Parses one frame up to 4096 bytes without contacting equipment
Parses one frame up to 4096 bytes without contacting equipment. Modbus TCP includes MBAP fields and length validation; RTU includes CRC-16 validation; common function codes expose addresses, quantities, register values, bits and exceptions. OPC UA TCP exposes message/chunk headers and HEL/ACK negotiation fields. Register scaling, byte order beyond the protocol, device maps and vendor semantics are not guessed.
