Post by mubeta on Profibus DP master with EL6731 and automatic restart of slaves ^{CODESYS Forge talk (Post)}
WHEREAS, I have already searched various posts and forums, where mostly there are few references and mostly geared toward integration in TwinCAT. I am looking for how to properly configure the EL6731 board as a DP master, (where I have its 3S license), with CoDeSys 3.5.19.x. I have three types of slaves, all integrated with their GSD descriptors. In the tab for the various slaves, I don't see options related to node restart on 'station return'. On the card manual, I read that for each slave I should be able to configure parameter 8000:2C: “8000:2C Restart behavior after DP fault Reserve, must be 0 BIT1 RW 0x00 (0dec)” However, in the project I see no way to configure this parameter, in any of the boards; and the arrays do not always have such an extensive size; most of the time they are only two or three words in size. The problem is that, after the hot reset of CoDeSys, the master restarts by starting all slave nodes, but if one or more get lost and go offline, there is then no automatic restart upon their return. I would need to figure out any solution, even via software, how to figure out that this one is back available and restart it.

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.

Post by pernockham on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
I have done the switch (linux mint, virtual windows through QEMU/KVM) now and is generally pleased. Have had problems in two areas initially. To bridge IP to the Virtual unit (solved), I overthought things initially. Solution. Configure manually a bridge in the mint-"network connections". Use that bridge in the Qemu settings as "Bridge device", "Device name": "name of the configured bridge" Figure out where to store the projects. I started out have the data in linux world (sort of) and linking it the windows with "virtio-fs". That had some serious impact though on git-handling. It seems that virtio-fs interpreted any file-path as lowercase only even if there were uppercase, resulting in git not able to sync files between its repository and the source code (it created a new file-path for me with only lowercase). Then I switch to samba-share instead and this works much better, though (git-actions) is a part that still has low performance with lots of waiting for file-actions. What should be the best way of handling the source/git? Edit to answer myself: Save the project "locally" in windows, then a lot of slow performance is avoided. Then a git-remote sync for backup.

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 alexgooi on Licensing info not available. ^{CODESYS Forge talk (Post)}
Sorry for the question, but I'm not completely getting the idea here, could you be more specific, maybe give an example? I'm now in a state where I don't have a softcontainer on my license server anymore (even after reinstalling from the Codesys-IDE). I tried reaching the webserver of Codemeter but when I do that I get redirected to http://"IP":22352 This is not reachable, afterwards I installed lynx on my Debian machine (command line only). From here I could reach the webserver and toggle the network server setting, but unfortunately this did not help. I also tried to changed the remote read setting to 1 (in the Server.ini file). But after a Codemeter reboot this is overwritten to 0. I have the feeling that it should be much easier to get a license to work, am I missing some checkbox somewhere? Is there a tutorial (or manual) that explains the licensing sequence step by step, because I'm pretty stuck.

I saved it as the same project but in a different location. I opened this "new project". I clicked on the "Direct Login from Automation Builder" button. It automatically directed me to CODESYS, where I was able to create the "Create Boot Project" but first I also clicked login again but inside CODESYS keeping the automation builder login online. Additional Information: The "Create Boot Project" function in CODESYS is used to create a project that will automatically start when the controller is booted up. To create a boot project, you must first create a new project in CODESYS. Once you have created a new project, you can then use the "Create Boot Project" function to create a boot application. The "Create Boot Project" function will create a new application that is based on the current project. The new application will be saved in the same location as the current project. You can then download the new application to the controller.

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 mtho on JSON Utilities - JSON file written with invalid structure ^{CODESYS Forge talk (Post)}
I'm using the JSON Utilities SL library to write configurations in my program to a file. I'm generating the JSON data using the builder function block and all appears to work correctly. When I write the jsondata to file, I'm finding that some of the JSON elements are not being written in the right location in the file. Rather than writing they keys under the parent object, they get written outside the root JSON object at the end of the file. If I then try to read the file back into the program, I get an invalid_structure error. I don't get any errors when populating the JSON data or when writing the file. I attached an example of the JSON writer output. The problems begin with key P200. Each P200 should go under MBR1 through MBR3. Among the rest of the keys, they are supposed to be under different parent objects. I am using default values for wsLineBreak and encoding.

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.

The hole setup is made by 3s. So its a comination of one not two. If Epis decide not to support extra licence whats then the funtion of providing an option with a single license ?? So the idee by 3s has a flod. Epis change the system to add the Stick. I send controller inc stick to Epis. On my software i can see the stick. An then you tel me i need a other license to use an license ?? Makes completly no sense. Codesys should be flexible but is not. I tried Delta. But has no HMI and has its own Codesys ?? Why ?? Then i tried Crist. The block there own system by a password. But dont know the password and cant switch it off. At the end the want me to pay for support to solve ther own made problem. So i send it al back. The extra license is adviced by 3s . Now a few month later still no working solution.

Hello everyone. I hope this is the right place to ask for help, this error is causing me a great amount of time loss and I really would like to end this nightmare. I don't know why but at times if I try to Browse -> Display Cross Reference on a variable Codesys just crashes. I'll attach the file with the complete crash report hoping someone can figure why it happend. I think that the unhandled exception comes from the PersisranceManager Module and is connected with the other big problem I'm facing: I cannot refactor in my project, if I'll try to refactor a POU name the whole POU will become "frozen", it's like its desynchronizing from the project and the project cannot find the pointer to the POU once I refactor it. And when I open the project a warning pop-up will show up with the frozen POUs name, but I cannot figure out what the warning is telling me. I'll attach every warning and error pop up the project is showing me, and thanks in advance to anyone who can figure something out.
