Acs355 With pm554 Mdbus Communication

I make a Com_Mod_Mast Block and i think the communication was ok between the plc and the VFD Because err and Done in the block was changed from 0 to 1
but i have no data changed in my array , so my question is what are the acs355 mdbus register address and what should i enter in (ADDR and NB) in (Com_mod_mast) If i need the data in 5310 ....5315 .
