Gather and Use Information for Effective
Preventive Maintenance
Get more useful data for preventive maintenance
when you build cost-effective parallel information
systems for control and maintenance using Omron’s
smart remote I/O terminals. These remote I/O
terminals include economical expansion units that let
you design a monitoring system for maintenance
information.
Smart Measuring and Smart Counting
These two functions take advantage of the intelligent
capabilities of DeviceNet. In Smart Measuring, the
remote I/O terminals convert machine operating time
and operational changes to data enabling monitoring
without increasing the load between controllers.
Smart Counting keeps track of the ON/OFF
operations and total operating time so preventive
maintenance can be scheduled based on service life
estimates. The operation counter and operating time
monitor functions cannot be used simultaneously.
What Device is Reporting Problems?
These slave units can hold comments such as device
number, type and location to shorten troubleshooting
by identifying fault locations and faulty devices. They
can also be used to monitor network communication
errors.
■ 16-point input and output terminals, NPN or PNP
models with DeviceNet connection
■ Expansion terminals available in 8-point and 16-
point units
■ Input filter function eliminates noise from contact
bounce and, using OFF response time, can capture
pulses shorter than the communications time
■ Sensor inrush current protection delays accepting
input for 100 ms after input power turns on
■ Inputs powered by the network power supply
■ Compact size saves space in control panels
■ Network Power Monitor function
