4 1 Task 1.1 Overview 1 Task 1.1 Overview Introduction Rising costs for electricity are an important cost factor, especially for the energyintensive applications often used in the automation sector. This places more and more emphasis on the topics of energy efficiency and energy management in automation technology. The electrical operating data, such as the received power of the components of a plant shall be acquired, stored and analyzed. This enables determining energy pigs and the energy demand of a plant can be optimized. Overview of the automation task The figure below provides an overview of the automation task. Figure 1-1 PLC 1 Central station 3 Evaluation module 1. A PLC controls a number of electrical consumers. 2 Consumer 2. The electrical operating data is acquired and prepared by means of an evaluation module. 3. The data acquired in this way are transferred to a central station for further analysis. Entry ID: , V1.0, 06/2015 4

5 2 Solution 2.1 Overview 2 Solution 2.1 Overview Schematic layout In response to the requirements of energy management and energy efficiency, SIEMENS offers the measuring module ET 200SP AI Energy Meter ST as evaluation module for the distributed I/O system ET 200SP. Using the energy meter, electrical operating data, such as applied voltage, received current, reactive and active power etc. of the connected consumers, can be acquired and prepared for analysis. Note This application example is based on the configuration of energy meters. A comprehensive information collection is available in \6\. We recommend you familiarize yourself with these documents before continuing with the application example on hand. Knowledge of handling these components is assumed here. In order to keep the number of required hardware components as low as possible, an operator panel for the display is not used in this solution. Instead, the energy meter forwards the operating data to the controller. The controller replaces the operator panel by inserting the operating data into a set of HMTL pages stored in the integrated web server of the CPU. The operating data reaches the display via the dynamized web pages and can be viewed from any web browser with access rights. This makes the operating data also available for remote maintenance via the internet. For generating a group of HMTL pages that are used for dynamically displaying the data supplied by the energy meter via the web server of the CPU, SIEMENS provides the Energy Meter Web Configurator tool free of charge for download. The application on hand focuses on operating the Energy Meter Web Configurator. Setup and application of an ET 200SP distributed I/O and the ET 200SP AI Energy Meter ST is discussed in the further literature. (See also Links & Literature in Chapter 3.3, Driver block FB E2M_1500_AIEnergyMeter_DRV) The following figure displays the most important components of the solution: Entry ID: , V1.0, 06/2015 5

6 2 Solution 2.1 Overview Figure 2-1 S IM155-6PN HF with ET 200SP AI EnergyMeter ST Consumer PROFINET IE PC (for evaluation) PC/PG (for configuration) The web pages generated by means of the Energy Meter Web Configurator enable a quick and comfortable overview over the consumer behavior of the connected components with little configuration effort. Setup The setup mainly consists of a SIMATIC S PN/DP PLC as the central controller. The PLC is connected to an ET 200SP distributed I/O via PROFINET using an IM155-6PN HF interface module. Part of the ET 200SP are also three AI Energy Meter ST for measuring the electrical values of up to three consumers. 1 Furthermore, you need a PC on which the AI Energy Meter Webpage Energy Meter Web Configurator runs, as well as a PC with a web browser on which the consumption data can later be displayed. (Both PCs may be the same device.) Advantages The solution presented here offers you the following advantages: Application of the free of charge Energy Meter Web Configurator Fast and intuitive generation of an overview over the power consumption, based on the configuration of your plant Low configuration expense Uncomplicated access to data from each internet-capable PC Using a user-defined graphic (e.g. a plant layout) as background image Intuitive navigation through the configured plant for verifying individual components With the help of the overview, you can control the energy consumption of your plant and identify energy pigs and critical consumers Dynamic update of displayed data (cycle time approx. 500 ms) Flexible application and simple adaptation of the solution Suitable for a number of controllers (S7-1200/1500) 1 Further energy meter modules for the expansion of the plant can be integrated easily.

10 3 Mode of Operation 3.2 Blocks of the supplied TIA Portal project dynamization of the HTML pages. (See also the following section.) The PLC polls the operating data saved by the energy meters of the distributed I/O, and prepares them. Previously, the plant with its end consumers was depicted on a connected PC (4) using the Energy Meter Web Configurator. The result is a set of web pages which are downloaded to the controller. These web pages are dynamically updated along with the operating data downloaded by means of the E2M block and can be viewed from a connected PC via web browser (5). 3.2 Blocks of the supplied TIA Portal project The TIA Portal library supplied within the framework of this application example contains a number of blocks which ensure the interaction between the energy meter and the web pages generated by the Energy Meter Web Configurator. The following figure shows you an overview of library blocks integrated into a project. Figure 3-2 EMWebConf_Driver_Data_Array This DB collects the data of the energy meter to be evaluated and stores them intermediately. The DB consists of an array of 20 elements, of which one each is assigned to an energy meter. The element with the index 0 takes on a special role: In order to keep the communication load as low as possible, the data of each element with the current energy meter index is copied into the 0 th element, and only the 0 th element is forwarded to the web server. EMWebConf_Prepare_Data, EMWebConf_Prepare_Data_DB This function block and the respective data block control the conversion of the data read into the CPU by the energy meters, as well as the forwarding to the web blocks for visualization.
