3.6 Clock/Calendar Function

The clock/calendar function can be used if the backup battery (see page 95) is installed in the
FPΣ. There are no default clock/calendar settings, so the programming tool or another means
must be used to specify these values.

3.6.1 Memory Area for Clock/Calendar Function

With the clock/calendar function, clock and calendar data stored in special data registers
DT90053 to DT90057 can be read and used in sequence programs. To access special data
registers and special internal relays, use the PLC-independent system variables.

3.6.2 Settings for Clock/Calendar Function

The clock/calendar values are backed up using a battery. Therefore, the clock/calendar
function cannot be used unless a battery has been installed.
There are no default clock/calendar settings, so the programming tool or another means must
be used to specify these values. There are two ways to set the clock/calendar function:
Using the programming software
1. Online → Online Mode
2. Monitor → Display Special Registers → Calendar Functions
3. Enter the desired date and time values
