Objects Chart doesn't work on my HMI Application

Hi everyone, I'm Antonio and I've been using plcnext for a while.

Setup used: Plcnext Engineer 2021.9

                 Plc 3152 HW02 with firmware 2021.9 update

I have correctly configured the data logger parameters in plcnext, if I extract the .db file from the plc with winscp, I can view the data collected by the logger, but when I try to create a chart using the data logger session, the graph does not appear .


I am attaching a screenshot:

thank you. Best regards Antonio.

    I just set up a project on an AXC F 2152 FW 2022.0.4 with PLCnext Engineer version 2022.0.1.

    SENSORE1 is an INT

    Hi Martin, thanks for your reply, I do not see anything on the web page, the graph does not appear, nor the abscissa and ordinate axes, the page is blank.


    Yes, SENSORE 1 Is a INT. Can you telo me how did you define SENSOR1, Local or external?

    Now, i cant upload a screenshot.

    Hi martin,

    I set up a project, then I created the datalogger session, defined an INT variable and created the HMI page with the graph, but when I load the Web Based view the page is blank.

    I attach screenshots if it helps.

    I have updated the plcnext version to 2022.0.9 and the plc controller at 2022.0.5 .

    In my case the variable SENSORE1 was a Local variable in the Main program.

    Is it only the Chart object that does not display? Do simpler objects like Text fields appear on the web pages?

  • rufusrufus

    yes sure , my HMI app is composed by 8 pages , and work everything well, so yes it's just chart object does not work .

  • rufusrufus

    I solved , Simply check the Plcnext Project version, in my case, i started the project with 00/2020 , and so i must replace the controller version , from Component Tab , with the correct version, 00/2022.


    Thanks Martin for your help.
