Wincc flexible 2008 internal tag to PLC

Hi!

I want  read the internal tag from HMI to PLC.

HMI program  in Wincc flexible 2008

PLC program  in Simatic manager.

yes,

i used wincc flexible runtime advanced.

Hello siemensuiapl,

what's the reason for not using a PLC-tag instead?

Depending on the HMI-tag (changing interval) you can go to Properties > Events and add the system function SetTag to the event "Value change" to write the value of the HMI-tag to the PLC-tag.

Hi,

If I remember correctly, the "Change value" function does not work with internal tags; only with external tags.

But test it out and if it does not work, please explain why you need this function and perhaps people here can come up with a suggestion.

Sir,

Actually what i need

Running Recipe tag taken from wincc flexible run time software.

Customer select that  recipe selection in wincc flexible run time , That recipe tag (IO field) is a internal tag.

How to use this internal tag in Communicated PLC.

Hi,

If I remember correctly, the "Change value" function does not work with internal tags; only with external tags.

you are right.

Siemensuiapl, so operator writes some text to the internal string-tag and then starts the process with a button or is there a signal from the PLC? If this is the sequence you can use the start-signal to write the RecipeName_Running to a PLC-tag.

sorry sir,

I didn't understand.

Can you explain with example.

Hello siemensuiapl, 

siemensuiapl

sorry sir,

I didn't understand.

Can you explain with example.

one screenshot you posted shows an IO field with "Running Recipe Name" which is linked to an internal tag.

Operator has to write some text to this field? 

Is there already a process running when writing this text or is the process started after writing this text?

What is the text actually used for, how is the procedure?

This text was  already written in running process.

This text  used for select product identification.

Now i want the text for log the  loss report product wise selection.
