IT. Connect
Communication Adapters (D77D Series) — PROFIBUS Adapter
Cat. No. D77D-PNA
Product Description
The Cutler-Hammer Intelligent
Technologies (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. motor
control devices. The adapter concen-
trates 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 communicating motor controls.
The data from these IT. devices is
assembled into input and output
telegrams before being presented.
