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.

Work

1

Use production site information in a variety of applications,

such as maintenance and quality control.

The Slave can hold comments, allowing

quick identification of fault locations and

faulty devices.

The Slave Unit represents

machine operating time and

operational changes as data,

enabling monitoring without

increasing the load between

controllers.

By counting the number of

ON/OFF operations and the

total operating time, the Slave

Unit can provide notification

when maintenance is required.

cylinder 23A in

inspection line A!

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.

Information monitoring for

each Slave

Collect a variety of data from maintenance systems without

influencing control systems and productivity.

Slaves internally

convert display values

to be modified to

perform this task.

The operating time of a preset temperature range is counted in 1-s units.

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.
