kitControl-NumericBitAnd
In value against the bit equivalent of its StatusNumeric mask slot value. It may be useful in cases where Boolean information
is mapped into integer values.
NumericBitAnd is available in the Util folder of the kitControl palette, along with the closely-related NumericBitOr and NumericBitXor components.
As an example, some manufacturers multiplex binary data into a single numerical point by converting the bits from hexadecimal to decimal format. To obtain the status of the individual binary data, the number must be converted back from decimal to hex format. Each digit of the hex number represents a particular binary state (0 = false, 1 = true). The NumericBitAnd object converts a StatusNumeric input to its hex value and compares it against the mask value. Any digits with a value of 1 in the mask and the input result in a corresponding value of 1 in the same digit of the output.
Figure 117. NumericBitAnd example
In this example:
- Input decimal 65553 converts to a hex value of 10011.
- Mask decimal 65536 converts to a hex value of 10000.
- The resulting hex value is 10000.
