They are using node-red_1.18.0+3.0.2 and 1.20 in the core (not sure about the release). They have two sheets with an subscrbtion on each, and the values are changed every 1minutes. I did not know that it is possible to retrigger a subscribtion in Node-RED? I think this item in the log is added each time it works: info 2023-08-29T08:14:31.876093+02:00 2023/08/29 08:14:31 GET /api/v1/status GetStatus 17.18Âµs info 2023-08-29T08:14:31.832164+02:00 2023/08/29 08:14:31 GET /api/v1/status GetStatus 17.16Âµs info 2023-08-29T08:13:31.874623+02:00 2023/08/29 08:13:31 GET /api/v1/status GetStatus 16.31Âµs info 2023-08-29T08:13:31.832228+02:00 2023/08/29 08:13:31 GET /api/v1/status GetStatus 14.92Âµs But the strange thing is that they dont get DL_INVALID_ADDRESS all the time, most of the reads works, but not all of them.

I have a customer that has a Node-RED flow that subscribes and reads datalayer nodes. It works most of the time, but now and again they are getting DL_INVALID_ADDRESS when reading PLC variables. They are getting a few errors in the logbook, but then it starts working again info 2023-08-29T06:34:52.147288+02:00 29 Aug 06:34:52 - [error] [ctrlx-datalayer-subscribe:TransactionID] DL_INVALID_ADDRESS info 2023-08-29T06:34:52.147288+02:00 29 Aug 06:34:52 - [error] [ctrlx-datalayer-subscribe:PlcState] DL_INVALID_ADDRESS info 2023-08-29T06:34:42.128743+02:00 29 Aug 06:34:42 - [error] [ctrlx-datalayer-subscribe:TransactionID] DL_INVALID_ADDRESS info 2023-08-29T06:34:42.124838+02:00 29 Aug 06:34:42 - [error] [ctrlx-datalayer-subscribe:PlcState] DL_INVALID_ADDRESS We are not really sure how to track down what is happening here, anyone have any ideas? I have the tar file from the core but I'm not allowed to share it publicly.

Hello, The api documentation is avaiable from here (requires login on the WebIQ - page): https://www.smart-hmi.com/user/download/deliver/docs/documentation-webiq-visuals-reference-2.14-3d30/shmi.visuals.core.ItemManager.html And the readValue method is probably what you want

1. The () => is an arrow function, it works in all major browsers unless you run an ancient version (And then you really should update due to security fixes): https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions 2. The line window.location.href will clear the timer and then redirect to the WebIQ page, so no need to clear the timer.
