Hello Peter,
we are using dateWindow function during trend refresh. Thus every time we get a new data the time widow is adjusted. So you are not able to use this attribute for custom default zoom. I suggest to follow the @cechurat recommendation and create a 3 hour trend.

Best regards,

Hello @sadilekivan ,
this issue was caused by unknown bug in the hashing algorithm during the HMI build process. This will be fixed in next version of our software. Thank you for the bug report.

It seems that configuration of the HMI Designer is OK. Please check if HMI can be generated from the HMI Designer.

• Delete the hmi directory
• Open your index.hmi.svg
• Generate the HMI using Ctrl+H
• Check if hmi directory with index.html file was generated

If this passed the problem is in the utility which calls the HMI Designer generator during compilation process in the Studio. I must prepare some better version of the script which will give us the detailed information about the error you receive.

Hello @sadilekivan ,
I have a few questions. Can you check them for me.

1. Are you able to compile the project without HMI on you laptop? Just uncheck the GenerateRexHMI in the HMI block. And compile it again.
2. Are you able to build the HMI using HMI Designer?

• Open the index.hmi.svg file in the REXYGEN HMI Designer tool.
• Open REXYGEN HMI Configuration using CTRL+E shortcutn with no selection
• In HTML export tab check Expert mode and change Output filename parameter to ../hmi/index.html
• Close the dialog using OK button
• Then press Ctrl+H for HMI generation from the HMI Designer.

3. In HMI Designer check the python version and version of the libraries using Exensions -> REXYGEN HMI -> Version Info

4. What is you Windows version?

Thank you for your input,
Best regards
Ondrej
