Hello evreryone,

I'm using TiaV13 and a TP700 Comford panel.

Is there a way to Active a popupscreen with a plc tag?

I already tried something with a VB script:

"M_HMI_Open_Melding_Popup" = a tag from PLC To HMI

and "Pop-up screen Meldingen" = the popupscreen

But it doesn't work.

What do I miss, or is it complete wrong?

Thanks!

Hello HWEngineer,

you have a syntax error.

Use  

If SmartTags("PLC_HMI_Tag") Then

instead of

If "PLC_HMI_Tag" Then

(same goes for the second post).

Make sure the popup has enough  space to open (so it can't be larger than 600x 280 pixels when you use the opening position 200, 200).

The rest of the script looks ok.

You can drag&drop HMI tags from the "Detail view" (bottom left window) to the script, when you select the according tag table in the project tree while you have the VBS editor open.

Hi all,

I have an IPC277D with a runtime V13SP1 upd9. But i'm testing with the simulator.

I tried the syntax explained in the previous messages, put it doesn't work (but compile).

This is my script:

I tried to change syntax of If condition with = true, = 1, ="true", = "1", nothing works (but compile). But if i replace the full condition by True it works but open always the popup. I just mention that i call the script as Loaded in the main screen of application.

If someone as an idea ???

Regards.

Hello MarcoPolo01,

try setting the "Acquisition mode" of your tag to "Cyclic continuous"
(tag table > tag > Properties  > Settings).

ShowPopupScreen "Pop-up screen Releasquestion", 200,200,hmiOn, hmiAnimationOff, hmiFast

Hello MarcoPolo01,

Hi,

The tag i'm using is not a PLC Tag, it is an internal tag TIA Portal application. So i can't change Acquisition Mode.

In fact the problem is not about the tag itself, because i created also buttons on panels to set and reset the tag (bool) and also i display a light if the tag is equal to 1. the tag trigger correctly but doesn't execute the popup opening. It seems the script doesn't allow to check tag value as condition to execute the "if then else".

Hello MarcoPolo01,

yes, you can't call a script on the event "Value change" of an internal tag, *edit* when the value change is caused by another script or system function.*/edit*

Would have been helpful if you had told us you are using an internal tag. This is a thread talking about using a PLC tag and you didn't say otherwise. You could have saved yourself some time there.

If you don't want or can't use a PLC tag you need to find another trigger. Maybe connect the script to the event "Input finished" of the O/I-field/button/other control where you set the internal tag.

 Hi,

Ok sorry for that but i thought the principle was the same, it was the only topic close to my problem so it is why i ask here. The important thing in my request is to trigger the script if a tag value change.

I will send a message to Siemens support directly because i really need to use script like this.

Thank you anyway.

Hello MarcoPolo01,

sorry, I might have been in a bad mood there.

To be more clear: you CAN use "Value change", but the value change has to be because the internal tag is changed by using an I/O-field, NOT by a script or system function on a button.

This might be to prevent endless loops.
