modify PMC WIth LadderIII

Hi everybody,
I'd like to change the language for PMC messages that come on the screen of the control(Fanuc 21i) for a lathe Doossan Puma.
I edited the PMC with ladderIII and I noticed that the messages exist in several languages.By exemple A0.0 is message 2001 in english and A15.0 is the same message in french.In the ladder the message 2001 is made by R600.0 (emergency), there is no Ao.o when you make a search in the ladder.
So I don't understand how to affect messages to an other language.I mean affect R600.0 to A15.o by exemple.
Somebody has an idea?

Thank's.
