I think the time is in the hard drive .

so is it possible to be modified or not ?

No . You cannot change it. It is a new feature made by FANUC and it is not in the Ladder. Usually this lock message is set by the Machine tool builder (MTB). You must ask them to unlock.

as I said before, I am not trying to unlock the message, I am trying to bring back the date to a date earlier than the lock date so as to make the machine will become operational again with the same locking conditions set by the machine tool builder
so my question is... am I able to modify the date in this case or not ?

Back up your ladder and go into the BOOT mode and delete the ladder file, then your controller will BOOT without the ladder so IF the ladder is doing it you will be able to change the date. IF the ladder is not then you won't.

I tried your way , backed up the ladder file, deleted it, and rebooted the machine, didn't work, I guess I have to contact the dealer after all, as Alexfanuc said before. thank you all for your trials to solve my problem anyway

That is a Fanuc generated alarm, you are not going to fix it by ladder edit. Fanuc controls this not the machine tool builder. But the machine tool builder has a way to unlock it. I am betting you don't want to pay the machine tool builder that is why this message is active. But there is no "back door" to this fix.

MTB can generate that alarm.
