modbus_set_response_timeout(ctx,&t); libmodbus中对 modbus_set_response_timeout的定义如下: Themodbus_set_response_timeout()function shall set the timeout interval used to wait for a response. If the waiting before receiving the response is longer than the given timeout, an error will be ...
instead all bytes are sent as fast as possible and a response or an indication is considered complete when all expected characters have been received. This implementation offers very fast communication but you must take care to set a response timeout of slaves less than response timeout of maste...
