11.2.6 Number of revolutions
The physical number of the distinguishable revolutions per encoder can be
enquired via the two diagnostic bytes 15 and 16� The standard values for
singleturn is 1 and 4096 (or 16384) for multiturn�
11.2.7 Operating time alarm
The warning message for exceeding the operating time is indicated in bit 4 of
diagnostic byte 21� The bit is set after 10 5 hours�
11.2.8 Profile version
The profile version of the encoder is stored in the diagnostic bytes 24 and 25�

11.2.10 Operating time
The operating time of the device is recorded in the diagnostic bytes 28���31� While
the supply voltage is applied, the value (Operating time) is stored again in the
encoder in steps of 0�1 every 6 minutes�
11.2.11 Zero point shift
The zero point shift is provided in the diagnostic bytes 32���35�
11.2.12 Configured resolution
The configured resolution per revolution of the encoder is stored in the diagnostic
bytes 40���43� This value is only valid if the gearbox factor was calculated in the
parameter mask via the setting [Resolution per revolution]�
11.2.13 Configured total resolution
The configured or calculated total resolution is stored in diagnostic bytes 44���47�
