To be clear - RS485 is a method of electrical connection for data communication. DH485 is a communication protocol developed by Allen Bradley which can be implemented over RS485 and RS232. For the Siemens HMI to communicate it must be able to use the DH485 protocol. Look into the specifications for it. (I have never used it.)
