6.1 Overview
In the "DDLM_Slave_Diag" operating mode, diagnostic data is transferred from the
rotary encoder to the master on request. The number of diagnostic bytes is 57.
Exception: Reduced diagnostics (see section 5.1.5). Output of diagnostic data is
based on the specifications of the PROFIBUS standard (Octets 1 ... 6) or on the
encoder profile (starting at Octet 7).
