how can i introduce input and output via the SCL

[OMU]

You can use them directly in your source

Example:

Code: Select all

If  I6.2 then Q2.2
End_if

If you wish to create an FB or FC with in- and outputs, then you have to
define them as variables, example:

Code: Select all

VAR_INPUT
    
FAST_B      :  INT;  // (can also be bool, dint etc.)
SLOW_B     :  INT; 
STEP_B      :  INT;

END_VAR

I hope, this will answer your question.
