NOTE 
Should the 63-byte diagnostic not work properly using STEP7 
software we suggest setting the 16-byte diagnostic. 
If diagnostic information is not used, it is recommended to set 16-
byte diagnostic (see “5.1.3 Encoders configuration parameters” 
section). 
See section “6.7 DDLM_Slave_Diag” for a complete list and meaning 
of each diagnostic byte.
