THE ENGINEER’S WORKBENCH
Work it out. See why.
The conversion is the easy part. Know which value to enter, what the answer means, and what to check on the machine.

Number & Bit ConverterConvert binary, decimal, hexadecimal and octal. Flip bits, inspect nibbles and compare signed integers through 64 bits.Data Size & Transfer TimeConvert bits, bytes, MB and MiB, then estimate ideal transfer time from a link rate in megabits per second.Float & Register DecoderDecode IEEE-754 float32 bytes or encode a REAL value. Compare four byte orders, two register values and the underlying bits.Engineering Unit ConverterConvert length, pressure, temperature, flow, torque and other engineering units with explicit dimensions and conversion factors.Analog Signal ScalingScale 4–20 mA, voltage or raw PLC counts into engineering units. Reverse the calculation and inspect unclamped overrange.Current Loop Voltage BudgetCheck a two-wire current loop’s supply, transmitter requirement, receiver burden and cable resistance at the chosen current.Modbus Address TranslatorTranslate zero-based offsets, one-based indexes and conventional 5- or 6-digit Modbus references without off-by-one errors.Modbus RTU CRC CheckerAppend or verify CRC-16/MODBUS from hexadecimal bytes. See the expected low-byte-first trailer and corrected frame.IPv4 Subnet CalculatorFind the mask, network, broadcast and host range for an IPv4 CIDR address. Check a PLC or HMI peer against that subnet.Encoder Resolution CalculatorConvert encoder pulses and quadrature decoding into counts, travel resolution and frequency at the counter input.Gearbox & Conveyor SpeedCalculate output RPM and belt speed from motor speed, an input-to-output gear ratio and roller diameter.PLC Scan & Pulse TimingExplore whether a cyclic PLC task samples a pulse and whether a non-retentive on-delay timer reaches its preset.
