Hi wincc flex 2008

How can i clear multiple latched switches on screen

from a momentary push button.

Just like a pushbutton to clear all to default state.

Thanks

Hi, 

what do you mean with multiple latched push buttons.

How do you latch them with a specific bit ? (internal within wincc flexible or are they latched by an external bit)...

What you'll need to do is resetting the bit which is 'latching' them... (using ResetBit function in EVENTS of the reset button)

is it the same bit for each button ? could you maybe send an example how they are latched...

Hi

These are just simple latched switches via hmi

i have managed to use ResetBit function to clear these switches to default state from momentary push.

but i have 25 switches to reset

wincc allows maximum of 16 functions

How can i get all possible 25 to reset

Thanks

My idea was to use on event and to reset all of them.

You should reset all bits (which have activated this latch) with one event on the reset button.

Could you send me the list of tags which latches these buttons.

let say for example tag1 with address DB1.DBX 0.0 is latching button 1 and so on until DB1.DBX1.7

this means that you can send 0 to DB1.DBW0 which will deactivate the latch (using event function SetValue)...

you can try this if 'latch-tags' are grouped this way of course...

or if you want to keep your first approach you can put 16 'resetbit events' under Press and 9 'resetbit events' under Click or Release

Didn't think to use the  release of the button press

That will do fine

Thank you
