4 1 Introduction 1 Introduction 1.1 Overview Energy efficiency plays an important role in today's world. Using the S7 energy efficiency monitor (S7 EE-monitor for short), you can record and analyze the consumption of the media used (compressed air, electrical energy or heating gas) by your machine with a SIMATIC controller. The S7 EE-monitor calculates the average power and actual value, the distribution of energy and the requirements of the media used per produced piece good for each machine state. This enables you to detect potential for savings and to improve processes. By saving resources, you can save money and protect the environment. This application example shows you how to set up the S7 energy efficiency monitor and display the evaluation on an HMI device. 1.2 Principle of operation The "EnS_EEm_Calc" block is responsible for recording and calculating staterelated energy data. The "EnS_EEm_Report" block uses the measured values to generate an efficiency report for detailed evaluation and documentation. The "EnS_EEm_ComEnMPRO" block establishes the connection to the central energy management system SIMATIC Energy Manager PRO and transmits the status-related energy counters cyclically (1min) Blocks The following blocks are provided in the SIMATIC Energy Suite V15 for recording energy efficiency: "EnS_EEm_Calc" "Ens_EEm_Report" The blocks are available in the TIA Portal under "Instructions:" Figure 1-1 Energy Efficiency Blocks Entry ID: , V2.0, 10/2018 4

5 1 Introduction Machine manufacturers can integrate this function into their machines to automate the generation of the energy and media requirements as an acceptance form in SIMATIC HMI and Excel. Note The blocks can be integrated preliminarily into the program without a license. "EnS_EEm_Calc" The block records the energy and media requirements for the energetic modes "off", "standby", "powering up", "operational" and "working". Functions: Record typical power consumption as reference values for the energetic states. Record energy and media requirements for each mode. Calculate energy performance indicators (EnPI). The operation as well as the individual functions of the "S7 EE-Monitor" are explained in chapter 5. Power ranges: The block calculates the energy requirement and average power of the respective mode as well as the total energy requirement for up to eight operating modes. A maximum of ten measuring points can be configured. The visualization on the "SIMATIC TP 900 Comfort Panel" is designed for up to four measuring points, but can be extended as required by copying the visualization elements. Note Additional information on the energetic states of a production machine and the energy performance indicators can be found in chapter 7. "EnS_EEm_Report" By request, the "EnS_EEm_Report" block creates a log file with the average power values as a CSV file. The file is saved on the SIMATIC memory card of the controller. You can use the "EnS_EEm_report.xlsx" (Figure 1-2) measurement log to evaluate the.csv file and create a measurement log that complies with the technical rules of VDMA Note To use the blocks, you need the following license. See chapter 1.3. Entry ID: , V2.0, 10/2018 5

10 2 Engineering PLC 2 Engineering PLC 2.1 Hardware setup (example) The example system consists of various devices that can output and store energy values. By using an AI Energy Meter 480V, it is possible to measure energy consumption through distributed I/Os. This application example makes use of the following process tags: Table 2-1 No. Process tag Medium 1. Electrical Energy (EM 480V) electrical (W) 2. Compressed Air air (m³) 3. CoolingWater liquid (m³) 4. SpeedAxis (e.g.: SINAMICS G120D) electrical (W) Figure 2-1 Example process tags CoolingWater ElectricalEnergy CompressedAir SpeedAxis In this example, the system has a total of 4 process tags. The measured data of the process tags 2-4 is provided in form of a data block. In this application example, the data is collected in the data block "EnS_EEm_OEM". The individual process tags are assigned random values for demonstration purposes. The consumption of used media should be evaluated and the energy efficiency displayed. A 9-inch "SIMATIC Comfort Panel" is used for the visualization. In a "SIMATIC S7 CPU 1512", the "S7 EE-Monitor" will collect the required data and transfer it to the SIMATIC Panel. Energy efficiency is displayed via the "S7 EE- Monitor" visualization. This chapter describes how you have to parameterize the controller in order to commission and configure the "S7 EE-monitor".

