I have the same problem in that I can connect to the eWon and ping the controller IP Address, however I cant connect through CodeSys. I'm using Gateway-1 which is configured to use "IP-Address: localhost" and "Port: 1217". Rather than scanning the network for devices, I enter the IP Address of the device, codesys returns a "No Device is repsonding..." message. See attached. I'm wondering if the IP-Address used Gateway-1 should be "localhost" or the WAN/LAN IP of the eWon? Thanks for the help MC

Post by dominggus on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
I still have the same problem even when updating to CODESYS Recipes 4.3.0.0. My scenario: I'm trying to save/load an array of structs using the Visu: - Execute Command > "SaveRecipeAs" works properly - Execute Command > "LoadWriteRecipe" works not entirely: the structs of array[6] and array[7] should have been empty but were duplicates of array[4] and array[5]... the struct contains 26 variables and the array's length is 30.. Maybe there is a upper limit on recipe variable count?

Nano goodmorning and thanks for the reaply, the links I have to manage are links as the following: https://192.168.1.101/u-os-app-codesys/application/visualization/webvisu.htm I saw that with Wikipedia or other web sites the tool works but not the link above.

Post by wind-11 on Problem with simulation Modbus ^{CODESYS Forge talk (Post)}
Hello everyone, I encountered a problem in the simulation while working. In a test project we set up a Modbus connection. We wanted to simulate this with test values. The connection also worked, but unfortunately the values are frozen and do not report any “current data”. (Picture attached) Since these are my first points of contact with Codesys and my colleague continues to work elsewhere, I was hoping that someone here might have an idea. Kind regards and thanks in advance.

Post by rossanoparis on RevPi CONNECT+, CODESYS, EtherCAT master "Filedbus lost synchronicity" ^{CODESYS Forge talk (Post)}
Hello @rmaas I assume, you've already verified and tuned everything regarding the EtherCAT network. In my case the problem was due to a wrong core assignement. I suggest to not use the core #0 for your EtherCAT task. The OS realtime patch, which is present on RevPi OS, uses the core #0 for its porpouses and it mustn't be used by any other task which requires realtime and deterministic features. regards Rossano

Post by dkugler on Alarm State Icon ^{CODESYS Forge talk (Post)}
thank you for pointing me to this "bug"!! I haven't recognized, the bit is reset after the first alarm is gone. I use this only for warnings, so it's not a drama, but was not correct in the past. I solved it now simply stupid by counting up a variable every time an alarm appears and decreasing it if an alarm is gone. The "warning lamp" is activated by checking the counter is > 0 The nice side effect, i'm able to show the number of active alarms in the state line now.

I bought and installed SoftMotion Light now. When I try to add a SoftMotion Light Axis to my stepper drive and I go online it shows: "The license is missing or invalid". See picture What am I doing wrong? This is the right way right? First add your EtherCat XML-File from your stepper driver and then add the SoftMotion Light axis right? Thanks for your help esave

there is a new problem with latest bootloader version.

Post by herbasso88 on WebVisu flickering ^{CODESYS Forge talk (Post)}
Good morning, I'm new on Codesys Forge, so I'm not sure if this is the right place to talk about my problem. When I open my WebVisu pages with Microsoft Edge, or Chrome, the background and also some rectangles blinking without reason!!! The application is developed with Codesys 3.5.17.10 and run on Codesys HMI, same version (3.5.17.10). After several experiments I discover that the problem happens when I made dynamic the "End of area" property of a meter object, but I can't understand why this blinking problem happens. Also, the problem is only at the WebVisu page, the "normal" VISU pages (the ones opened when Codesys HMI start) work always perfectly. Another strange thing is that the problem happens only if on the same page, where there is the meter object, there is also a trend object!?!? Codesys HMI is running on a Virtual Machine (VMware Workstation 15 player, v.15.5.6) running Windows 10 Pro N 64-bit. The blinking problem happen also if I convert the project to Codesys 3.5.20.0. This version of Codesys and Codesys HMI are installed on a Virtual Machine running Windows Server 2019 Standard 64-bit. In attachment the archive of my project. The attached project has only one page, if "Enable Counter" is not pressed the "End of area" variable of the meter is not updated in the software, and everything work well, normal VISU and WebVisu; if "Enable Counter" is pressed, the "End of area" variable of the meter is updated in the software, and the WebVisu page start blinking. I tried also to enable the "Support client animations and overlay..." property at VisualizationManager, this seems stop the blinking problem, but that property also destroy my WebPage, moving almost all the graphical object, that also seem not working anymore. I really need help to understand what I'm doing wrong, I have to develop a bigger project and I have to understand if trend objects and animated meters cannot stay in the same page. In the final project the WebVisu will be very important because the customer will use this way to access the application to monitor the process. Regards

Recipe Manager will load windows explorer view and allow file name to be typed in or existing file selected but will not create a new file or overwrite an existing. Will not create a file in the default folder or even a defined folder like "c:\recipes\" although it does properly navigate to that folder location. I made sure the folder is not read-only.

