Transmission period and/or transmission rate estimating method for use during data communication, involves estimating period and/or rate based on transmitting time point and receiving time point after receiving one of telegram

摘要

The method involves sending a transmitting time point (ts(i - 1)) of a telegram (T(i - 1)) which is transmitted before a transmitting time point (ts(i)) to a receiver (E). The receiver estimates a transmission period and/or a transmission rate based on the time point (ts(i - 1)) and a receiving time point (te(i)) after receiving a telegram (T(i) that is received at the time point (te(i)) and transmitted to the time point (ts(i)). An independent claim is also included for a communication device for an automation device with a transmitter and a receiver.
