Trait libmodbus_rs::ModbusTCPPI

pub trait ModbusTCPPI {
    fn new_tcp_pi(node: &str, service: &str) -> Result<Modbus, Error>;
    fn tcp_pi_accept(&mut self, socket: &mut i32) -> Result<i32, Error>;
    fn tcp_pi_listen(&mut self, num_connection: i32) -> Result<i32, Error>;
}

The TCP PI (Protocol Independent) backend implements a Modbus variant used for communications over TCP IPv4 and IPv6 networks. It does not require a checksum calculation as lower layer takes care of the same.

Contrary to the TCP IPv4 only backend, the TCP PI backend offers hostname resolution but it consumes about 1Kb of additional memory.

• Create a Modbus TCP context
  • new_tcp_pi()
