Variable Address

[Google Code Exporter]

Hello!

I have a problem. How can i change address in the loop (arduino 103) ?
I try, but dosn't work: (Always read the Address 1 and not read Address 2)

unsigned int modbusaddress = 1;

void setup()
{
.........
modbus_construct(packet1, modbusaddress, READ_HOLDING_REGISTERS, 0, 1, 
readRegs);
.......
void loop()
{
  modbusaddress = 2;  
  modbus_update();
  ...
}

Somebody help me please!
Thanks

This is not a defect. You are using the functions incorrectly. Use a different 
packet when polling different id addresses, functions or register addresses. 
See the library examples and check out the forum thread:
