  • Page 128: Communications Protocol

    ® Advanced Energy COMMUNICATIONS PROTOCOL The AE Bus communications protocol uses pure binary data (nothing is coded into ASCII, for example), and is designed for multi-drop communications networks (networks that contain two or more nodes). The host computer is always the master unit. Slave units transmit only after receiving a message packet from the master, and then only to the master.

    ® Advanced Energy If the MDXII unit receives a request for data or status information, it gathers and sends the requested information. Otherwise, it evaluates the incoming command and sends a message packet that contains a 1-byte data value (CSR code) to the host (see Table 7-10 on page 7-57).

  • Page 134: Communications Protocol

    ® Advanced Energy Setting Profibus Baud Rates The Profibus interface has an auto-baud detect feature, which will lock onto the baud rate the master (host computer) is trying to communicate with. These rates are in discrete steps from 9.6kbit up to 1.5Mbit. This interface will operate much like a modem or FAX machine in that at startup, there is a small delay while the interface traverses the different baud rates and then locks in.

  • Page 135: Table 7-6. Configuration Of Profibus Upload Packet

    MDXII Power Supplies Profibus Upload Packet During every Profibus data exchange, the unit supplies a 14-byte response to a download (“outbytes”) packet. Table 7-6 on page 7-15 shows this response or “upload packet.” These bytes are also known as “inbytes” at the Profibus master. Table 7-6.

  • Page 137 MDXII Power Supplies In the first status byte 0, bit 5 (the active toggle bit) indicates, in general, the status of the Profibus interface. After the unit has powered up, this bit’s continuous change indicates that the Profibus interface is ready. During operation, a cessation of this change indicates that a communication problem exists.
  • Page 138 ® Advanced Energy Profibus Master-Specific Files Some PLCs use computer files called “type files” to compile their Profibus programs.
