7 3 Basics 3 Basics Measuring points Microsoft Excel 2010 The Excel macro evaluates files of the ".*csv" type that include up to 200 measuring points. In Microsoft Excel 64 bit the number of rows per spreadsheet is limited to 1,048,576. The Excel macro evaluates Excel files with up to 1 million data records per month. The macro is optimized for Microsoft Excel If you are using Microsoft Excel 2013 or higher, please switch off Animations in Microsoft Office, if possible. This increases the general performance of your Microsoft Office. Size of the Excel file Use files up to a size of 180 MB in order to prevent loss of data. Evaluation The Excel macro evaluates precisely one measuring point for one year. This measuring point and the year can be selected in the Excel sheet Overview after the import of the data records. The macro evaluates data logs with the suffixes "*_energy" and "*_power". Performance The speed of the macro depends on the number of data records in the file to be evaluated and of the hardware on which the Excel macro is running. Entry ID: , V1.0, 03/2017 7

17 5 Mode of Operation of the VBA Macro 5.1 Structure of the macro This application example consists of a total of 28 Excel sheets. The Excel sheets are required for the following functions: Operation and configuration of the macro Data management Representation of the diagrams Operation You operate the macro in Microsoft Excel via the Excel sheets Overview and Dashboard. In the Excel sheet Overview you import the data records and evaluate them. The Excel sheet Dashboard offers you a compact display of diagrams that are created by the macro. In the monthly Excel sheets ( Jan, Feb etc.) you can access individual diagrams after the evaluation, in addition to the "Dashboard". In Chapter 4 the operation of the Excel macro is explained. Data management The macro saves all data from the imported Excel file in the Excel sheet DataImport. The further evaluation of the data according to selected measuring points and selected year is done in the data Excel sheets *Data. The placeholder * stands for the abbreviation of the month, for example, JanData. To have a better overview, these Excel sheets are hidden. Diagrams For each month, three different diagrams are created. Table 5-1 Diagram Display Energy Value diagram Display of the energy consumption for the month. Entry ID: , V1.0, 03/

The diagrams created are stored in the Excel sheets Jan, Feb, etc.

18 5 Mode of Operation of the VBA Macro Diagram Peak Power diagram Display Display of the power peaks for the month. Detail view diagram Detailed view with selectable period. The diagrams created are stored in the Excel sheets Jan, Feb, etc.. As soon as the data is available for a month, the Excel sheet is automatically displayed after the evaluation. The macro furthermore creates an annual overview. You can find it in the displayed Year Excel sheet. Entry ID: , V1.0, 03/

19 5 Mode of Operation of the VBA Macro 5.2 Structure of the program code The Excel macro was written in the Visual Basic for Applications (VBA) programming language. For a better overview the code is divided in modules. Forms are used for dialogs, they are called UserForms. Note This chapter explains you the structure of the program codes that is behind the Excel macro. The VBA editor can be opened with the key combination <Alt> + <F11> when Microsoft Excel is open. Forms Modules The macro works with the following UserForms: UserFormProgress (progress display) UserFormPDF (storage dialog) The program code of the Excel macro is divided in the following seven modules: Modul00_Functions_Consts In this module, global constants and tags as well as generally valid functions are stored. Modul01_Import In this module, the data records for the Excel file to be imported are stored separately in the Excel sheet DataImport. Afterwards, date and time as well as spaces and quotation marks are removed separately in the data records. Modul02_Evaluation This module includes the following functions for the evaluation of the data records: Filtering data records in Excel sheet DataImport according to year and measuring point. Dividing data records in data Excel sheets by month ( JanData,...). Updating diagrams. Hiding diagrams without displayable content. Modul03_Analyse Module 3 analyzes the data records. The following information is displayed and then output: Time stamp of first data record Time stamp of the last data record Archiving cycle Number of data records Modul04_Detailview The functions in this module refer to the Detail view-diagrams. The following functions are stored in this module: Entry ID: , V1.0, 03/

20 5 Mode of Operation of the VBA Macro Filling of the drop-down lists with the available date specifications of the data records Resetting the drop-down lists. Accepting the selection of the drop-down lists for the filter settings of the diagram Modul05_Overview The functions in module 5 relate to the Excel sheet Overview. The data records are searched for measuring points and years included and then displayed in the list fields on the Excel sheet Overview. Modul06_Dashboard The functions in module 6 relate to the Excel sheet Dashboard. Copy the original diagram from the monthly Excel sheets Jan, Feb,... and add it in the dashboard. 5.3 Core functionalities Saving as PDF file You find the VBA code to save the diagrams as PDF file in the VBA editor in the form UserFormPDF. It consist of three click events for the check box All and the buttons [ ] and Save. Call The UserForm is opened by clicking the button Save as PDF on the Excel sheet Overview. Mode of operation Select the objects to be printed via the checkboxes. By clicking on the Save button the sub-function Button_Save_Click() evaluates the check boxes. The diagrams are copied in a new, temporary Excel sheet. This is printed with the default Export function as PDF file and saved in the path specified by you. Then the temporarily created Excel sheet is deleted Importing data records The Import function imports the data records of a.xls file into the Excel workbook. Call Click the Load Data button in the Excel sheet Overview in order to start the Import function. Entry ID: , V1.0, 03/

21 5 Mode of Operation of the VBA Macro Structure By clicking the LoadButton button in the overview table the LoadButton_Click() function is called. This function calls the following sub-functions one after each other: Table 5-2 No. Name Function 1 deleteall Corrects the following Excel sheets and resets the internal tags: DataImport and Month Data ( JanData, FebData, ) Overview Excel sheet Dashboard Excel sheet 2 csvimport Separates the data records of the Excel file to be imported and stores it in the Excel sheet DataImport.

Call Structure Click the Evaluation button in the Excel sheet Overview in order to start the Evaluation function. In the click event EvaluationButton_Click() of the Overview table the following core functions are called one after another: Table 5-4 No. Name Function 1 filterdata Filters the Excel sheet DataImport according to selected measuring point and year with the auto filter function. 2 ClearMonthData Deletes the exiting content from the Excel sheets Month Data (for example, JanData, FebData etc.) and resets the filter in these Excel sheet. 3 Evaluation Separates the data records from the Excel sheet DataImport in the individual months and saves them in the respective Excel sheet (for example, JanData ). 4 hideinactivesheets Hides all months that don t contain a data record. 5 refreshpivottables Updates the data tables of the workbook. 6 configuratecharts Creates the formatting of the diagrams for all diagrams in the workbook. 7 findinterval Determines the update interval and finds gaps in the data records. After the evaluation, the information determined is shown in a notification window. Entry ID: , V1.0, 03/

23 6 Further Notes, Tips & Tricks, etc. 6 Further Notes, Tips & Tricks, etc. Notes For reasons of performance the AutoSave Excel function is disabled for this macro. If required, save the workbook manually. If you evaluate large files and save them afterwards, this takes more time during saving and loading of the Excel workbook. For large data volumes it may happen that Excel no longer responds during the execution of the macro. In this case, wait until the macro is finished. Then you can operate Excel again.
