Post by kbazzett on "Sequent Microsystems" industrial automation hat raspberry pi ^{CODESYS Forge talk (Post)}
Here is a complete list of the Sequent Microsystems Pi hats that work in Codesys. https://github.com/SequentMicrosystems/SM_CODESYS/tree/main/ "For easy install download the .package file and open it on your computer, Codesys installer will know what to do with it." <- This. The Multi I/O Hat fit my needs because of the Analog I/O 4-20ma and RTD. I used a Raspberry Pi 5 and 64b install. The example project is also worth the download. With the sample project open, right click on the Raspberry Pi device and update to whatever you are using (SL, MC, 64b). Enable I2C on the PI. You can jumper the hats Analog Outputs to Inputs and see it function on the Web Visualization. Very Cool! I spent quite a bit of time trying to find this solution so hopefully this update helps others. Here is the video link on how to setup a Raspberry PI as a Codesys PLC https://youtu.be/RPoPscbo3Kc?si=Th4-n-mQ6g5fdHj8

Post by jst69 on Python script: Launch Codesys, Execute Script, Exit Codesys ^{CODESYS Forge talk (Post)}
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(); } }

use the PLClogic directory to read / write files. /var/opt/codesys/PlcLogic this is due security reasons forced to use.

Hi, the subsequent interpreter should report an error? The reader is just reading the file without checking the syntax.