A got a larger project but this very small example makes it clear. I have a button, and after it's clicked a lamp should flip on and stays on, and when the mouse-button is released it should stay on. When I try that in the PLC_PRG it works, but when I change it to a function block (seet attched demo proj) it isn't. I'm fairly new to PLC programming but are very experienced C# engineer, but this goes above my head...

Hi, I clone a git repository with VersionUpdateFlags.SilentMode, works fine But now I want to checkout a specific commit (with branch_copy command). When using the branch_copy command there is no VersionUpdateFlags and I get this annoying "Project Environment" prompt, blocking further execution of my script without user input. I already tried something like system.prompt_answers[???] = PromptResult.Cancel but I don´t know the string I need here.. The goal is to have a script that clones a repository and compiles every tag + create compiled libraries.

Hello New W11 machine. I've tried installing and the 'Codesys installer' appeared, which basically failed. This was the exe from the Store. I've now tried installing with an old copy of SP17, which didn't try and use the Codesys installer, but has hung at the 'Install all packages added to the setup' stage. Has the exe been updated to use the Codesys installer? What is the installer? Do we think it'll work on w11? thanks, Paul

Post by wollvieh on License Activation Problems ^{CODESYS Forge talk (Post)}
on a raspberry pi delete the folder and its content before licensing. /var/opt/codesys/cmactlicense If you plug this SD card in another raspi ( which has another hw-serial number) you'll get a second empty softcontainer. This could lead to an unlicensed PFC (it could only handle one container) The solution is: To delete the /var/opt/codesys/cmactlicense directory and content of it and then aktivate the lizenz via WibuCmRau file and Lizenzmanager.

Hi Manuknecht, Did you manage to solve the problem? I’m facing the same issue with Windows RTE SoftMotion — it works fine as long as nothing else is open in Windows, but as soon as I start another application, the EtherCAT DC time and max jitter values spike, and then all axes stop. I’ve already sent a support request to CODESYS, but haven’t received a response yet.

I want to cancel the automatic address allocation for all IO mappings. If I directly set the automatic_iec_address in class ScriptIoMapping to False, the address becomes None. So I reset manual_iec_address with itselfs value. It only work with the Input IOMapping . For output, it reports an error: "Invalid address: The channel type 'Output' requires address type '%Q'." I checked the description file ,both accessRight are total same. Does anyone know what causes this?

Post by imdatatas on SMC_ERROR.SMC_AXIS_NOT_READY_FOR_MOTION when using Drive Virtual ^{CODESYS Forge talk (Post)}
@ducng, Another possible situation could be that normally there are 3 inputs for MC_Power. In your above images, I can't see the "bDriveStart" input activated. As Mr. @gseidel mentioned, you need to make sure MC_Power.Status output should be TRUE. Issuing any movement command without activating the axis would naturally result in an error. For MC_Power; You can set the Enable and bDriveStart inputs to TRUE and try turning the axis activation on and off using only the bRegulatorOn input. Regards, Imdat

Post by gseidel on MC_Phasing state explenation ^{CODESYS Forge talk (Post)}
Hi kenth1973, MC_Phasing has been improved in recent versions. I would recommend to install the latest version of SoftMotion (4.20.1.0) and test whether the problem still exists, and if so, what the error identifier is. (Also check the PLC log in this case, it might contain additional information.) Setting the internal state of the FB is not recommended, it could lead to malfunction of the FB and unintended movements of the drive. Best regards, Georg

Post by gseidel on Scara3 kinematic robot error ^{CODESYS Forge talk (Post)}
Hi aniket-b, this error has nothing to do with the scara3 kinematics, or robotics, or SoftMotion. It means that the EtherCAT bus is not synchronized. The usual cause is that the realtime of the PLC is not sufficient. See https://content.helpme-codesys.com/en/CODESYS%20SoftMotion/_sm_basic_common_errors.html for details and ways to solve the problem. You can also check the PLC log for additional information about the error. Best regards, Georg

Post by bertus on Axis directions in CNC editor not using right-hand rule? ^{CODESYS Forge talk (Post)}
Hello, Coming from robotics, I'm used to coordinate systems using the right-hand rule. But when I created below small NC program in the Codesys CNC editor, I noticed that the axis triad's Z-axis is flipped (see attached screenshot), resulting in left-hand rule. Is there a setting to change this? Or am I misunderstanding something in the CNC world? N000 G00 X0 Y0 N010 G01 X100 N020 G01 Y50 N030 G01 X0 N040 G01 Y0 N050 G01 Z25

Post by gseidel on Axis directions in CNC editor not using right-hand rule? ^{CODESYS Forge talk (Post)}
Hi bertus, the coordinate systems used in SoftMotion CNC are all right-handed. The CNC editor uses isometric projection. This can be confusing, as in your example. The y-axis seems to point into the screen, away from the viewer. However, this is just an optical effect. If you turn on the (experimental) perspective projection (must be added to the CNC tool bar using tools->customize), you can see that the coordinate system is in fact right-handed. Best regards, Georg
