timeout

uint64_t rodbus_request_param_t::timeout

Response timeout for the request. It covers sending the request and receiving the response. A request that can't be sent in time fails with an I/O error, and the connection (or serial port) is closed and reopened, whatever the channel's limit on consecutive response timeouts. A response that doesn't arrive in time is a response timeout. On a serial port, the delay between frames is part of sending the request. A zero timeout is replaced by one millisecond; any other duration is used as given.

Note

The unit is milliseconds

unit_id

uint8_t rodbus_request_param_t::unit_id

Modbus address for the request.
