Buildings.Utilities.IO.Files.Examples.CSVReader

Reader for csv files generated by CSVWriter

Buildings.Utilities.IO.Files.Examples.CSVReader

Information

This model demonstrates how a CombiTimeTable can be used to read a text file that contains a table. The text file is stored in Buildings//Resources/Data/Utilities/IO/Files/Examples/CSVReader/Data.txt. It has the format of a file that can be generated by Buildings.Utilities.IO.Files.Examples.CSVWriter.

Extends from Buildings.Utilities.IO.Files.Examples.BaseClasses.PartialCSV (Base model for CSV reader and writer example).

Modelica definition

model CSVReader "Reader for csv files generated by CSVWriter" extends Buildings.Utilities.IO.Files.Examples.BaseClasses.PartialCSV; Modelica.Blocks.Sources.CombiTimeTable combiTimeTable( tableOnFile=true, fileName=Modelica.Utilities.Files.loadResource("modelica://Buildings//Resources/Data/Utilities/IO/Files/Examples/CSVReader/Data.txt"), columns={2,3}, tableName="tab") "Reader for test.csv"; end CSVReader;

Buildings.Utilities.IO.Files.Examples.CSVWriter

Example of csv writer use

Buildings.Utilities.IO.Files.Examples.CSVWriter

Information

This model demonstrates the use of the csv file writer.

Extends from Buildings.Utilities.IO.Files.Examples.BaseClasses.PartialCSV (Base model for CSV reader and writer example).

Modelica definition

model CSVWriter "Example of csv writer use" extends Buildings.Utilities.IO.Files.Examples.BaseClasses.PartialCSV; CombiTimeTableWriter combiTimeTableWriter( nin=2, samplePeriod=0.3, fileName="test.csv", significantDigits=10) "Model that writes two inputs to csv file in a format that can be read by a combiTimeTable"; Buildings.Utilities.IO.Files.CSVWriter csvWriter( writeHeader=false, nin=2, samplePeriod=0.3) "Duplicate to test for conflicts when instantiating multiple file writers"; equation connect(cos.y, combiTimeTableWriter.u[1]); connect(step.y, combiTimeTableWriter.u[2]); connect(csvWriter.u[1], cos.y); connect(csvWriter.u[2], step.y); end CSVWriter;

Buildings.Utilities.IO.Files.Examples.JSONWriter

Example use of the JSON writer

Buildings.Utilities.IO.Files.Examples.JSONWriter

Information

This model generates four json files, using a single or multiple inputs and at different points in time.

Extends from Modelica.Icons.Example (Icon for runnable examples).
