Why does not FC work?

Dear Sir/Madam;

I wrote a program in FC; and in OB I call this FC Three times.

In Network 2, I call it two times in a sequent. But In the first calling the commands does not work. Also I124 does not make any qouit.

Can anyone explain this?

Best Regards...

 Hello ,

 First you are in the wrong conference but no problem,

 Second are you sure that FC you have downloaded to the CPU?

 In online mode how is?

 Why you call three times Q124.0 and Q124.1?

What you are doing is dangerous!!

To explain.... (example)

IF I124.5 THEN
{
  Q124.0 := I124.0
  Q124.1 := I124.1
}

When I124.5 is TRUE then the outputs can be switched on and off. If however I124.5 goes off the outputs *** remain in the last state they were switched to ***.

Back to your question..
What do you mean by saying "But In the first calling the commands does not work." How do you know it is not functioning?

Firstly Thank all of you who answered to my question.

And ı will try why I need a this program like that.

This is a hydraulic platform. And there are two control box. one of them on cabinet on which the workers are and the other one of them is electricity control box.

And the control unit on the platform will always work. 

But the control unit on the electricity box will work if the worker makes a switch on on the cabinet control box.

  Hello Senol,

The easy way is to use only one of your FC and put in parallel the both input, the inputs on the platform to be operated only with the switch, you put this input in series to enable.

                                            Control unit Platform E124.0

----+-----------------------------------I        I-----------------+------------------ GOUP FC1

         Switch E124.5        Control unit electricity box E125.0

      I-----------I  /  I-------------------I        I------------------I

this as I understand it
