Can FX1N-BAT be installed on FX1S?

[Sergei Troizky 26]

The FX1S features the same connector and mounting place as FX1N, but I have not found any document about possibility to install the FX1N-BAT battery on FX1S. Does anybody know about such document? Or did anybody succesfully use such combination?

if i remember correctly FX1S doesn't need battery at all. it has flash...

btw. What is FX1N-BAT?? => FX1N & FX1S: internal backup capasitor, 10 days, 30 minutes recharge time. I think memory is EEPROM (10000writes). According to manual some data is saved only when CPU powered more than 5 minutes (FX1S). Real time clock is backed up by that capasitor. Tmu

The FX1N-BAT is a module that plugs into the memory card area and extends the internal capacitor backup to something like 200 days. The program is stored on EEPROM, so it never gets lost. But this extends the memory backup for the RAM section of the PLC memory.
