16 Smart Slaves DRT2 Series
Smart Slave Functions
● Network Power Voltage Monitor
The present, bottom, and peak values of the Network power voltage
can be recorded in the Slave. Also, the monitor voltage can be set
using the CX-Integrator to maintain the monitor voltage in the slave
(default setting: 14 V), and a Status Area in the Unit will turn ON if
the voltage falls below the monitor voltage.
● Unit Conduction Time Monitor
The total ON time of the Slave's internal circuit power can be
calculated and recorded. (The CX-Integrator or explicit messages
can be used to read the information.)
Also, the monitor value can be maintained in the Slave, and a Status
Area will turn ON in the Unit when the total time reaches the set
value.
● Unit Comment Function
The user can assign and record a name or comment for every Unit
(up to 32 characters).
● Connected Device Comment Function
The user can assign a name for each of the Unit's I/O contacts (up to
32 characters) and record it in the Unit. The connected device can be
checked for each I/O contact, allowing faulty devices to be identified
during remote maintenance.
● Communication Error History Monitor
The error status information (communications error code and
communications power voltage when the error occurred) for the last
four communications errors that occurred can be recorded in the
Slave.
● Last Maintenance Date
This function enables writing to the Unit the date on which
maintenance was last performed. This means that the timing for
future maintenance can be judged more easily.
● Contact Operation Count Monitor Function
The Contact Operation Counter is used to count the number of times
each input or output contact changes from OFF to ON (maximum
sampling cycle: 50 Hz) and record the total value calculated in the
slave. (The CX-Integrator or explicit messages can be used to read
the information.)
The monitor value can be set in the slave, and when the set number
of operations is reached, a bit in the Status Area in the Unit will be
turned ON. (The CX-Integrator or explicit messages can be used to
read the details of the notification.)
• Counted operations: 0 to 4,294,967,295 operations
(Stored data: 0000 0000 to FFFF FFFF hex)
• Counting unit: One operation
Note 1: The Contact Operation Counter and Total ON Time Monitor cannot be used
at the same time for the same contact. Select the function to be used under
the Detection Mode heading.
Note 2: The Contact Operation Counter will operate only when the I/O power is ON.
