Communication Adapters (D77D Series) — PROFIBUS Adapter
Product Description
The Cutler-Hammer
®
Intelligent Tech-
nologies (IT.) PROFIBUS Adapter
(D77D-PNA) from Eaton’s electrical
business has greatly increased the
functionality of Cutler-Hammer IT.
communicating products, allowing
monitoring and control for IT. I/O and
IT. motor control devices. The adapter
concentrates all data from these
devices into a single node.
The PROFIBUS Adapter supports not
only PROFIBUS but also Modbus
(ASCII and RTU) as a slave device. This
combination of the two physical layers
provides for ultimate functionality
when connecting to a control system.
This unique feature of the D77D-PNA
provides for deterministic control
using PROFIBUS along with the flexi-
bility to monitor and configure I/O
devices over Modbus. The Modbus
connection is a read-only connection
not allowing control of I/O devices
ensuring a single point of control.
To simplify the configuration of the
D77D-PNA, a simple auto-configure
button press sets the system up for
default operation. This automatically
configures the telegrams to the system
devices.
Application Description
In a typical PROFIBUS Adapter applica-
tion, the D77D-PNA connects directly
to PROFIBUS, and resides in a system
with IT. I/O and other communicating
motor controls. The data from these
IT. devices is assembled into input
and output telegrams before being
presented.
