One of the following was detected at pow-
er ON.
• Built-in capacitor discharged
• Battery not mounted
• Mounted battery discharged

• In case of clock oscillator stopping
T
ime measurement starts from January 1st, 1970.
• In case of low battery voltage
T
ime measurement continues.
Error detec-
tion
The following error is detect-
ed.
• Low Battery Voltage
• Real-T
ime Clock Stopped
No error is detected.
One of the following was detected after
power ON.
• Battery was removed
• Mounted battery discharged
Clock data Time measurement continues.
Error detec-
tion
The following error is detect-
ed.
• Low Battery Voltage
No error is detected.
When you mount the battery, set the Battery-related error detection to Use.
The measurement of clock data starts from January 1st, 1970 if the clock oscillator stops. If this oc-
curs, readjust the CPU Unit’
s clock data to the current time.
In order to use the clock data for programming, you need to use system-defined variables to read the
presence or absence of the Low Battery V
oltage and Real-Time Clock Stopped errors and confirm that
the clock data is normal.
Refer to the Sysmac Studio Version 1 Operation Manual (Cat. No. W504) for battery-related error de-
tection and clock data settings.
