ORQUAD, OROCT, ORHEXD – Logical sum of multiple signals

Block SymbolsLicensing group: STANDARD

Function Description
The ORQUAD, OROCT and ORHEXD blocks compute the logical sum of up to sixteen input signals U1, U2, …, U16. The signals listed in the nl parameter are negated prior to computing the logical sum.

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

If you have only two input signals, consider using the OR_ 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)
