WebIQ: Trend, I can't see data

I've got a trend object but I can not see the signal from a OPC UA source, t.e. cpu-utilisation-percent:

Other signals are working well, t.e. DSaw.

The value of cpu-utilisation-percent is reading well, but will not be displayed in the trend object. The date and time of the CORE is set correctly.

As an attachment you will find a easy WebIQ project.

Used System, App-Data

  • RM21.11.2
  • WebIQ Server version 2.10

Hello LunatiX,

for a variable to be shown in a Trend Display the limits have to be set:

Re: WebIQ: Trend, I can't see data

Hi,

 

I still have the problem: using the WebIQ lolachost server the trend function works but if I use the server inside CtrlX ( the app ) it doesn't work using the same variable "SinVar" which is an internal var. But also using a var coming from the PLC it doesn't work either.

Please let me know what I'm doing wrong and hoe I could make the trend run connected to the CtrlX.

Many thanks

Giuseppe

Re: WebIQ: Trend, I can't see data

Did you set the min/max values for the SinVar imported from ctrlX correctly?
