May I use state machine as following:

SEQ1: process ( CLK_IN, F_RESET )
	     begin
		      if ( F_RESET = '0' ) then
					CURRENT_STATE <= INITWAIT;
	                  elsif ( CLK_IN'EVENT and CLK_IN = '1' )then
				   CURRENT_STATE <= NEXT_STATE;
	                  end if;
       end process;
	
  SEQ2:  process ( CLK_IN, F_RESET )
         begin
			
         if ( CLK_IN'EVENT and CLK_IN = '1' )then			
			case CURRENT_STATE is
			   when INITWAIT =>
				   if ( INIT_CON2 = 1023 ) then
				           NEXT_STATE <= CONMOD;
				else 
                                                         NEXT_STATE <= INITWAIT;	
                                                end if;
                                        when  CONMOD  =>

Since I have to generate some control signals in the second process and I don't want to get any latchs.

Thanks

first, according to the upon code, there is no need to use FSM.
It is so clear that FSM is uneeded.

Genraly, in FSM implementaion the CASE statement should be declared in async process. In order to avoid any LATCHs you cover all the case posibilties and ALYAWS use in CASE the OTHER...

the first proc looks fine. the second process can be simply a combinational logic process. following article gives a very good review.

Thank you very much all.

I used this way and realized what I want.
