Features
The E5AR-DRT and E5ER-DRT (E5AR/ER-DRT) are Digital Controllers that
use DeviceNet for communications.
1-1-1
Outline
The E5AR/ER-DRT Digital Controllers are slaves that connect to the
DeviceNet open field network. DeviceNet communications enable controlling
operation, collecting measurement data, and writing settings from a host com-
puter or PLC. The E5AR/ER-DRT support both remote I/O communications
and explicit message communications.
Remote I/O communications allow the master and the E5AR/ER-DRT to auto-
matically share data via high-speed I/O without any special programming of
the master. Remote I/O communications are particularly suited to operation
control, error warnings, and monitoring applications.
Explicit messages use a communications protocol for sending commands and
receiving responses. The main application for explicit message communica-
tions is for changing E5AR/ER-DRT settings data.

Communications
The master and E5AR/ER-DRT Digital Controllers can share I/O by using
remote I/O communications. Data in the E5AR/ER-DRT Digital Controllers,
such as process values (PVs) and set points (SPs), can be allocated for com-
munications with the master to enable sending and receiving the allocated
data via remote I/O communications without requiring special programming.
