Function operation:
Function performs the operation of a multi-input OR logic gate. The following is the truth table for the OR function for the two input signals X and Y. When creating a function block, specify the number of function inputs (in the range 2 to 10).

According to the presented truth table, the function returns high state on the OUT output only when at least one of its IN inputs is high. When a low state appears on each of the IN inputs, the function returns a low state.
