What needs to change in the code to have a digital input to use in Scada ?

Code :

bool func_D2(const char *itemID, const opcOperation opcOP, const bool value){
static bool ledValue_D2 = false;
if (opcOP == opc_opwrite) {
ledValue_D2 = value;
if (ledValue_D2)
digitalWrite(pin_D2, LOW);
else
digitalWrite(pin_D2, HIGH);
}
else
return ledValue_D2;
}

What exactly does the bold part mean?

Are you referring to a specific Scada program or function? If so post a link so we can read its specification.

In an Arduino a digital input is usually detected with digitalRead()

How to add delay to pin output ?
bool func_D2(const char *itemID, const opcOperation opcOP, const bool value){
static bool ledValue_D2 = false;
if (opcOP == opc_opwrite) {
ledValue_D2 = value;
if (ledValue_D2)
digitalWrite(pin_D2, LOW);
delay(2000);
digitalWrite(pin_D2, LOW);
else
digitalWrite(pin_D2, HIGH);
delay(2000);
digitalWrite(pin_D2, HIGH);
}
else
return ledValue_D2;
}

Why this code does not work how to make the code by holding on HIGH-LOW
