3.2.2.5 Working Counter
In 1-Buffer mode (please refer to 2.3.2.2) the master may check the working counter value. This value will be
incremented by +1 if the encoder internal application controller was able to successfully write process data
into the ECAT controller. This mechanism enables the master to detect encoder freezing in a PDO transmis-
sion synchronous manner.
