Post by carl25 on Confused about stepper spec & tips on pwm-step/dir ^{CODESYS Forge talk (Post)}
Hello! I have asked the few I know who have knowledge of this and now turn to this one inexhaustible source of knowledge aka. the electronics forum. I was going to buy stepper motors yesterday but got so confused about the spec that I need to get an answer to this first. 2 different stepper motors, quite close in size but with very different spec. https://www.oyostepper.de/goods-40-Nema-17-Schrittmotor-Bipolar-12V-18-Grad-40Ncm-04A-12-Volt-4-Dr%C3%A4hte-Hybrid-Schrittmotor.html https://www.oyostepper.de/goods-38-Nema-17-Schrittmotor-Bipolar-18-deg-22Ncm-133A-28V-4-Dr%C3%A4hte-Hybrid-Schrittmotor.html Both Nema17 but the first 1.33A and 22Ncm and the second only 0.4A but almost double the torque. I can see that the resistance is very much higher on the latter but what's the catch? Double the torque to 1/3 the current sounds a little too good to be true so what am I missing?

Post by egau on Enable and Disable Project IO programmatically ^{CODESYS Forge talk (Post)}
Hi @eschwellinger, I tried this with Modbus COM slaves. I was able to disable them (slave becomes greyed out in the device tree), but the DED.Reconfigure "eError" output shows "NOT_SUPPORTED". After this, when I tried to re-enable the slave, it did not work (device stayed greyed out in the device tree), and the DED.Reconfigure "eError" output also showed "NOT_SUPPORTED". Is there something to do about this, or the device just doesn't support reconfiguration? P.S: I tried this running locally on my computer (not in simulation mode). So of course I was not physically connected to the devices. I have two similar projects, but one of them doesn't have the Modbus_COM devices. I know I can "Exclude from build" the devices for that project, but I would really prefer not to do this if possible. I would prefer to dynamically toggle a configuration variable that would enable or disable the slaves.

Hi, I have problem with connecting Wago PLC WAGO 750-8212/0025-0002 configured as OPC UA client to Kepware OPC UA Server. I am using Codesys 3.5.19.70. What I did so far. To the Codesys project I added object Data Source Manager and configured connection OPC UA like below: pic 1 Then I can browse the OPC server tags in “Variables” tab after prior trust on the server side of the client certificate created in the “Communication” tab: pic 2 Additionally second certificate has been created in Codesys for runtime process in “Security screen” as well as the server certificate was approved here: pic 3 But when I compiled project, downloaded it to PLC and go to RUN I can’t read selected in “Variables” tab, OPC Server tags. I am getting such error (ID: 7001): pic 4 All two PLC certificates has been trusted in OPC server (Kepware) side: pic 5 and Kepware server configuration look like this: pic 6 I can easily connect using third party OPC UA client UaExpert to Kepware server without problem. In attachment I added also log from Kepware OPC UA server. pic # - this specifies the number of a concrete graphic from one of the collective in attachment

Post by kuegerls on Programmatically clearing or syncing Data Source Manager cache? ^{CODESYS Forge talk (Post)}
Hi everyone, is there a way to programmatically clear the cache of the Data Source Manager in CODESYS so that variable values are re-synchronized from the OPC UA server (Symbol Configuration with OPCUA features)? Alternatively, is it possible to trigger a manual synchronization of data source variables from within the application code at runtime? Here’s the situation: A variable is first written by the OPC UA client to the server in one state of a state machine and changes to another state – so the initial communication works. Later, the server changes the variable value, but the client does not receive or reflect the updated value, unless the variable is actively written again. I’m looking for a way to force the client (data source manager) to re-read or refresh the variable state from the server, possibly by clearing the internal cache or triggering a sync. Any ideas or suggestions would be greatly appreciated! Thanks!

Post by shaunvdm on Canbus Slave SDO Read from Object ^{CODESYS Forge talk (Post)}
Busy testing a solution to use Canbus Slave to replace a physical device and convert to Ethercat device but keep the Canbus Master in place. Master needs to Read SDO object 5FA2. In the Master PLC if i send the SDO with 8 bytes in message IE: 60B 40 A2 5F 00 00 00 00 00 i get my expected 58B 43 A2 5F 00 00 68 36 02 containing data back. Problem is if we issue a 4 byte command can send 60B 40 A2 5F. Surely the canbus slave should respond with a 58B 43 A2 5F 00 00 68 36 02 but it comes back as 80 A2 5F 00 00 00 00 08 - meaning this OBJECT does not exist. Is there a setting in the canbus slave driver for Canbus to allow the 4 byte command to read the SDO OBJECTS ?

