ACS 550 Modbus communication

While communicating from ABB ACS 550 to ABB AC31 PLC through Modbus, it is noted that ACS 550 has address protocol with prefix '4', which renders the address to be beyond 40000 value. Whereas PLC Function block attributes WORD value to the Address input, which cannot be more than 32768. Could anybody help?
