This issue has most likely a very simple solution but just now I'm stucked. I have a functionblock written in SCL language. On this block I have 5 inputs which I want to convert to an integer value.
The inputs can be seen as binary code from bit 0 to bit 4. Depending on the value from these input I want to read out a integer value.

I STL this has been a simple task but I just can't figured out to do it in SCL

Anyone who can put me on the track again?

VAR_INPUT

VAR_OUTPUT

result_out : INT;
END_VAR

BEGIN
result_out := 0;
result_out.x0 := bit0;
result_out.x1 := bit1;
result_out.x2 := bit2;
result_out.x3 := bit3;
result_out.x4 := bit4;
END_FUNCTION_BLOCK

I do not have Step 7, just TIA Portal V11 SP2 which has SCL.

A small FB with code for Portal might look like this:

[memory declarations are done differently, so forgive any syntax problems]

VAR_INPUT

bit0 : BOOL;
bit1 : BOOL;
bit2 : BOOL;
bit3 : BOOL;
bit4 : BOOL;
END_VAR

VAR_OUTPUT

result_out : INT;
END_VAR

BEGIN
result_out := 0;
result_out.x0 := bit0;
result_out.x1 := bit1;
result_out.x2 := bit2;
result_out.x3 := bit3;
result_out.x4 := bit4;
END_FUNCTION_BLOCK

You can go as yy1 suggested

Or you can use Old TrickVAR_INPUT in1 : BOOL; in2: BOOL; in3 : BOOL; in4:BOOL; in5 :BOOL; END_VAR VAR_OUTPUT value : INT; END_VAR BEGIN value := BOOL_TO_INT(in1) +(BOOL_TO_INT(in2)*2) +(BOOL_TO_INT(in3)*4)+(BOOL_TO_INT(in4)*8)+(BOOL_TO_INT(in5)*16);

Dear Globe,

I hope, that this will help you.

FUNCTION_BLOCK FB100 VAR_INPUT in1: BOOL; in2: BOOL; in3: BOOL; in4: BOOL; in5: BOOL; END_VAR VAR myInt: INT; tmp_bool AT myInt: ARRAY[0..15] OF BOOL; END_VAR BEGIN tmp_bool[8] := in1; tmp_bool[9] := in2; tmp_bool[10] := in3; tmp_bool[11] := in4; tmp_bool[12] := in5; tmp_bool[13] := false; tmp_bool[14] := false; tmp_bool[15] := false; tmp_bool[0] := false; tmp_bool[1] := false; tmp_bool[2] := false; tmp_bool[3] := false; tmp_bool[4] := false; tmp_bool[5] := false; tmp_bool[6] := false; tmp_bool[7] := false; END_FUNCTION_BLOCK

Best regards,

Manual

To be able to access a declared variable with a different data type, you can define views of the variable or of ranges within the variables using the "AT" keyword. A view is visible only locally in the block; it is not included in the interface. A view can be used like any other variable in the block. It inherits all the properties of the variable that it references; only the data type is new.

Example

The following example makes several views of one input parameter possible:

VAR_INPUT
Buffer : ARRAY[0..255] OF BYTE;
Frame1 AT Buffer : UDT100 ;
Frame2 AT Buffer : UDT200 ;
END_VAR

The calling block supplies the Buffer parameter, it does not see the names Frame1 and Frame2. The calling block now has three ways of interpreting the data, namely the array under the name buffer or with a different structure under Frame1 or Frame2.

Rules

• The declaration of a further view of a variable must be made following the declaration of the variable to which it points in the same declaration subsection.
• Initialization is not possible.

• The data type of the view must be compatible with the data type of the variable. The variable specifies the size of the memory area. The memory requirements of the view can be equal to this or smaller. The following rules for combining data types also apply:
