NADO

Because of the

 NDRA91

P is a linear encoder for measuring absolute distances

the parameters "code sequence", "scaling function control", "measuring units 
per revolution" and "measuring range in measuring units" are ignored. 

Diag Common 

The  (general)  diagnosis  data  correspond  entirely  to  the  profile  standard,  and 
will  be  updated  with  every  Profibus-Diagnosis-Request.  The  Common  Diag-
data  require  the  class  2  functionality  and  the  Commissioning  diagnostics 
function. In the event of errors (Enn), an alarm is issued as extended diagnosis 
which  contains  all  diagnosis  data.  To  see  the  current  temperature  and 
operating time, the diagnosis interval has to be set ≠ 0. A diagnostic Interval of 
100 leads to a data update every 10 sec. 

Please  observe  that  the  laser  has  to  capture  and  transmit  a value  in  the  DF 
modes, i.e. temperatures are only transferred if values are captured. 

Diag Alarm 

Error  messages  of  the  laser  are  sent  as unique  Ext. Diag.  The  alarms  are  not 
saved. 

E98 shows problems with the internal communication. If errors occur, they are 
reported as Ext. Diag and then please try to activate the laser again.