Post by astutoski on No Motion with SM3_RaspiStepper (GPIO 23/24 Show No Pulses) ^{CODESYS Forge talk (Post)}
Hi everyone, I’m completely new to CODESYS and have been teaching myself. And i Want to control an Axis using SM3RaspiStepper. Following the example on the RaspiStepper home page, I set up an axis through a POU and tied the SMC_StartupDrive (Visu) template to my axis instance (sud). Unfortunately, the motor never moves and I don’t see any pulses on the PULSE pin (GPIO 23). Hardware -Raspberry Pi 4 B -Nema 17 stepper motor -A4988 stepper driver (EN pin permanently tied to GND) Software / Runtime -CODESYS 3.5 SP21 Patch 1 – Raspberry Pi runtime (demo) -SoftMotion in demo mode -Package: SM3_RaspiStepper 0.0.0.6 Axis parameters: Pulse pin GPIO 23 Direction pin GPIO 24 Enable pin 0 (unused) Disable pin 0 (unused) Whether I start the axis from the visualization template or through Online Config Mode, the motor never spins. In Online Config Mode I press Power → the state changes from Standstill to Discrete_Motion, but the motor shaft is still locked and no step pulses appear on GPIO 23 (checked with a scope). I can provide screenshots of the Visualization, PLC logs, or wiring pictures if that helps. Any ideas on what I might be missing? Happy to provide screenshots, project files, or scope captures if that helps. Thanks in advance!

Post by dominggus on when going online, stuck on "Syncing file "visuelemsdatetime.tl_datetime.txt" ^{CODESYS Forge talk (Post)}
Hi, We are currently using a Raspberry Pi 4 CM4 module in a EdgeBox RPI 200 - Industrial Edge Controller running the latest CODESYS Runtime Package 4.11.0.0. On the PC (actually an Intel Macbook Pro running Windows 10 in Parallels) we run CODESYS V3.5.19.50. Yesterday end of day when I was about to logoff and head home, I wanted to send the latest build to the Raspberry I clicked the Login button to compile a new version and then sync the application and all the files, it get's stuck on the last file to sync (see attached screenshot). This takes eternally, although sometimes, when I use my SFTP client (Cyberduck) and go into the raspberry and refresh the directory /var/opt/codesys/PlcLogic/visu/, or when I open the actual file visuelemsdatetime.tl_datetime.txt, it gets un-stuck (forcing a refresh, which might fix the syncing issue) and CODESYS continues and I can click the Start button to start the application. But this SFTP force refresh trick does not always help either... What could be the issue here? network connectivity? Can someone please help me out?

Post by salvadegianluca on How to use TON inside an FB that is instanced within a Visu page ^{CODESYS Forge talk (Post)}
Hi everyone; I'm building a project in which the drag of the mouse over some controls (or the click event) changes the background color of the control items; this change of color is made with an FB that assignes a color code to the background with MUX command based on the value of an enumerator, this part is perfectly working but, when I'm using a touchpanel instead of a web visu (controlled by a mouse) I get into some issues as it seems that the touch operations are not triggering the MouseEnter and MouseLeave properties as it's done with the mouse.... For this reason I'm trying to add a TON to my FB and, if the enum that changes color remains at the same state for more then 3s I'm automatically resetting it to it's "0" so the item gets back the not selected color. Anyhow it looks like the TON function from library is not working in these FB that are instanced in the various visualizations, as instead they do if I create some instances within the POUS. Anyone has ideas of how to make them work?

Post by timvh on License problem gateway ^{CODESYS Forge talk (Post)}
What we are trying to explain is that, yes CODESYS creates the software, but Epis decides how they implement it on their hardware, which runtime version they use and they decide which functionality they support. So it is always a combination of the two. What CODESYS provides is a runtime with options for e.g. visualization or softmotion. Epis could add this softmotion license as default to their controller, but if they don't then CODESYS provides another option with a single license in a "Wibu CodeMeter" container. Eventhough the feature exists, Epis has to add this "CodeMeter" software on their controller to be able to access the licenses in the container. We don't know if they did this. Then finally it depends on what type of runtime is on this controller and which license Epis is using. So if they have an OEM license (not an application based license), then most likely you will need the Softmotion license (not a number of axis). See https://store.codesys.com/en/codesys-softmotion-sl-bundle.html. But to be sure if this is supported by the Epis controller, you must ask Epis.

