    1. Introduction  The Babel Buster BB2-7030 is a BACnet gateway and router. It may be used as either or both, in various ways for different applications. In its simplest form as a router, it will route a single MS/TP network to a single BACnet IP network. It may be used as a router to interconnect multiple BACnet MS/TP via IP networks.
  • Page 5 The BB2-7030 may also be used as a gateway to connect BACnet MS/TP or BACnet IP to either Modbus TCP or SNMP. There are two variations of the BB2-7030. The BB2-7030-01 may be used as a gateway to connect BACnet MS/TP or BACnet IP to Modbus TCP.

    PC’s IP address for 1.2.3.4. This generally works, but if this fails, you will need to temporarily change your computer’s IP address to a fixed address that starts with 10.0.0. and ends with anything but 101. BB2-7030 User Guide – Rev. 1.0 Page 3...
  • Page 7 “root” using password “buster”. You should log in as “root” if you will be changing the IP address. (g) To can change the IP address of the BB2-7030, go to the Local Host page under System :: Setup. The following page should appear. Change the IP address, and subnet mask and gateway if applicable.
  • Page 8 RAM copy of the configuration file. To make your changes other than IP address permanent, you must click Save on the Config File page (System :: Setup :: Config File). BB2-7030 User Guide – Rev. 1.0 Page 5...

  • Page 9: Minimum Bb2-7030 Gateway/Router Setup

    The BB2-7030 requires only minimal configuration to be useful in its simplest form. First, you must assign a device instance to the BB2-7030, and you do this via the BACnet IP Port page. You may leave all other settings at their default. You could leave the device instance at its default as well.
  • Page 10 The last item that should be configured on the above page is Hop Count. If you are only connecting MS/TP to BACnet IP locally, set that count to at most 2 since you will not need to make any additional router hops. If there are additional routers in your system, the hop count needs to be the maximum number of routers that a message must hop to reach the final destination.
  • Page 11 The primary use of hop count is to force packets on the network to be discarded faster, particularly in the event of router misconfiguration that results in a continuous loop. BB2-7030 User Guide – Rev. 1.0 Page 8...

    Who-Is-Router. You may enter the remote router's address as an MS/TP MAC address, or an IP address optionally with port number. If no port number is given, the BB2-7030's own local port number will be used. IP should be given in the form of 192.168.1.199:47808 (for example) or just 192.168.1.199.
  • Page 13 It should also be noted that if some external BACnet network management tool sends a router table initialize message to this device, the entire page shown here will be replaced. After a delay of a few minutes, the new contents of this page will be auto-saved to the XML configuration file for subsequent reload.
  • Page 14 The networks listed as “Connected” in the diagram are the locally connected network numbers. The remaining networks are router table entries. Each entry tells the local router which network the given net number will be found on. BB2-7030 User Guide – Rev. 1.0 Page 11...

    Data may be placed in the local objects by other devices writing to the BB2-7030, or by the BB2-7030 querying other devices. When the BB2-7030 is configured to query other devices, these operations are defined by “read maps”...
  • Page 16 Out of Service means any polling of the slave device will stop. While out of service, the present value may be written by the BACnet client. Data may be forced via this web page at any time, but will be overwritten by the next poll unless the object is out of service.
  • Page 17 BACnet object. The designation R means read from external device, and W means write to external device. The destination of data for an Analog Output object will be writing to another BACnet device, or to a Modbus device. The external device will be updated upon change of source data and/or periodically as defined by the Write Map.
  • Page 18 Value window, check Force, and click Update. Out of service means the external device will not be written. Values written by the BACnet client will be retained, but only applied when this object is placed back in service. At that time, the highest priority value will be written to the external device.

