SIOC "IF" Question

Hi,
Jim is right, boolean algebra rules dictates that, read more about that here:

Hi Jim,

Is it possible to have a SIOC IF statement without an ELSE statement? This is because, earlier in the script, I have said ELSE &REF=0. So, is there reall a need to repeat the ELSE statement? It just causes unwatned difficulties.

Yes, of course. The ELSE part is optional (like in most programming languages).
Just write

Code:

---

IF condition
{
  statement
}

Hiya Jim,

Thanks for that post. I have made an amendment to mr original script, look below:

Code:

---

Var 7675, name REF, Link IOCARD_OUT, Output 4 // REF LED
Var 7002, name OP, Link IOCARD_OUT, Output 5 // OP LED
Var 9991, name OPSW, Link IOCARD_SW, Input 29, Type I // OP SW
Var 8881, name REFSW, Link IOCARD_SW, Input 28, Type I // REF SW
Var 9090, name Chain5, Link IOCARD_SW, Input 20 // Chain 5 Selector
Var 7890, name Chain4, Link IOCARD_SW, Input 26 // Chain 4 Selector
Var 7665, name Chain3, Link IOCARD_SW, Input 25 // Chain 3 Selector
Var 7605, name Chain2, Link IOCARD_SW, Input 24 // Chain 2 Selector
Var 7645, name Chain1, Link IOCARD_SW, Input 23 // Chain 1 Selector
Var 9888, Link FSUIPC_IN, Offset $C28D, Length 1 // Cloud Precipitation Rate (1)
{
C0 = V9991 = 1
  C1 = V8881 = 1
    IF C0 OR C1
 {
  L0 = V9888 // FSUIPC L0 = v9888 
  IF L0 <= 3    // First sector
  {
IF L0 > 0
{
  IF &Chain1 = 1
  {
    &REF = 1
  }
    IF L0 > 3
    {
  &REF = 0 OR 1
  &BlinkLed = 500000
  &BlinkLed = TIMER 0 -1 40
  ELSE
    {
    &REF = 0
    }
    }
  }
 }
}

Var 9077, name BlinkLed
{
  L0 = MOD &BlinkLed 2
  IF L0 = 0
  {
    &REF = 0
  }
  ELSE
  {
    &REF = 0 OR 1
  }
}
}

I want this code to achieve the following:

- LED ONLY Lights if Precipitation is 1-3

- LED ONLY Blinks if Precipitation is MORE than 3

- LED stops blinking if turbulence drops below three

- LED is OFF if there is no Turbulence (=0)

Does my script achieve this? I think yes to all of them, with the exception of the second to last requirement (stop code).

Jack,
Just a tip to help you:
Make sure you indent each line properly. Your scripts are very hard to read because you do not adhere to normal programming practices.
Use a fixed number of spaces to indent each block, do not use tabs. Normally one uses 2 or 4 spaces to indent a block, like this:

Code:

---

IF condition
{
  IF condition  // two spaces at the beginning of this line, because this is the first block
  {
    statement  // 4 spaces at the beginning of this line because this is a block within a block
  }
  ELSE
  {
    statement
  }
}

rgrds,
Nico

Hi Nico,

Yes you are correct, I have made a few tweaks to my script and have noticed that the brackets were messy.

In other news...

I have tried the following SIOC script, and absolutely nothing happens in IOCPConsole Log, whatever the Turbulence is set to. Any ideas?

Code:

---

Var 7675, name REF, Link IOCARD_OUT, Output 4 // REF LED
Var 9888, Link FSUIPC_IN, Offset $C28D, Length 1 // Cloud Precipitation Rate (1)
{
  L0 = V9888 // FSUIPC L0 = v9888 
  IF L0 <= 3    // First sector
 {
IF L0 > 0
  {
    &REF = 1
  }
    IF L0 > 3
  {
  &REF = 0
  &BlinkLed = 500000
  &BlinkLed = TIMER 0 -1 40
  ELSE
    {
    &REF = 0
    }
  }
 }
}

Var 9077, name BlinkLed
{
  L0 = MOD &BlinkLed 2
  IF L0 = 0
  {
    &REF = 0
  }
  ELSE
  {
    &REF = 0
  }
}

EDIT: Jim, the script compiles fine here. Also, please note the one included in THIS post is the latest version, not post #45. I will still do as you ask though, it will probably help.

Hi Jim,

It may not be correct, but at least I've had a go.

I've produced those three different scripts you asked for, here:

Code:

---

Var 9888, Link FSUIPC_IN, Offset $C28D, Length 1 // Cloud Precipitation Rate (1)
Var 222
 {
  IF v9888 >= 3
  {
&REF = 0
  &BlinkLed = 500000 // Begin value of timer
  &BlinkLed = TIMER 0 -1 40
  }
 }

Var 333 name BlinkLed
    {
  L0 = MOD &BlinkLed 2
  IF L0 = 0
    {
    &REF = 0
    }
  ELSE
      {
    &REF = 1
      }
    }

Var 13 name REF Link IOCARD_OUT Output 93

//

Var 9888, Link FSUIPC_IN, Offset $C28D, Length 1 // Cloud Precipitation Rate (1)
Var 222
 {
  IF v9888 <= 3
  {
&REF = 1
  {
  &BlinkLed = 1 // equal to end value of timer (0) + 1
  }
  }
 }

Var 13 name REF Link IOCARD_OUT Output 93

//

Var 222
 {
  IF v9888 = 0
  {
&REF = 0
  }
 }
