mb:setregisters() and LM values

[SigmaTec]

So, is this correct to write an INT64 into 4 registers?

value = event.getvalue()
raw = knxdatatype.encode(value, dt.float32).dataraw

r1 = raw:byte(1) 
r2 = raw:byte(2)
r3 = raw:byte(3) 
r4 = raw:byte(4)

register = 3204
mbetregisters(register, r4)
mbetregisters(register+1, r3)
mbetregisters(register+2, r2)
mbetregisters(register+3, r1)
