What is not working?

Upload you script.

First hint: you do not reset tag_3 to 0 again... 

Dear IBN-service,

yes I did I reseted the tag_3 to zero by an other button but in vain.

who is not working is when we put a false tag in IF instruction its work

                                     when we put a true tag in IF instruction doesn't work

thanks to help me

IBN-Service

Upload your script

My idea is, that you do not understand bool AND - logic?

Check this für logic table of gates: https://en.wikipedia.org/wiki/Logic_gate

Dear IBN-service,

may be you don't understand my question,

in the second logic I activate tag_1 and tag_2 from PLCSIM  then when I push a botton who is connected to script  tag_3 dosen't active I dont know why???

Regards

sorry but really there is a problem.

even when write  IF  tag_1 =1 then

                                 tag_3=1

                                end if

doesn't work !!!!!!!!  it's work only with tag_x= Zero

Hello hag010,

off course sometime in Siemens software there are some little bugs

....but in this case problem don't came from Siemens....

WinccFlexible use for Scripting VBS, in VBS boolean data type is not 0/1 but true-false (MSDN reference).

If instead of  :

<tag_1=1>

you write :

<tag_1=true>

all will be OK.

As you can read in (MSDN reference).  if you want to use 0-1 value TRUE is not 1 but -1. So <tag_1=-1> also will work.

Try and let-us know what happens.........

dear mindware,

thanks a lot it's work fine.

yours sincerely