Post by pernockham on Gateway in China - "Gateway not connected" ^{CODESYS Forge talk (Post)}
Some new test. Now I cannot connect from Automation server to my gateway in any way also from my office setup with my unit directly connected to my router by dhcp. I can use the IDE and the tool "Connect Edge Gateway" and successfully connect to my server/link to my Automation server account. However no PLC will respond from Automation server "Network scan". I guess the traffic should be initiated by the gateway towards automation server? Any tips on how I can diagnose my problem? Ports to be opened etc? Thing is that this has been working previously but not now (base system has been updated from debian 12 to debian 13, but I dont know at which point it has stopped working). Setup as before. A "Codesys Control for Linux SL" running on a debian 13 installation. Any help/tips appreciated! Per Update. Found the error. Had a wrong gateway-setting. Which meant the PLC could not reach internet. Checked by "ping google.com" from the PLC.

Post by yannickasselin on CloseTargetVisu ^{CODESYS Forge talk (Post)}
To shutdown the TargetVisu: Add the VisuElemBase library to your project then call VisuElemBase.Visu_PRG.RemoveAllTargetVisuClients(); Exemple: PROGRAM PLC_PRG VAR xShutdownTargetVisu: BOOL; END_VAR ---------------------------------- IF xShutdownTargetVisu THEN xShutdownTargetVisu := FALSE; VisuElemBase.Visu_PRG.RemoveAllTargetVisuClients(); END_IF I tried calling RemoveAllTargetVisuClients() directly from a button mouse click event but it makes the Visu crash. So better using the code above and just set xShutdownTargetVisu to TRUE from the button. Works fine for me. To start the TargetVisu: From a cmd prompt. This will start the TargetVisu C:\Program Files\CODESYS\CODESYS Control RTE3>VisualClientController.exe --application=Application --flags=1 You can then place a .bat file on the desktop and put this inside: CD "C:\Program Files\CODESYS\CODESYS Control RTE3" VisualClientController.exe --application=Application --flags=1 exit Double clicking the .bat file will start the TargetVisu. You may need to replace the Application name by your own application name. Good to know: In the cmd above, if you replace --flags=1 by --flags=2, it will shutdown the TargetVisu.

Post by dandyk on Dynamic Images ^{CODESYS Forge talk (Post)}
Hello, I have very similar problem, but it seems that your solution does not work for me. I am using TwinCAT XAE Shell v3.1.4024.55 and TwinCAT Runtime. Sorry for writing here on codesys forge, but since I found the only relevant topic here and since TwinCAT is almost the same with CODESYS in many applications, I chose to write here. I simply need to dynamically update image in visualization based on camera trigger (I am doing a machine vision application). Camera triggers an image, my program processes it (applies thresholding, draws contours etc...) and saves the processed image in the runtime location (the same one you were mentioning). This was done successfully. I need to make it work at runtime, while the program is executing and I need to refresh the image in the visualization each time camera triggers a new image and program processes it. When I create image element in the visualization and define the bitmap ID variable as STRING which contains the image ID defined in the image pool, then it displays the image in the image pool, but does not work at runtime, while the program is executing. I also used the Bitmap Version. I declared it in Global variable list as integer with initial value of 0 and wrote the variable in the bitmap version in the image element in visualization. Each time new image is saved to the runtime location, I wrote a program to increment Bitmap Version by 1. It increments and the image does not update in the visualization, unfortunately. I think that bitmap version is working correctly and deletes the cached image as it is supposed to, but the Image Pool does not update the image ID with the new image... the path to the image is always the same... only the actual image changes with the same file name. Image Pool is not dynamic and cannot refresh the image in the path to the actual one at runtime. How can I refresh the image ID in the image pool at runtime? Bitmap version only deletes cached image and reloads the image from the image ID, but the image ID has the same image, because image pool won't update at runtime. Do you know any solution to this problem?

