Remote Maintenance
The lineup now includes a wide variety of Smart Slaves with different numbers of control
points that contribute to production site servicing and repair.
Use production site information in a variety of applications,
such as maintenance and quality control.
OMRON's DRT2-series Smart Slaves do not just input and output ON/OFF signals. They collect a variety
of value-added information to help increase the rate of operation without changing the wiring for
existing DeviceNet networks. In particular, they allow the separation of control systems and
maintenance systems so that maintenance systems can be created independently of control systems.

Measuring
The Slave Unit represents
machine operating time and
operational changes as data,
enabling monitoring without
increasing the load between
controllers.
Counting
By counting the number of
ON/OFF operations and the
total operating time, the Slave
Unit can provide notification
when maintenance is required.

Collect a variety of data from maintenance systems without

All data can be converted to electronic format and,
by combining with an OMRON PLC (CS/CJ Series),
checked directly from Ethernet or the Internet to
allow remote maintenance.

Time
The peaks or valleys of temperature inputs that change in a regular pattern
are counted to predict when devices operating with severe temperature
swings are due for maintenance.
Short Startup
If it takes too long
to modify the
ladder program on
the Master when a
Temperature
Sensor is replaced:
Slaves internally
convert display values
to temperature input
values so the Controller
program no longer has
to be modified to
perform this task.
