Product Description
The Cutler-Hammer Intelligent
Technologies (IT). Ethernet Modbus
Adapter (D77D-EMA) 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
concentrates all data from these
devices into a single Modbus node.
The Modbus Adapter supports not
only Modbus TCP but also Modbus
serial (ASCII and RTU) as a slave
device. This combination of the two
physical layers provides for ultimate
functionality when connecting to a
Modbus system. A unique attribute
of the D77D-EMA is that it supports
Modbus serial Pass-Through. In this
mode a customer can connect Modbus
serial devices to one of the channels
and monitor and control them over
Modbus TCP.
To simplify the configuration of the
D77D-EMA, a simple auto-configure
button press sets the system up for
default operation. This automatically
configures the Modbus registers to the
I/O system devices.
Application Description
In a typical Modbus Adapter applica-
tion, the D77D-EMA connects directly
to Modbus, and resides in a system
with communicating motor controls.
The data from these IT. devices is
assembled into input and output
registers before being presented
to Modbus.
