Battery-related Error Detection and Clock Data Settings
Because the CPU Unit is shipped with the battery not mounted, the
Battery-related error detection
is
set to
Do not use
by default.
The behavior of the CPU Unit when a battery-related error is detected depends on whether battery er-
ror detection is used or not used as shown in the table below.
When the battery is not mounted, you can set the
Battery-related error detection
to
Do not use
to
suppress battery errors.
When the battery is mounted, however, you can set the
Battery-related error detection
to
Use
to de-
tect battery errors.

One of the following was detected
at power ON.
•
Built-in capacitor discharged
•
Battery not mounted
•
Mounted battery discharged
Clock data
•
In case of clock oscillator stopping
Time measurement starts from January 1st, 1970.
•
In case of low battery voltage
Time measurement continues.
Error detection
No error is detected.
The following error is detected.
•
Low Battery Voltage
•
Real-Time Clock Stopped
One of the following was detected
after power ON.
•
Battery was removed
•
Mounted battery discharged
Clock data
Time measurement continues.
Error detection
No error is detected.
The following error is detected.
•
Low Battery Voltage
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 Voltage 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.
