Software system PROMOTIC METERING is a multi-purpose configurable application that provides automated reading and processing of data from energy meters (Wärme, Wasser, Gas, Elektrizität usw.) of various brands. The communication with meters uses standard protocols (M-BUS, Modbus, M-BUS Ethernet usw...)

Anzahl meters connected to the system is not limited. Authorized personnel can add meters and edit their parameters (meter type, addresses, usw.). Overview graphic cścreens indicate the staus of all meters and it is also possible to see details of selected meter.

The system executes archiving and evaluation of consumption of energy in defined time period (day, Monat, jahr, other time period). The system can also Export the data into MS Excel files or into enterprise databases (SAP, Chastia, usw.) - as source data for invoicing.


System architecture

The system architecture is built on Klient-Server platform

A) The communication, data and Web server (with visualization) provides:

- data reading from energy meters by standard protocols: M-BUS, Modbus, usw...
- archiving of measured values into standard database
- visualization of technology für Web clients by dynamic HTML pages

B) Visualization Web clients allow inspectional visualization of all data gathered from meters and provide output reports and summary overviews of energy consumption in defined time period.

- Visualization station works as so-called a "thin Web client" (using only Web a browser, z.B. Chrome, Firefox, Edge, InternetExplorer usw..). The main advantage of such solution is the fact that no special software needs to be installed on the client stations, only a Web browser is needed.
- The client station can therefore be represented by a classic PC or by a tablet, smartphone usw. This approach also makes the clients platform independent (Windows, Android, iOS, Linux usw.). For this functionality there must obviously be a working TCP/IP connectivity between the server and the visualization stations.

Kommunikation with energy meters

The communication with energy meters usually uses M-BUS oder M-BUS Ethernet protocol. Meter addresses can be entered either as direct (meter adresse on M-BUS link) oder as so-called a secondary address (usually represented by the meter serial number). The latter approach is handy especially if a failed meter is replaced by another. The reading period (frequency, time) can be defined in the configuration file.
Examples of data gathered from meters:
- total energy (in GJ) (total meter counter value)
- total volume (in cubic meters) (total meter counter value)
- current output (kW/hour), current flow [m3/hour)
- meter type, measured medium type, secondary adresse (serial number)
- Temperatur in, Temperatur out, Temperatur difference
- counter status (impulse inputs, z.B. from water meter), error messages
Reading period (time) can be defined globally for all groups or independently for each group. The reading time can be entered as:
- a specific time for each day in a month
- daily the same time
- every hour the same minute


The status of all meters is indicated on the overview visualization screen and it is also possible to display detailed information of each selected meter.
- The topological overview (map) of heat meters with color indication of meter status (communication OK, malfunction, disconnected, usw.).
- Overview screen with table view of meter status, counters, last read time and other data read from meters. Possibility to display real time data from selected meter - the data is read from meter.
- Graphic overview measured values time progression (trends): daily heat consumption, volume, temperature siehe
- Overview screens with summarized reports (daily, monthly consumption)
- Alarm system - detection and indication of communication malfunction

System konfiguration

Anzahl meters connected to the system is not limited (249 meters can be defined in one group, number of groups is not limited). Authorized personnel can add meters into the sytem und edit parameters (meter type, name of measured locality, meter adresse usw.). Once the application is launched all the parameters are read from configuration files, then the system automatically establishes connection with defined meters and data reading. The system also provides initial identification of meters that are connected in each group (so-called initialization mode). Meter parameters that are read are then saved into initialization files. Additional parameters can be then added by system administrator:
- meter type
- name of measured locality
- device serial number
- meter adresse (on M-BUS link)
- unit (kW,…), multiplication Konstante for recalculation, usw.
User permissions:
- The system can define 2 types of users:
- administrator
- user
- On the PC station of the Server type, it is possible to execute all operations corresponding to the permissions level of user. The Web interface (PC Web client) allows to execute complete processing of protocols and overviewing database data. Modification of data in configuration database tables and system parametrization can be done only on PC of the Server type.
- Access to administrator functions of the system is protected by access rights.

Archiving and evaluation of measured data

The system archives measured data into standard database format (z.B. Access, Dbase, MS SQL - as needed). The system also provides evaluation of consumption of energy in defined time period (day, Monat, jahr, user defined range). Consumption evaluation is done for each meter individually or for groups of meters as group summary:
- defined groups of meters (z.B. for boiler room, heating circle, usw.)
- defined consumers, customers
Assigning of meters to summary group is defined in configuration file that is loaded by the Applikation while being launched.

Data exports

The system can also provide data exports into files MS Excel that can be used as source data for invoicing. Individual daily consumption data is saved in the file. The format of exported data can be adapted as needed.


The application for meter data reading has been created in SCADA software PROMOTIC. This software tool can be used to design both simple and complex monitoring systems that can be interconnected with enterprise IS, databases, Internet, usw. In the PROMOTIC system there are bult-in standard software interfaces for data exchange between technological processes and other devices or systems:
- database access using ODBC, DAO, SQL
- connectivity TCP/IP, HTTP, XML, OPC, DDE, ActiveX
- large library of communication drivers
The software can be used in a wide variety of technologies. It provides real time overviews indicating status of all connected meters, executes evaluation and archiving of energy consumption in defined time period. It is a multi-purpose and highly configurable system that can read data from various meters. It can be extended by adding meters without the need to modify the application source code. The user can also Export measured data into MS Excel files. The system can also be extended in order to read consumption of additional media: Elektrizität, Gas, usw.. The system is open for interconnection with other systems e.g. the enterprise IS where the data can be transmitted.
