You can of course also implement locking (specifically releasing locks after some time automatically), but that must be done on the OPC UA server and cannot be done in the frontend as network latency, network issues and CPU performance of browsers could potentially cause deadlocks or other issues. You could then provide these as OPC UA methods and call them from the HMI via a UI Action. As mentioned before you'd still have to handle timeouts/disconnects in the browser on the server side for unlocking after inactivity.

This explains the error and possible solution: https://stackoverflow.com/a/78176180 If I were you I'd check if there is a non-module version of OpenBridge and use that - the one we used is not a module: https://demo.smart-hmi.com/openbridge/js/custom-libs/openbridge.js

Thanks @Sgilk and @HmiGuide for answering here! Just want to point out that this is actually a feature in WebIQ (and probably in most other web HMIs) that you will not get from traditional HMIs: different views on different devices like on any other website: if I look at a product on amazon.com another user can look at a different product on amazon.com. The suggested solution using PLC items is the correct way, but another solution is simply doing the same you probably have done before: have a single device that displays the HMI in a browser and use VNC from other displays to connect to it - that way all devices have the same view and you can continue working as before - without benefiting from multi-user usage (as on any other website). Most customers prefer having completely different views on different devices, because that way users can work independently of each other at different parts of the HMI or even display different parts of the HMI on different panels easily - something unheard of with legacy HMIs.

That should work (did you try?) but please note that in general these files will be removed when updating an HMI to a later version. Once again I highly recommend using the clean version of a separate program, e.g. in NodeJS, that does all the work for you as it works even when no HMI is running in a browser, but started in the server.

The CSV export is not and cannot be an HMI project so it cannot be loaded with WebIQ. As pointed out it is a completely independent NodeJS program that connects to the WebIQ Server API, retrieves the data and writes it to disk.