  • Page 19: Using The Bb2-7030 As A Bacnet Client

    The BACnet client is used to query other BACnet devices, obtain their Present Value data, and store a copy of that data in the BB2-7030’s own local objects. From there, the data may be accessed by Modbus TCP or SNMP devices, or other BACnet devices when application specific reasons make this approach more preferred than direct routing.
  • Page 20 Note that 47808 is the default 0xBAC0 port number. If no port number is given, the port configured on the BACnet IP Port page will be used (the BB2-7030's own port). Map number simply tells you where you're at on the list of register maps. Click "next" and "prev"...

    (This definition of proxy is not what is meant on the Slave Proxy page.) The BACnet client, or master, in the case of a gateway would treat the BB2-7030 as a single device having some number of objects containing data. The main reason one would use the BB2- 7030 as a gateway for BACnet to BACnet data transfer is to permit some sort of data filtering or manipulation or alternate form of representation as the data is passed through.

  • Page 29: Configuring The Bb2-7030-01 As A Modbus Tcp Server

    The Modbus TCP server is simply a collection of registers that may contain data. The source of that data in the case of Babel Buster BB2-7030 can be any of several possible sources. It may be read from another Modbus device. Another Modbus device could have put it there by writing to the BB2-7030.
  • Page 30 BACnet, and Read from Output objects to receive output from BACnet. Attempting to write a BACnet Output object from Modbus will not work properly. You must think of your Modbus device as the physical I/O being accessed from BACnet. If you want to make your Modbus device write to an Output object on another BACnet device, use the BACnet client mapping to translate a local Input to remote Output on the BACnet side.

    9. Configuring the BB2­7030­01 as a Modbus TCP Client  The BB2-7030-01 can be a Modbus client or server. As a client (master) you can read Modbus data from, or write Modbus data to, other Modbus servers (slaves). The BB2-7030 will periodically poll the other Modbus devices according to register maps you set up. The Modbus server (slave) devices that you will read/write are defined on the Devices page.

    The BB2-7030 can be “slave” on both BACnet and Modbus sides at the same time. The BB2- 7030 can also be “master” on both BACnet and Modbus sides at the same time. To be a slave on both sides, no client functions need to be configured (no read/write maps entered). To be a master on both sides, both the BACnet client and Modbus client need to be configured.

    11. Using the BB2­7030­02 as an SNMP Server (Agent)  The BB2-7030-02 can act as an SNMP agent or server. You select which BACnet objects are to show up in the MIB, and the MIB is created dynamically as you fill out the list of objects. Once the MIB is created, any standard v1 or v2 SNMP manager can access the data. Integer data is most universally recognized by SNMP.

    12. Using the BB2­7030­02 as an SNMP Client (Manager)  The BB2-7030 has the ability to be an SNMP client. In “master/slave” terms, this would be the master. Configuring the SNMP client starts with defining one or more SNMP devices that will be queried. Then, like the other possible client functions in the BB2-7030, you set up read and write maps.

    The BB2-7030 can be “slave” on both BACnet and SNMP sides at the same time. The BB2-7030 can also be “master” on both BACnet and SNMP sides at the same time. To be a slave on both sides, only the SNMP MIB needs to be set up under the SNMP Agent tab. To be a master on both sides, both the BACnet client and SNMP client need to be configured.

    17. Hardware Guide  Wire the BB2-7030 as illustrated above. Follow all conventional standards for wiring of EIA-485 networks when connecting the MS/TP EIA-485 (RS485) network. This includes use and termination of shield, termination of the network, and grounding. IMPORTANT: Although EIA-485 (RS485) is thought of as a 2-wire network, you MUST include a third conductor connected to GND or common at each device so that all devices are operating at close to the same ground potential.
  • Page 66 If so, count the flash code and report it to tech support. When the BB2-7030 is powered up, there is a pause of a couple of seconds while the red LED is on. Red at power up means the window is open for coprocessor firmware update.

  • Page 67: Trouble Shooting

    Also, be sure the EIA-485 wiring is “clean”, and that the BB2-7030 is not on a long “stub” off the main network. Recheck wiring polarity as well if adding the BB2-7030 took the network down.