You can now copy the corresponding CSV file from the "SIMATIC memory card". This is required for the subsequent steps. 6.2 Saving the CSV file Requirement: A reference and load measurement has been already taken and energy data is available. Procedure 1. Click on "Test" in the main navigation of the tool. 2. Click the field button on the right side of the screen. 3. Click on the "Create.CSV report" function. Figure 6-3 The name of the CSV file consists of the configured machine name and the date. 4. Copy the CSV file from the "SIMATIC memory card" to your computer, e.g. via the web server of the controller: 5. To start the web server open a web browser and enter the IP address of your controller (e.g. in the address field. Entry ID: , V2.0, 10/

Save the generated CSV file. 6.3 Generating an energy log based on the Excel template Note The Excel template is tested for the Microsoft version Download the Excel template "EnergyReport" from the following page: 2. Open the Excel document. The document contains macros. These facilitate the import of the CSV file into the Excel document. The program code runs automatically and assumes the following tasks: In the csvdata spreadsheet: a. Delete the old data record. b. Insert the new data with the "AddQueryTables" function. c. Execute the function "Text in columns". d. Delete unnecessary spaces in the imported data ("Find & replace" function). 3. Click the "Select csv-file" button. Entry ID: , V2.0, 10/

41 6 Energy efficiency reports Figure In the dialog box, select the saved CSV file with the energy data and click the "Open" button. 5. The data is imported and is now available in the "csvdata" spreadsheet. 6. The log is automatically supplied with the saved data from the "csvdata" Excel spreadsheet. Note If you use the Excel template without macro function, you must perform the aforementioned functions yourself and add the data from the CSV file to the "csvdata" spreadsheet, starting from cell "A1". Result: The first spreadsheet shows the content of the data read. The table extends automatically depending on the imported data record. The report can now be printed or saved. 6.4 Notes on using the Excel template On the first spreadsheet, you should only make changes to the gray boxes. If you change other values from the log, they will not be updated any more. Figure 6-6 Text boxes that can be modified in Microsoft Excel. Note Do not delete any rows or columns from the "csvdata" spreadsheet because the Excel document might no longer function properly. Entry ID: , V2.0, 10/

42 7 Useful information 7 Useful information 7.1 Energy efficiency factor The EnPI (energy performance indicator) factor indicates the energy required to produce a particular product. Example: Tool creation Energy, in the form of water, gas and electricity, are required for production. An EnPI value can be calculated for each medium. Table 7-1 Medium Consumption Quantity EnPI Electricity [kwh] kwh kwh / unit Water [l] Gas m³ l l / unit 850 m³ m³ / unit The "S7-Energy Efficiency monitor" calculates and displays EnPI factors graphically so that the values can be used to estimate the required energy and evaluate the quality of production. By calculating a reference value for the EnPI factors, it is possible to measure the current EnPI factors from the reference values. Note The recalculation of the EnPI values is only performed when the piece count is changed. 7.2 Energetic states of a production machine: The VDMA technical rule defines the following energetic states for production machines. Off The machine is switched off Standby Machine is in a "Standby mode" for example. via PROFIenergy (SIOS entry ID ) Powering Up The energy needed by the machine to return to its ready state from Off/Standby. Operational Machinery is ready for operation Working Machine is producing Entry ID: , V2.0, 10/

43 7 Useful information The technical rule also specifies which energy and media values have to be recorded and what has to be observed during the measurements. 7.3 Energy efficiency analysis in the Energy Manager PRO The Energy Manager Pro is also provided for the analysis of energy data. The Energy Manager Pro offers extensive functions: Analysis of the individual machines machine comparisons line cost center reporting For comparison the advantages of the S7 EE monitor: local visualization acceptance report data preparation Display of the data in the machine dashboard The raw data and energy key figures can be individually displayed in the Energy Manager PRO in reports or dashboards.