Reicht es im Codesys Projektbaum mit "Gerät aktualisieren" auf den Wago Controller zu wechseln? Es wird dann statt dem "Pfc200Bus"ein leerer K-Bus und ein leerer Com-Port angezeigt. Müssen die einzelnen Module dann darunter neu angelegt und alle E/A Variablen manuell neu eingetragen werden? Das exportieren und danach wieder importieren funktioniert nicht, weil die Namen bzw. Adressen unterschiedlich sind. Ist das so richtig? Kann der Block "Modbus_COM_Port - Modbus_Master_COM_Port - Modbus_Slave" so bleiben wie bisher oder muss das auch unter dem neuen COM-Port neu angelegt werden? Für ein paar Hinweise wäre ich dankbar. Schöne Grüße, annD

Ich hab's hinbekommen: Nach dem Controller Update hab ich ein neues Projekt gemacht und nur den PFC200(8212) eingefügt (es erscheint dann ein leerer Kbus und eine serielle Schnittstelle COM1). Dann hab ich mich am Controller eingeloggt und den Kbus (Rechtsklick: Geräte suchen) mit allen Modulen automatisch ergänzen lassen. Bei den leeren Modulen hab ich dann das E/A-Abbild in csv exportiert. Dasselbe hab ich bei meinem alten "PFC200 SL" Projekt gemacht. Und dann in Excel alle Variablennamen in die leeren csv kopiert und danach wieder im neuen Projekt importiert. Dann hab ich noch alle Programmblöcke, Tasks, Visualisierungen und auch Modbus TCP Master u. Slave und auch Modbus COM Port Master und Slave in das neue Projekt kopiert. Weiters hab ich alle notwendigen Bibliotheken im Bibliotheksverwalter eingefügt. Dann noch ein paar kleine Fehler korrigiert (ich musst einen anderen Block zum Lesen der Uhrzeit nehmen) bis ich das neue Projekt fehlerfrei übersetzen konnte. Dann konnte ich es auf den Wago Controller übertragen und direkt starten. Es sieht so aus, dass alles läuft. Gruß annD

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(); } }

Hello to all, I'm totally new to Codesys, but I do have some PLC programming experience, mosty with Siemens TIA and STEP7. I have just installed Codesys 3.5. sp19 and I have downloaded example with Ethernet Rockwell 1734AENT. The example can be found here: https://forge.codesys.com/prj/codesys-example/rockwell-1734-c/home/Home/ After opening, I had to manually update devices (Device, Ethernet, IP Scanner, EthernetIP adapter). However, when trying to build the project, I get the following errors: [WARNING] CODESYS_EtherNetIP_Rockwell1734AENT: Library Manager [Device: PLC Logic: Application]: C0100: Library System_VisuElemXYChart has not been added to the Library Manager, or no valid license could be found [WARNING] CODESYS_EtherNetIP_Rockwell1734AENT: Library Manager [Device: PLC Logic: Application]: C0100: Library system_visuinputs has not been added to the Library Manager, or no valid license could be found [ERROR] iodrvethernetip, 4.4.1.0 (3s - smart software solutions gmbh): ServiceCycle [IoDrvEtherNetIP]: C0040: Function 'ProcessUpdateConfigurationQueue' requires exactly '1' inputs [ERROR] iodrvethernetip, 4.4.1.0 (3s - smart software solutions gmbh): IoDrvStartBusCycle [IoDrvEtherNetIP]: C0040: Function 'GenerateRandomUINT' requires exactly '2' inputs [ERROR] iodrvethernetip, 4.4.1.0 (3s - smart software solutions gmbh): Cyclic [GenericServiceUnConnected]: C0040: Function 'GenerateRandomUINT' requires exactly '2' inputs [ERROR] cip object, 4.4.1.0 (3s - smart software solutions gmbh): ForwardOpenService [ConnectionManager]: C0040: Function 'GetAssemblies' requires exactly '3' inputs [ERROR] iodrvethernetipadapter, 4.4.0.0 (3s - smart software solutions gmbh): ServiceCycle [IoDrvEtherNetIPAdapter]: C0040: Function 'GenerateRandomUINT' requires exactly '2' inputs [ERROR] iodrvethernetip, 4.4.1.0 (3s - smart software solutions gmbh): SetupStructuredIOMapping [RemoteAdapter]: C0040: Function 'MallocData' requires exactly '1' inputs [ERROR] iodrvethernetip, 4.4.1.0 (3s - smart software solutions gmbh): SetupStructuredIOMapping [RemoteAdapter]: C0040: Function 'MallocData' requires exactly '1' inputs Compile complete -- 7 errors, 13 warnings Build complete -- 7 errors, 13 warnings : no download possible!
