I don't have time to go through the whole manual but as I said earlier, the servo drive does not support any of the modes needed for SoftMotion Light to work. If you want to use the full SoftMotion, you could use SMC_Homing function block to do the homing. This function block does not use the Homing Mode. It still uses the CSP mode and does the logic in Codesys runtime instead of in the servo drive. Read the documentation about it to see if it fits your needs. But if your controller only supports SoftMotion Light, I am afraid you will not be able to use the i950. I do a lot of motion stuff with different servo brands. Some support all the modes needed for SoftMotion Light and some don't. You really need to make sure the modes are supported before choosing a brand over another. I tend not to use brand specific controllers in order not to be limited by their supported features. I usually choose a PC (Linux or Windows) and install the Codesys runtime and licences myself. This is the most flexible way to use Codesys in my opinion. Depending on how many axes are needed in your project, a full SoftMotion license may not be more expensive than SoftMotion Light because SoftMotion is available as Application based license whereas SoftMotion Light is not. But of course, SoftMotion is harder on the CPU than SoftMotion Light.

Hi I have done some tests and i realised that it's an issue with the visualizator simulator because i uploaded the program to a device and tried to see on the Web browser and I see correcctlu the images of the image pool of the library. I post this for anyone that have the same problem.

I need some help and link tu tutorial I have no idea about codesys . I want to do in ST. I am using CAN RAW library from IFM . On following SS there is red triangle on CAN as well.

Post by josul on Web Client HTTPS Communication Issue ^{CODESYS Forge talk (Post)}
Web Client Library Documentation Company: 3S - Smart Software Solutions GmbH Title: Web Client Version: 1.0.1.7 Categories: Application|Utils Namespace: WEB_CLIENT Author: 3S - Smart Software Solutions GmbH Placeholder: WebClient I encountered an issue using this library above. Note it is now part of Codesys IIoT Libraries SL in the form of Web Client SL, but I am not using this version. I was sending Content-Type: application/json, HTTP POST using a HTTPS URL. No issue observed initially, successful operation. At some point operation stopped and the codesyscontrol.log file started to accumulate errors: ERROR: TlsCreateContext2: Failed to save context. An application reset failed to resume operation and I was unable observe any TCP connection forming to a destination port 443. The error appeared as a TCP_INIT error. I can find no details as to what may have happened or why a reset of the PLC application did not resume operation. Testing with a curl operation proved to be successful, so I am confident there was no fundamental networking issue preventing a TCP connection forming. The solution was to reboot the hardware itself, but this is not satisfactory in the long term. Is there any description of the TLS error I received? Is there any suggestion here that there might be an issue with certificates? Any advice or information is appreciated.

Post by etienneneu on loading delay with the option "check client animations and overlay of native elements" ^{CODESYS Forge talk (Post)}
Hey NicolaG_89, thanks for the tip. But I have seen in the developer tools of the Webclient that a multiple fetching of the image and script data occurs when changing frames (HTTP code 304 NOT Modified), although these are already in the clients cache, which leads to unnecessary loading of resources from the web server. This behavior can also be found if the option “Support client animations and overlay of native elements” is deactivated, but this does not lead to such long delays. I had already tested loading all Visu elements so that everything was fetched once before they could be used. But that didn't help either. To prevent this behavior (permanent fetching), I have used a different way of switching the Visu elements in the VisuDemo Project, which also uses HTML5 control elements. I implemented this with the visibility of entire Visu elements. As a result, it only has to be fetched once and does not have to be fetched again when reloading. But I am still unsure about this implementation if the scope of the visualization becomes larger, as the Codesys visualization documentation advises against using many invisible elements. Best regards Etienne
