Hi, I am trying to use webvisu to be able to access the HMI from the browser. But when I add the webvisu object and go online, I can no longer start the app. No error message in the ctrlx engineering but if I go to the logbook, I get this error: We have the license for webvisu installed: If I delete the webvisu object and then go online everything is working. Can you help me? Thanks, kevin

Hello Shepherd, I should update the ctrlX but it is currently running in production and having never done that before I don't want to make a mistake. For the moment I manage to get around the problem by using data layer requests with an inject true every 500ms by detecting a rising edge instead of using the data layer subscribe The problem is therefore on standby for the moment. I will wait for a production shutdown. How long does an update last? Are there sometimes problems or important elements to take into account before updating? Thanks for your help, Kevin.

Hello Shepherd, thank you for your reply. Are different subscription configurations added or one used for accessing several nodes? There is only one subscription to a CtrlX but other configuration nodes (SQL database, HTTP requests) Which version of your system apps and Node-RED app is used? Could you please set your logbook to persistent and provide a system report (mentioned in second half of this post) after the crash? I don't have this option : I found a temporary workaround. If instead of using a Data Layer subscription, I use an inject node with a repetition interval every 500ms and use a Data Layer request, it works. You will find the flow in attachment if that helps Thanks, Kevin.

Hi, I've a problem with node-red on Ctrlx. When I try to add a new Data Layer Subscription, the CtrlX crash and restart when I deploy. When the CtrlX is restarted, the added object is deleted from node-red. I already have 59 subscriptions which work but it crashes when I add the 60th. If I remove one and then add the new it works. Can you help me? Thanks, Kevin
