Python script: Launch Codesys, Execute Script, Exit Codesys

2026-02-12T11:04:55.182000Z

For whoever finds this old thread.
Instead of System.exit(0), use system.exit(0) without capital 'S', this worked for me.

I use these imports
from future import print_function
import sys
import os

Hello

I am looking for the same thing, so i don't have an answer, but in your case you could possibly use the --noUI flag when running codesys, if you don't care about showing what's happening.

Hi,

sorry I can´t help you with your issue, but I hope you can give me a hint on getting GUID for other objects than POUs.

Your code states "Guid("6f9dac99-8de1-4efc-8465-68ac443b7d08")". We can I find the GUID / ObjectIds`?

I wasn´t able to get details about the GUID of DataTypes (STRUCT/ENUM,..)m, Functions (FUN), GLOBALS and TYPES.
I want to create markdown of all available project elements.

Thanks for your help

Dear all:
Question about scripting: I am creating a .NET program that is supposed to Open codesys, open template project, export a bunch of pou, then exit codesys.

Launch works, Open project works, Export works, But how do i tell codesys to close itself? I can tell windows to terminate codesys, but i would prefer to do it properly.

from __future__ import print_function
import sys
import System
proj = projects.primary
# We're interested in POU nodes:
POUGuid = Guid("6f9dac99-8de1-4efc-8465-68ac443b7d08")
# We collect all POU nodes in that list.
pous = []
# From the parent node on, we recursively add POU nodes:
def CollectPous(node):
    if node.type == POUGuid:
        pous.append(node)
    else:
        for child in node.get_children():
            CollectPous(child)
# Now we collect all the leaf nodes.
for node in proj.get_children():
    CollectPous(node)
# We print everything just to know what's going on.
for i in pous:
    print("found: ", i.type, i.guid, i.get_name())
# And now we export the files.
for candidate in pous:
    # We create a list of objects to export:
    # The object itsself
    objects = [candidate]

    # And sub-objects (POUs can have actions, properties, ...)
    objects.extend(candidate.get_children())

    # And the parent folders.
    parent = candidate.parent
    while ((not parent.is_root) and parent.is_folder):
        objects.append(parent)
        parent = parent.parent

    # Create an unique file name:
    if len(sys.argv) == 1:
        filename = "parent\\%s.export" % (candidate.get_name())
    else:
        filename = "%s\\%s.export" % (sys.argv[1],candidate.get_name())

    # print some user information
    print("exporting ", len(objects), " objects to: ", filename)

    # and actually export the project.
    proj.export_xml(objects, filename)

proj.close()
print ("script finished.")
System.exit(0) // Dont work

.NET:

        public static void Export(string path,string proj)
        {
            if (checkSettings())
            {
                var p = new System.Diagnostics.Process();
                p.StartInfo.FileName = Properties.Settings.Default.CSVersion +"\\CODESYS\\Common\\CODESYS.exe";
                p.StartInfo.Arguments =
                    " --Profile="  + qoute(Properties.Settings.Default.CSProfile) + 
                    " --culture=en" +
                    " --project="  + qoute(path + "\\" + proj)  +
                    " --runscript=" + Properties.Settings.Default.LastOpenProjectPath + "\\INPUT_DATA\\SCRIPT\\Export.py" +
                    " --scriptargs:" + qoute(path)


                    ;
                p.StartInfo.RedirectStandardOutput = true;
                p.StartInfo.UseShellExecute = false;
                p.StartInfo.CreateNoWindow = false;
                p.Start();
                p.StandardOutput.ReadToEnd();
                p.CloseMainWindow();
                p.Close();
            }

        }
