------------------------------------------------------------------------------- YABE - YET ANOTHER BACNET EXPLORER ------------------------------------------------------------------------------- 1. INTRO 1.1 ABOUT Yabe is a graphical windows program for exploring and navigating BACnet devices. The project was created in order to test and evaluate the BACnet protocol. In specific I needed a platform on which to test theoretical performance throughput for huge amounts of data over MSTP/RS485 multidrop network. There're other free/open programs that also implements BACnet "exploring". So far I haven't found any to my satisfaction though. Some are worth mentioning. InneaBACnetExplorer: http://www.inneasoft.com/index.php/en/products/products-bacnet/products-bacnet-explorer.html A very nice explorer program. Same concept as Yabe. (Perhaps even better than Yabe.) However if you want to do basic things like "write" or "subscribe" to a node, you have to pay a cartful of money. Also it only supports BACnet/IP and no segmentation. BACnet Stack - By Steve Karg: http://bacnet.sourceforge.net/ A very nice old open source ANSI C project with a lot of console based sample programs. Implements both BACnet/IP and BACnet/MSTP. Steve is very active and famous in the BACnet world. The code is "singleton" based though. Meaning that the code is only able to function as either BACnet/IP or BACnet/MSTP and only 1 connection is supported. This is fine for a MCU device but not very useful on devices like PCs. I would have liked to contribute and base my tests on Steves project, but the shift to "session" based code (as agreed upon in the mail list) may have been too big a mouthful. My patches were not approved. CAS BACnet Explorer, by Chipkin Automation Systems: http://www.chipkin.com/products/software/bacnet-software/cas-bacnet-explorer Same concept as Yabe. Not as nicely finished as InneaBACnetExplorer and not as comprehensive as BACnet Stack. To be honest, the program is actually fairly horrible. It runs very poorly (at least on my machine) and the interface is not much different from a console. The documentation are very nice though. Also got a few articles about performance in MSTP. This document is subject to change. 1.2 SEGMENTATION I've implemented 'segmentation' as a part of my performance testing. To see it in action, I've added a 'HugeBlob' octet value in the DemoServer, ranging 2000 bytes. This is more than the max_adpu. The file operations are also able to use 'segmentation' if the options are set accordingly. I'm not sure if my implementation or my usage is correct though. I've followed the guidelines from the 'standard'. But my copy is rather old and I haven't found any other BACnet programs that supports it. I also support 'segmentation' with a window_size > 1 in MSTP. (This was my original purpose.) According to my 'standard' this is illegal. I hope that means that my copy is old. I was recommended to this solution by the bacnet-l mailing list. 1.3 CREDITS The projected is created by me, Morten Kvistgaard, anno 2014. A few patches and input has been given by the community. F. Chaxel has contributed a lot of the later additions (eg Foreign Device Registration, BBMD services, TrendLog & Schedule display, Calendar editor, Alarms summary, Bacnet on Ethernet, Bacnet IPv6).

USAGE 2.1 BACNET/IP OVER UDP - Start up the DemoServer program or another BACnet device. - Start Yabe. - Select "Add device" under "Functions". - Press the "Add" button in the "BACnet/IP over Udp" field. The program will now add a Udp connection to the "Devices" tree and send out 3 "WhoIs" broadcasts. If there're any BACnet/IP devices in the network they will show up in the tree. The DemoServer will show up as something like "192.168.1.91:57049 - 389002". This is the IP, the Udp port and the device_id. - If you have more than 1 ethernet card, you can also select a local endpoint ip. (Before you click the "Add"). Either select one from the list or write one by hand, if the interface doesn't have a gateway. - In order to explore the device address space, click on the device in the "Devices" tree. The program will fetch all "registers" or "nodes" from the device and display them in the "Address Space" tree. - In order to explore the properties for a given register, select the node in the "Address Space" tree. The program will fetch all properties and display them in the "Properties" field. - Write a given property by clicking the given field and insert a new value. The value will be written and read back. Be aware that many properties cannot be written. The device will decide that. - Subscribe to a given register/node by draging the node from the "Address Space" tree to the "Subscriptions" field. - Download or upload a file to the device by right clicking a file node in the "Address Space" tree and select "Upload File" or "Download File". - To send out a new "WhoIs" right click the transport in the "Devices" tree and select "WhoIs". 2.2 BACNET/IPv6 over UDP - Experimental NOT TESTED with third party device or software, and unfortunately Wireshark don't help also. - Start Yabe. - In the Options/settings menu set IPv6_support to true - Do the same as explain in 2.1, but the Local endpoint combo box shows now IpV4 & IPv6 available interfaces. Choose an IPv6 one (the [FE80::...] will be generaly OK, or simply try [::] ). If the combo is empty it's equal to the default IPv4 address ! - If the option YabeDeviceId is -1, a random VMac (with duplication test) is used. - Register as a foreign device & BBMD services also working on IPv6. In the Foreign Device Registry form one can give an IPv6 remote address or also the host name. - Feedback is very welcome. 2.3 BACNET/MSTP OVER PIPE - For general usage refer to section 2.1. - In the "Search" dialog select "COM1003" in the port combo box and press "Add". This will add a MSTP pipe created by the DemoServer. Notice that the "Source Address" defaults to "-1". This is not a valid address and you will not be able to communicate with the device through this. The program will still be able to listen in on the network though. The program will now list all the devices that communicates on the network. And it will also display all "PollForMaster" destinations that goes unanswered. This way you'll be able to determine what source_address to give to the program. - Click on the device node in the "Devices" tree. If the source_address is configured to "-1" the program will ask if you will define a new one. You must do so, in order to continue communication. 2.4 BACNET/PTP OVER PIPE - For general usage refer to section 2.1. - In the "Search" dialog select "COM1004" in the port combo box and press "Add". This will add a PTP pipe created by the DemoServer. The BACnet/PTP transport is meant for 1-to-1. Eg. RS232 or ... usb? So far I haven't found any others easy accessible tools that also supports it. So I haven't been able
