LOOP - BLINK - AUTOMATION

Hi,

I have a one question. I use the modbus serial for comunication. It is script:

#include <ModbusSlave.h>
/* First step MBS: create an instance */
ModbusSlave mbs;
/* slave registers */
enum {

MB_CTRL, /* Led control on, off or blink */
MB_TIME, /* blink time in milliseconds */
MB_CNT, /* count the number of blinks */
MB_REGS /* total number of registers on slave */

};

int regs[MB_REGS];
int ledPin = 13;

void setup()
{

/* the Modbus slave configuration parameters */
const unsigned char SLAVE = 1;
const long BAUD = 9600;
const char PARITY = 'n';
const char TXENPIN = 1;
/* Second step MBS: configure */
mbs.configure(SLAVE,BAUD,PARITY,TXENPIN);
pinMode(ledPin, OUTPUT);

}

void loop()

{

/* Third and las step MBS: update in loop*/

mbs.update(regs, MB_REGS);

if(regs[MB_CTRL]==1)

{

digitalWrite(ledPin,1);

}

else{

digitalWrite(ledPin,0);

}

}

********************
But i want a blink effect in led and i modified the script:

if(regs[MB_CTRL]==1)
{
digitalWrite(ledPin,1);
delay(3000);
digitalWrite(ledPin,0);
delay(3000);
}
else{
digitalWrite(ledPin,0);
}
}

Well, when i set the bit 1, the led blink but it don't enter in the else.

Anyone had the same problem with supervisory and script?
