy object:

• Assignment of an energy data source
  The data source can be any tag from the data function of the PLC (power rating value, energy count value or pulse signal from e.g. tag table, data block etc.) or from one of the devices supported by the Energy Support Library (see "Design" Topic).
• Assignment of a calculation and archiving period
  Each energy object can be assigned an individual calculation and archiving period (1 min up to 24 h) for preprocessing the power rating and energy values relevant to billing. For example, energy suppliers bill electrical energy in 15-min periods and piped media (e.g. water) in 60-min periods.

Automatic program generation instead of complex programming

Following the completed configuration of all energy objects, the S7 energy program is automatically generated by the program generator of the Energy Suite. This energy program can be downloaded to the controller (S7-1500) immediately after the compilation, and commences at once with recording and preprocessing of the energy values.

Energy data recording and preprocessing is already carried out in the automation environment, close to the consumers

The recorded energy data is standardized and calculated according to the set archiving period, provided with a time stamp, and is ready for archiving. Archiving of the power rating and energy values relevant to billing can be made directly on the PLC-internal SIMATIC Memory Card or in a connected WinCC Professional archive.

Free choice of archive location

Archiving of the power rating and energy values relevant to billing can be made directly on the PLC-internal SIMATIC Memory Card or in a connected WinCC Professional archive.

• Archiving on SIMATIC Memory Card
  The energy data is directly saved on the CPU-internal SIMATIC Memory Card according to the respective archiving period. The data is always available there as a CSV file for direct downloading via the CPU's web server
• Archiving in WinCC Professional archive
  The energy data is saved in the archive of a connected WinCC Professional system according to the respective archiving period.
  Buffered communication
  To ensure high data quality, the energy data is buffered in the WinCC archive prior to transfer. The data is then still available in the WinCC archive without losses or errors even after a longer interruption in communication with the archive system (e.g. when restarting the PC or when there is a fault in the IT network).

Export tool for simple reading of energy data

The energy data in the archive of the WinCC Professional system can be directly exported from the archive database to an Excel file using the supplied export tool. Individual export templates can be created (free selection of measurement points and time periods) which subsequently need only be started by the user when desired (e.g. at the beginning of each month) without additional configuration.

Display and monitoring of the energy data

When generating the energy program, the power rating and energy data of the individual measurement points (energy objects) is made available in uniform S7 blocks with standardized data structures. In addition to the current and periodic energy values, this data also includes all relevant configuration data. Thanks to this central and uniform provision of data in the S7 CPU, it is very easy to implement additional real-time monitoring and evaluation (e.g. calculation of key statistics) in the control program as well as uniform visualization of the energy data and energy parameters on HMI and SCADA screens.
