4.4 Special functions list – SF
When you create your circuit program in LOGO!, you find
the special function blocks in the SF list.
You can invert the inputs of SFs individually, i.e. the circuit
program converts a logical “1” at the input into a logical “0”;
a logical “0” it converts into a logical “1”. An example of the
program code found in Chapter 3.7.3.
The table also specifies whether the relevant function can
be set retentivity (Rem). The following SFs are available:
