A function block used for bitwise logical multiplication (conjunction). Sets the output value to be the result of logical multiplication, that is applied to each pair of bits located at the same position in the binary representation of input values.
In other words, the resulting bit of the output value is equal to:
- "1" if both respective bits of the input values are equal to "1";
- "0" if at least one bit of the pair is "0".
For example:
| Value X | = | 27 | = | 0x001B | = | 0b0000000000011011 |
| Value Y | = | 58 | = | 0x003A | = | 0b0000000000111010 |
| Result | = | 26 | = | 0x001A | = | 0b0000000000011010 |
Features
Operation 'Bitwise AND' is used to mask — to select specific bits or fields from several bits of a binary number.
