I am a beginner working with the program Tia Portal

How is this code written in : Ladder Tia portal v16

Yes exactly

Faysal.M

I have five DFB with schneider I want to program it with: Ladder Step 7

You should find it easy to convert these code into LAD yourself. The code is very straightforward.

Assume this as your template..

// sample structured text
if A1 and A2 and not A3 then
  SET(B1);
  RESET(B2);
end_if;

This translates to..

   A1       A2       A3         B1 
--|   |----|   |----| / |--|--( S )
                           |
                           |    B2
                           |--( R )

thanks 

and this how

Which scheider software is it from?

It looks like a timer instruction:

IN: tag to start the timer

PT: Preset time

Q: Output

Hello Faysal;

Kal A. is quite right, this is a structured text timer instruction.

If I may provide a translation from the screenshot you posted earlier:

          (Incoherence test)

***********************************************************************************

(*as soon as both signals fcf and fco are true at the same moment

we begin to caculate the elapsed time (preinc) with time = 1s*)

Timer_I (IN:= (fcf AND fco), PT:= time_inc, Q=> preinc);

(*if the elapsed time = time_inc, we signal the incoherence*)

IF preinc THEN

  set (incoh);

END_IF;

*************************************************************************************

The reason we are asking which Schneider software Unity Pro, SoMachine...) and which timer instruction was used for this code is that it would be easier to match it with equivalent Siemens timer instructions that we could use in the ladder translation of the code.

Hope this helps,

I want to know how to do it on LADDER tia portal
