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, that is, the circuit program converts a logical "1"
at the input into a logical "0"; a logical "0" it converts into a logical "1". See the programming
example in topic "Circuit program input (Page 86)".
The table also specifies whether the relevant function can be set retentive (Rem). The
following SFs are available:
