modbus_protocol #
Modbus is a data communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs).
Modbus has become a de facto standard communication protocol and is now a commonly available means of connecting industrial electronic devices.
Usage:
// use lib: byte_util: ^1.1.0
void testModbusProtocol() {
final bytes = [1, 2, 3, 4, 5, 6, 7, 0xff, 0xa1, 0xdd];
final modbus = ModbusProtocol(bytes);
final crc = modbus.crc;
// got:[175, 61]
print(crc.word);
}
