3  Device description 

 

3.1  General information 

 

Various  mechanical  variants  of  the  WDGA-series  encoders  with  EtherNet/IP  are 
available. The required variant is determined by the need for a bus cover, the flange 
design  and  the  shaft  type  (solid  or  hollow).  The  size  is  specified  as  58  mm  by  the 
diameter at the flange. The following figure shows examples of WDGA-series encoders 
with EtherNet/IP. 

 

Figure 3.1: WDGA with EtherNet/IP bus cover 

The  solid  or  hollow  shaft  is  connected  to  the  rotating  component  whose  angular 
position  or  rotational  speed  is  to  be  measured.  Cable  or  plug  outlets  create  the 
interface for connection to the EtherNet/IP network. The status LEDs mounted in the 
cover signal the various encoder states during operation. They assist with configuration 
of  the  encoder  and  troubleshooting  in  the  field.  The  flange  holes  or  supplied  spring 
sheets are used for attachment to the machine and during the respective application. 

 

3.2  EtherNet/IP 

 

EtherNet/IP  is  a  real-time  Ethernet,  which  was  developed  by  Allen-Bradley  and  is 
managed  today  as  an  open  standard  by  the  Open  DeviceNet  Vendor  Association 
(ODVA). It is based on the CIP standard (Common Industrial Protocol) and is used for 
the transmission of cyclic I/O data, as well as acyclic parameter data.  

EtherNet/IP  offers  different  topologies,  but  mostly  an  active  star  or  ring  topology  is 
used. With the ring topology, the DLR ("Device Level Ring") can be used to prevent a 
total failure in the network due to a cable break, for example. 

 

3.3  WDGA 

— basic principles 

 
The following sections describe the basic functions of an absolute encoder.
