9.4. Function blocks in the "OPERATOR" window
All inputs on these operators can be inverted (logical NOT). To invert, click the input that is to be inverted using the right
mouse button. A small circle then appears on the inverted input. To clear the inversion, simply click the same input again.
Important!
The maximum permissible number of function blocks is 64.
9.4.1. Logical operators
9.4.1.1. AND
The logical operator AND produces an output of "1" (TRUE) if all inputs
are "1" (TRUE).
