4.2.2 Extended diagnosis
In addition to the standard DP diagnostic message, the encoder also provides an
extended diagnostic message according to the PNO encoder profile. This message
varies in length depending on the chosen nominal configuration. In the configurations
designated "TR mode", the diagnostic message corresponds to PNO Class 2.
The following pages provide a general overview of the available diagnostic
information. Which individual options your encoder actually supports can be read out
from the device itself.
