BKAND​


The BKAND instruction performs a logical AND on n number of WORD data registers starting at S1 and n number of data registers starting at S2 and saves the result in an assigned WORD data register, D.

Ladder Diagram Example​


When the contact, M6.0, is powered ON (1), logical AND operations are performed on 3 WORD data registers, D0, D1, and D2, with another 3 WORD data registers, D4, D5, and D6.
The results of the logical AND operations are saved in 3 WORD data registers, D8, D9, and D10.

The below image shows the direct logical AND operations for each data register.


BKANDP​


The BKANDP one-shot instruction performs a logical AND on n number of WORD data registers starting at S1 and n number of data registers starting at S2 and saves the result in an assigned WORD data register, D.
Every time this instruction energizes, it executes only once.

Ladder Diagram Example​


When the contact, M7.0, is powered ON (1), logical AND operations are performed on 4 WORD data registers, D10, D11, D12, and D13, with another 4 WORD data registers, D15, D16, D17, and D18.
The results of the logical AND operations are saved in 4 WORD data registers, D20, D21, D22, and D23.
