      }

   }
}


When turn on power than state == 0
than if B1 on Init.... and one more if B1 on start...
when running B0 On... It's like E-Stop...
than push B1... than Start... But... It's can't running...

Please check code...

I did not check your whole program, but I did see one problem.
You have many functions like this:
Code:
void cylinder2_Dn()
{
   if(state == 0) break;
   output_high(pin_D1);
   while(!input(pin_A1)) {}
}


The problem is in this statement:
if(state == 0) break;

This is not the correct way to use the "break" statement.
See the following link
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccelng/htm/state_2.asp

I did not study your program in detail, but I think you probably
want to return from the function if the state is 0. So use the
"return" statement as shown below:

void cylinder2_Dn()
{
if(state == 0) return;
output_high(pin_D1);
while(!input(pin_A1)) {}
}

Your main problem is that you need to study the C language some more.
Before you use a statement, you need to look at example programs
and also to study the C manual.

Sorry...
Ithink...
When push E-Stop button... than B0 on...
So...
Code:
void reset()
{
   state == 0;
   output_high(pin_C5);
   output_c(0x00);
   output_d(0x00);
}
#INT_EXT
ext_isr()
{
   reset();
}


and...
Push Start Button...
INIT..... ruturn...

I cannot write your program for you. You must do it.

But you must study the C language more.

This statement does not set the variable "state" equal to 0.
state == 0;

You need to write it like this:
state = 0;

Please study the C language before you write more code.
