1.4 About the Communications Function for
the CompoBus/D (DeviceNet) Network
The E5EK-DRT operates as a slave on the CompoBus/D (DeviceNet)
network. Items (parameters, operation instructions and statuses) that
have been assigned as communication data on the E5EK-DRT can be
uploaded and downloaded between masters and slaves.
16 read and write operations can be assigned as communication data,
and can be assigned.

As the data structure is flexible like this, communications is possible
using numerous parameter configurations, and the number of parame-
ters can be limited to increase processing speed.
For details on the type of communication data and how to assign data,
see Chapter 6 Using CompoBus/D (DeviceNet).
For details on cable connections on the CompoBus/D (DeviceNet) net-
work, see Chapter 2 Preparations, 2.3 Wiring Terminals (page 2-7).
