XScada one of open source scada .we can easily interface it with microcontroller. Here i have written an simple program to send 1 at starting then 2 after one second. This program has written in energia by using msp430 launch pad (controller--MSP430G2553). This code is also same for arduino and ARM M4 - TIVA C SERIES - TM4C123G. Serial data from msp430 launch pad is received from COM4.Here data send in a particular format .data after 'W' and ';' will only see in scada.

{
Serial.begin(9600); // starts serial
communication @ baud rate of 9600
Serial.print("[1;1;W;1]");
delay(1000);
}
void loop() {
Serial.print("[1;1;W;");
Serial.write('2');
Serial.print("]");
delay(1000); //
delay in between reads for stability
}
