LRC Knowledge
LRC (Longitudinal Redundancy Check) is a data verification method that calculates the two's complement of the sum of all bytes.
Features
- Simple calculation: Addition and two's complement
- Better error detection than simple checksum
- Commonly used in MODBUS ASCII protocol
- Can detect odd number of bit errors
Applications
- MODBUS ASCII communication
- Industrial protocols
- Serial data transmission
- Message integrity verification
- Terminal communication
Security Recommendations
- Not suitable for data security purposes
- Consider using CRC for better error detection
- Use with other verification methods for critical data
- Be aware of its limitations in error detection
