omron cp1e real time clock

[RAJNAIK]

hi all
i have used a real time clock to turn on a bit after 1 month.
the plc was off for this whole month and when i turned on the plc after a month,
the bit which has to be ON according to real time clock didn't turn ON.
plc has a battery also.
what might be the reason for this.

1) Can you upload the code?

2) What is the battery voltage now?
