LOOP - BLINK -MODBUS RTU
-
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?

Your question isn't really related to this forum. This is about Modbus4J, the Java library.
