6.2 Supported diagnostic messages
In the following the different diagnostic
messages are described in detail.
6.2.1 Extended diagnostics header
Byte 7 contains the length of the extended
diagnostics (including header itself).
6.2.2 Operating status
Diagnostic byte 9 contains certain parameters
(set in the system configuration).
Bit Definition 0 1
0 Direction of rotation CW CC
W
1 Class 2 functionality Off On
2 Diagnostic routine Off On
3 Scaling function Off On
6.2.3 Encoder type
Diagnostic byte 10 contains the encoder
version (singleturn or multiturn).
Byte 10 Definition
0 Singleturn encoder
1 Multiturn encoder
6.2.4 Singleturn resolution
Diagnostic bytes 11-14 contain the real
(physical) resolution per revolution of the
encoder.
6.2.5 Number of revolutions
Diagnostic bytes 15 and 16 contain the real
(physical) number of revolutions of the
encoder. Standard values are 1 for singeturn
and 65535 for multiturn devices.
6.2.6 Profile version
Diagnostic bytes 24 and 25 contain the profile
version of the encoder.

6.2.8 Operating time
The operating time of the encoder is not
supported set to FFFFFFFF hex
6.2.9 Zero offset
The zero offset is output in diagnostic bytes 32
to 35.
6.2.10 Programmed resolution
The programmed resolution per revolution is
output in diagnostic bytes 40 to 43. The value is
only valid if the scaling factor is based on the
parameter „resolution per revolution“ (cp.
5.1.3).
6.2.11 Programmed total resolution
The programmed, respectively calculated
total resolution is output in diagnostic bytes 44-
47.
6.2.12 Serial number
Diagnostic bytes 48-57 are intended for a serial
number.
