Flexibility is
provided in the
combinations for the
number of I/O points. It is
possible to mix a variety
of Units, such as Input
Units and Output Units as
well as Analog Units
and Digital Units.
Wiring is easy. Simply
insert the ferrule.
(No screwdriver is
required.)
A DeviceNet
Communications Unit
is featured in the
product lineup.
Parameters can be
set and maintenance
performed for
Communications Units or
SmartSlice I/O Units.
Up to 64 SmartSlice I/O
Units can be connected
to one Communications
Unit.
Blocks can be divided
by using Turnback
Units and Turnback
Cables if there is not
sufficient width in the
control panel.
Remote I/O Communications
Data from the Slice I/O Units
connected to the
Communications Unit is
collected by the
Communications Unit, then
data is exchanged in a single
transmission with the Master
Unit.

DeviceNet Communications Unit
GRT1-DRT
DeviceNet-compliant Interface Unit with up to 1,024 I/O Points at
One Node
• Connect up to 64 SmartSlice I/O Units.
• Consolidate a large capacity of I/O points into one Slave (up to
1,024 I/O points).
• Save space by configuring different I/O types using one Slave Unit.
• Easily get the system started simply by setting the node
addresses.
• Replace SmartSlice I/O Units online while maintaining
communications. This helps minimize equipment downtime.
• Smart functions for monitoring equipment operating status. This
helps improve preventive maintenance and the utilization rate.
• Registering SmartSlice I/O for planned future expansion
decreases design work when changes are made. (Supported for
unit version 2.0 or higher.)
