Three practical calculators on one page: register bit masks, BIN/OCT/DEC/HEX conversion and engineering range scaling for 0-10 V, 4-20 mA, ADC values and percent.
Bit calculator
Build a value from bit cells or decode BYTE, WORD, DWORD, signed types and REAL into bits.
WORD: 16 bits, range 0...65535
Bit calculator for Modbus, PLC and registers
Use it for flags, control masks, status words, holding registers, input registers and IEEE-754 Float32 checks.
