4-3-5 Total ON Time Monitor
Function Overview The total ON time for each I/O contact can be calculated (unit: s) and
recorded in the Slave. (The Configurator 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 opera-
tions is reached, the Connected Component Maintenance Flag in the Status
Area is turned ON. (The Configurator or explicit messages can be used to
read the status of the Connected Component Maintenance Flag.)
• Measured time: 0 to 4294967295 s (stored data: 00000000 to FFFFFFFF
Hex)
• Measuring unit: s
Note 1. The Total ON Time Monitor and Contact Operation Counter cannot be
used at the same time for a single contact. Select the function to be used
under the Detection Mode heading.
2. The Total ON Time Monitor operates when the I/O power is ON only.
3. The Total ON Time Monitor checks approximately every second whether
the connected devices are ON.
If the total ON time is calculated for ON times of less than a second, the
measurement may not be accurate.
