7.2.2.18 Manufacturer's diagnoses

The measuring system does not support further manufacturer's diagnoses.
Important information
According to the PNO profile for encoders, if an internal error in the station status is
identified, the encoder must set the bits "ext.Diag" (extended diagnosis information
available) and "Stat.Diag" (static error) . This means that in the case of an error, no
more position data is output and is removed from the PROFIBUS master from the
process image until the error bits are reset. Acknowledgement of the error by the user
via the PROFIBUS is therefore not possible.
This function is only guaranteed if the "commissioning diagnostic" function is
activated.
