Smart Slaves DRT2 Series
In addition to the standard control functions, the DRT2-series Smart
Slaves can collect a wide variety of manufacturing plant information and
serve as key components in maintenance and quality control systems.

The DRT2-series Smart Slaves do not just handle the ON/OFF
signals of I/O devices; they can accumulate a variety of information
to improve the operating efficiency of the equipment. A maintenance
system can be constructed that is separate from the control system.
The side-by-side control system/maintenance system configuration
allows the existing DeviceNet wiring to be used, reduces the
customer’s equipment setup time, reduces the downtime in the event
of a problem, and provides preventative maintenance capabilities.

Configurator (Ver. 2.20 or Later) Maintenance Window
Various equipment information can be monitored from the following Configurator window (Ver. 2.20 or later) through DRT2-series Smart Slaves.
● Maintenance Mode Window
● Individual Slave’s Maintenance Information Window
A DRT2-series Smart Slave’s maintenance information window can
be displayed by double-clicking the Slave’s icon if an alarm indicator
appears next to the Slave’s icon.
Depending on the maintenance information that has been generated,
more details can be viewed by clicking the OUT tab, IN tab, or
Operation Time tab.
Maintenance information refresh icon
Reads the current maintenance information.
Alarm indicator icon
Maintenance information window
Maintenance information
Displays current maintenance information.
A Smart Slave’s maintenance counters can be
stored in flash memory. The “number of contact
operations” count is normally stored every 6
minutes, so up to 6 minutes of data may be lost
depending on when the power is turned OFF.
Refreshes the current
Slave’s maintenance
information
An alarm indicator will
appear wherever the
present value exceeds
the monitor value, so
locations requiring
maintenance can be
identified immediately.
Depending on the
maintenance information
that has been generated,
more details can be
viewed by clicking the
OUT tab, IN tab, or
Operation Time tab.
