6 EtherNet/IP
The product supports all measure, calibrate, configure and diagnose features of the
DataStick via EtherNet/IP.
EtherNet/IP™ is a low-cost open industrial network that links industrial devices (such as
limit switches, photoelectric sensors and motor starters) to machine controllers over
Ethernet.
This section describes the EtherNet/IP Network Object Model which completely
describes the interface from the EtherNet/IP network point of view. It also describes the
unit configuration, unit initialization and the EtherNet/IP Network Model.
6.1 Electronic Data Sheet (EDS)
The EtherNet/IP Electronic Data Sheet (EDS) is called 282EEIP.eds and can be found on
the Ethernet Files CD that is supplied with the Ethernet product. Be sure to register the
EDS file with the configuration tool that you will be using.
