SDD16 Description  

The  SDD16  driver  allows  the  FieldServer  to  transfer  data  to  and  from  devices  over  RS-485 
using SDD16 protocol.  The FieldServer can only emulate a Client.  
 
The  SDD16  driver  is  used  to  communicate  with  a  digital  I/O  module  model  485SDD16.    The 
current  driver  only  supports  reading  the  status  of  all  sixteen  digital  input  lines.    The  SDD16 
driver  in  conjunction  with  the  485SDD16  module  allows  the  FieldServer  to  sense  external 
On/Off conditions and to control a variety of devices. 
 
The SDD16 driver makes use of the data complement mode feature of the 485SDD16 module.  
In data complement mode the driver and module communicates with double the amount of data 
bytes to enable better error detection in noisy electrical environments.
