System Overview
Product Description
The SmartWire-DT
®
In-Panel
and On-Machine wiring
system uses a single green
cable inside a machine
control cabinet and across
the machine itself to connect
motor starters, variable
frequency drives, soft starters,
pushbuttons, sensors,
pneumatic and hydraulic
valves, stacklights and other
indicator lights.
Inside the machine control
cabinet the continuous
SmartWire-DT green cable is
flat. The flat cable connects
directly to in-panel motor
starters, variable frequency
drives, soft starters,
panel-mounted pushbutton
actuators, stacklights and
other indicator lights. It
eliminates the need for
most of the conventional
point-to-point control wiring
done in a traditionally wired
control panel—and even
integrates 24 Vdc control
power for contactor coils on
the single SmartWire-DT
cable. The start of the
SmartWire-DT system is
either an Eaton PLC or a
combination HMI/PLC with
SmartWire-DT embedded or
a simple gateway.
These SmartWire-DT
gateways establish the
connection between a
SmartWire-DT system and
standard programmable logic
controller (PLC) fieldbuses,
such as EtherNet/IP, Modbus
TCP, EtherCAT, PROFINET,
POWERLINK, PROFIBUS-DP
and CANopen. The gateway
works without any
conventional PLC I/O required
because SmartWire-DT
directly integrates the
input/output (I/O) level in
the switching devices.
Inside the control cabinet,
typical faults such as loose
connections and miswired
terminations are eliminated
using the flat cable and
the specialized connectors.
Outside the cabinet on the
machine, the SmartWire-DT
digital machine mount I/O
modules connect using
industry standard keyed M12
connectors to eliminate the
possibility of miswiring.
Further, dramatic wiring
reductions are possible given
the single SmartWire-DT
cable connection that brings
24 Vdc power to and carries
signals to and from devices.
Each SmartWire-DT machine
mount I/O module has
diagnostic LEDs built in,
reducing commissioning
time and troubleshooting in
the field.
Nodes on the SmartWire-DT
network both inside and
outside the main control
cabinet are automatically
assigned addresses by the
gateway or the HMI/PLC
device with the simple push
of a button—assigning
addresses in the order that
the nodes are connected.
The system employs time
monitoring and a watchdog
timeout using the established
target configuration as a
reference—safely monitoring
the integrity of the control
scheme. SmartWire-DT has
a maximum network length
of 2000 feet and can connect
up to 99 nodes per gateway.
A software program called
SWD-Assist enables the
layout, planning and system
configuration of a
SmartWire-DT network.
