Hello,

This Solution is what you are looking for, using SFB4 in FB1.

code]FUNCTION_BLOCK FB1

// Block Parameters
VAR_INPUT
// Input Parameters

END_VAR

VAR_IN_OUT
// I/O Parameters
Start: bool;

END_VAR
VAR
// Static Variables
T_imp:SFB4;


END_VAR

// Statement Section

T_imp (IN:= Start , PT:=t#10s );

IF (t_imp.q =1) THEN
Start := false;
END_IF;
;
END_FUNCTION_BLOCK[/code]

I hope it helps,

I have one question ,for example i wants to call one fb which has multiple input and output declaration means, do i need to manually type the input and output !!!.

 I think you should do it manually, there is no automatic way.But, good news is that , you don't need to link all inputs and outputs to external variables.Like a PID controller block, you can keep most the parameters as their default value.See the attached file.

Is it possible, if I entered that stat variable name and put enter then called fb should come like a ladder logic..
