Hi!

I'm testing IOT2040 for 3 weeks now. But I'm still not convinced that this one is stable and can be used in the Industry.
I tried to use the  xx.xx.xx.xx:1880/ui and use the Node-red own dashboard.
I have a S7-1200 PLC with a simple SINUS calculation changing each second.

The value is then changing between -1 and +1.

I made a Dashboard Chart and a Dashboard Gauge  showing the same variable (tag).

Everything looks nice for a while but after 1 or 2 minutes the Dachboard Chart freezes and thows a constant line, the chart is not updating any more.
I have tried to filter the value to 2 decimals with java script, send the value each second eith Trigger node on 100ms. trying diffetent chart time from 2 / 5 / 10 minutes. 
Nothing helps. 

When I make some change to Node-red and deploy, the Chart responds well and is showing my curve for a short periode of time, then freezing again.

Can some one help me with that ? 
 

Same issue here,

Charts are freezing after 15-16 hours while having one data point each minute.
While the gauge node is giving the correct data and a .csv file continues writing.
Conclusion, the IOT2040 is not freezing and node-red is not freezing.
I've updated the dashboard node to 2.29.1 today.
lets see what it brings.

CU Wim.
