//Assume:
// "tasto1" as boolean tag manipulated by HMI
// "toggle" as boolean tag used by PLC

if ("tasto1" = true)
then //TOGGLE SWITCH BY BUTTON
  "tasto1" := false; //ready for next trigger
  "toggle" := not "toggle"; //change state
end_if;

Sorry for not making it more clear. My suggestion does not add to the HTML. It takes away from it.

The web server now interact with the PLC by %M30.0. In your PLC program you have %M30.0 to activate %Q0.0. My suggestion is to solve your problem in the PLC.

Make the button to ONLY make %M30.0 go to true.

Review:

Side note: SCL is a language in the PLC, just like LAD is a language.

hi, db

sorry again.

i was make program ladar as you show  and in plc simulation its working perfect.

but i not know where i need add SCL ?

and now my html program look like this.

is it ok ?

but doing this its not working from html.

i useing tia portal v14.

Have a look at the animated GIF for results from a live PLC.

Please remember to delete the DBs that are linked to web page. Then again generate them. Do this each time you make a change in the HTML and related codes.

Perhaps ZIP your project and add it on this forum.
Please include the web page HTML.

It would be much helpful if you make a full description of what you have as a problem; include pictures. TIP: You can use an application such as ShareX to make screen captures or 'video' GIF.

@anyone - please be so kind to help this user. Thank you.
