Greetings, I am currently utilizing a Hitachi Micro EHV+ for a small-scale project and am seeking to implement a Web visualization using Codesys V3.5 SP13 Patch 2. While the Visu screen functions properly within Codesys, I encounter a blank page when attempting to access the web visualization in a web browser. The settings for the web visualization include an Update rate of 5000ms and a Default communication size of 100000. Additionally, under the Visu_Task tab, the Priority is set to 3 and the Visu_Task interval is configured at 2500ms. I am using the latest version of Google Chrome with enabled Javascript and HTML5 capabilities. Any suggestions or recommendations on how to resolve this issue would be greatly appreciated.
Which type of HTML code are you inputting into your web browser?
When entering the browser, what HTML code are you typing? Click here to access http://192.168.0.5/webvisu.htm/ for more information.
When choosing a port for accessing a website, remember to use port 8080. For instance, you can type in 192.168.0.43:8080/webvisu.htm.
When accessing a web server, it may be necessary to specify a port number such as 8080. For instance, you can visit a webpage by typing in the following format: 192.168.0.43:8080/webvisu.htm. However, some users have found that omitting the port number and simply entering the IP address like this "http://192.168.0.5/webvisu.htm" works just fine. The reason behind this discrepancy remains unclear.
When working with a web server, it is important to understand the process of matching requested URLs to the appropriate response. Web servers commonly use file extensions such as .htm to correspond with the requested URLs. For example, if you load a page with a /slash, it may appear as though you are requesting a different resource. In many cases, the presence of a slash indicates a request to list a directory. This is a common reality of web server operations.
You seem to have your settings quite structured, which is good. However, this issue might not be related to your configuration but instead might be a problem with the browser compatibility or network settings. Firstly, try to recheck your firewall rules and ensure that there are no restrictions for your web visualization to load. This includes checking if ports that CODESYS uses (typically 1217 & 8080) are not blocked. You should also verify whether the WebVisu service is enabled in your project settings. If all these are already in place, test your project with another browser besides Chrome, like Firefox or Edge, to investigate any potential browser compatibility issues. Lastly, ensure that you're accessing the WebVisu using the correct IP address in your browser. Hope this helps get you on the right track!
Hi, this issue that you're facing could potentially be related to the network settings on your WebVisu. Make sure that your target system is set to the correct IP configuration that matches your network. You should also check whether the port used for the HTTP server on your target device is open and accessible, as this can be a common culprit. Additionally, deselect the 'Use HTTPS Security' option if it's enabled, and try again. I also recommend trying a different browser just to see if Chrome is the issue, or clearing your cache and cookies, as these have sometimes been known to cause similar problems. Lastly, ensure that your firewall isn't blocking access to the visualization.
It sounds like you've done some thorough troubleshooting already! Have you checked if the web visualization settings in Codesys are correctly configured to be accessible over the network? Sometimes firewall or network configuration can interfere with how the visualization loads in a browser. Also, try accessing it from a different browser or device to rule out any browser-specific issues. Lastly, ensure that the web server is properly enabled and running within your Codesys project settings. Good luck, and I hope you get it sorted out soon!
It sounds like you've done a good job setting things up, but have you checked the project’s execution mode? Sometimes, the web visualization can display a blank page if the project isn’t in 'Run' mode or if there's a mismatch in the browser’s compatibility settings. Additionally, ensure that the visualization elements are correctly linked and that there are no missing resources. It might also help to check the console logs in Chrome for any errors that could give you a clue about what’s going wrong. If all else fails, trying to access the visualization from a different browser or device could provide more insight. Good luck!
