Overview

This example imports a device in PLCOpenXML from Subversion via command line svn client. It can be started from the EcoStruxure Machine Expert user interface or from the command line.

# Script Example DeviceImportFromSvn.py

# Imports a Device in PLCOpenXML from Subversion via command line svn client
import os
 
# Some variable definitions
svn_executable = r"C:\Program Files\TortoiseSVN\bin\svn.exe"
project_file = r"C:\Python\test.project"
 
# !!! Important: File must be under version control !!!
export_file = r"C:\Python\SVN\MyController.xml"
 
# Clean up any open project:
if projects.primary:
    projects.primary.close()
 
# Fetch the PLCOpenXML data from subversion
# The with construct automatically closes the open pipe for us.
with os.popen('"' + svn_executable + '" cat ' + export_file, "r") as pipe:
    xmldata = pipe.read()
 
# Create a new project
project_reference = projects.create(project_file)
 
# Create the import reporter

# Import the data into the project
project_reference.import_xml(reporter, xmldata)
 
# And finally save
