ANDQUAD, ANDOCT, ANDHEXD – Logical product of multiple signals

Block SymbolsLicensing group: STANDARD

Function Description
The ANDQUAD, ANDOCT and ANDHEXD blocks compute the logical product of up to sixteen input signals U1, U2, …, U16. The signals listed in the nl parameter are negated prior to computing the logical product.

For an empty nl parameter a simple logical product $Y = U1 \land U2 \land U3 \land U4 \land U5 \land U6 \land U7 \land U8$ is computed. For e.g. nl=1,3..5, the logical function is $Y = \neg U1 \land U2 \land \neg U3 \land \neg U4 \land \neg U5 \land U6 \land \dots U16$ .

If you have less than 4/8/16 signals, use the nl parameter to handle the unconnected inputs. If you have only two input signals, consider using the AND_ block.

Inputs

U1..U16	Logical inputs of the block	Bool

Outputs

Y	Result of the logical operation	Bool
NY	Boolean complementation of Y	Bool

Parameter

nl	List of signals to negate. The format of the list is e.g. 1,3..5,8. Third-party programs (Simulink, OPC clients etc.) work with an integer number, which is a binary mask, i.e. 157 (binary 10011101) in the mentioned case.	Long (I32)
