What Are Smart Functions?
■ Smart Functions
● Network Power Voltage Monitor
The Network Power Voltage Monitor function stores the present
value, minimum value, and maximum value of the network power
voltage in the Slave Unit memory. If a monitor voltage is set using
the CX-Integrator, the monitor voltage is stored in the Slave Unit
memory. (The default is 14 V.) If the voltage drops below the
monitor voltage, a flag in a status area in the Slave Unit will turn
ON to notify the Master Unit.
● Unit Conduction Time Monitor
The cumulative time that power is ON to the Slave Unit's internal
circuits can be stored in the Slave Unit memory. (This data can
be read using the CX-Integrator or using explicit messages.)
The monitor value is also stored in the Slave Unit memory so
once the total time reaches the monitor value, a flag in a status
area in the Slave Unit turns ON to notify the Master Unit.
● Naming Units
The user can set any name for each Unit (up to 32 characters) as
a comment. The name is stored in the Slave Unit memory. The
CX-Integrator or explicit messages can be used to read/write the
name (i.e., the comment).
● Naming Connected Devices
The user can set any name for each I/O contact in the Unit (up to
32 characters).
These names are stored in the Slave Unit memory. Connected
devices can be checked for each I/O contact, which is useful for
remote maintenance and other applications where, for example,
devices with errors need to be identified.

● Communications Error History Monitor
The previous four error history records (communications error
codes and the power voltage when the error occurred) can be
stored in the Slave Unit memory.
● Last Maintenance Date
This function can be used to write the date maintenance was last
performed in the Slave Unit memory. This makes it easier to
decide when the next maintenance should be performed next.
● Contact Operation Monitor (Digital I/O Slave, Bit Slave
The number of times each input contact or output contact is
turned ON can be counted (resolution: 50 Hz max.) and stored in
Slave Unit memory. (This data can be read using the CX-Integra-
tor or using explicit messages.)
A monitor value can also be stored in the Slave Unit memory so
once the number of contact operations reaches the monitor
value, a flag in a status area in the Slave Unit turns ON to notify
the Master Unit. The notification details can be read using the
CX-Integrator or using explicit messages.
