Contemporary Controls participated in BACnet® International’s PlugFest 2011, which allows our engineers to perform interoperability testing for our BACnet enabled solutions.
Over 100 engineers from over 30 companies met in Atlanta, GA this November, which is the largest PlugFest to date.
"The environment is very friendly and it provides us with a neutral setting to test the interoperability of our products with BACnet devices from other vendors," said Bennet Levine, R&D manager at Contemporary Controls. "This allows us a unique testing opportunity that results in improved product performance."
As is often the case during diagnostic testing, the debate of hubs vs. switches was discussed.
Generally, Ethernet hubs are used at PlugFest to allow software developers to use network sniffing tools such as Wireshark to analyze BACnet messages sent over Ethernet. Hubs are preferred over switches for diagnostic testing because hub ports will repeat the same message received on one of its ports. A diagnostic tool connected to any unused hub port can view all the traffic sent over the network. A switch will restrict port traffic and cause a diagnostic tool to fail to see messages except for broadcast messages.
However, using a hub means the developer is without the many features of a switch, such as the ability of all connected stations to operate at different speeds and duplex.
Contemporary Controls has a solution which was used by its developers and several other vendors. The Skorpion Diagnostic Switch has all the features of a switch but it does not learn, which means that it floods all ports with a message as if it were a broadcast message. This allows a diagnostic tool to be connected to any unused port to see all traffic. If more than five ports are needed, Diagnostic Switches can be cascaded with no loss of data. Another advantage of the Diagnostic Switch is that all participants in the PlugFest can connect at the data rate of their equipment with no concern for other participants' data rate.
In addition to using the Diagnostic Switch, the new BASview, a stand-alone, embedded, web-based graphical interface for building automation systems, was tested at the PlugFest. The BASview was used with various BACnet server devices and was accessed by a web browser to provide client functionality to any BACnet/IP or Modbus TCP system.
The BASrouter was tested with several MS/TP devices. The BASrouter will support three-way routing between BACnet/IP, BACnet Ethernet and BACnet MS/TP. Any two or all three protocols can be routed. As an aid to troubleshooting, a diagnostic page will display the number of messages received and sent for each of the protocols supported.
The BASremote and a new Ethernet field control device also were tested with several BACnet clients.
"It would be very difficult to do this type of testing between multiple vendors without the organizational efforts of BACnet International," said Levine. "It’s an example of BACnet International and the participants’ continued commitment for open, standard protocols."

C Erfinder und Unix Author verstorben
Der Erfinder von C und Co-Author von Unix ist am 8. Oktober diesen Jahres verstorben.
Damit verlässt uns schon der zweite Pionier des Kommunikationszeitalters in einem Monat. Zwar nicht so populär und reich wie Steve Jobs, aber mindestens genauso wenn nicht sogar noch wichtiger für unser heutiges Verständnis von Computern.
Damit verlässt uns schon der zweite Pionier des Kommunikationszeitalters in einem Monat. Zwar nicht so populär und reich wie Steve Jobs, aber mindestens genauso wenn nicht sogar noch wichtiger für unser heutiges Verständnis von Computern.
Ohne ihn hätten wir weder Betriebssysteme wie Linux und MAC OS, noch Microcomputer, MP3 Player und Waschmaschinen. Ohne Unix gäbe es auch keine Alternative zu Windows und damit auch weniger leistungsfähige Server Systeme, also auch keine Cloud. Und wie sähe erst das Internet aus ohne Unix und C? Ohne C und seine Weiterentwicklungen gäbe es noch nicht einmal die so beliebt gewordenen Kaffeevollautomaten.
Gedenken wir seiner; nehmen wir uns die Zeit kurz inne zu halten und darüber nachzudenken welche Annehmlichkeiten wir Ihm alles zu verdanken haben.

Using the Skorpion Diagnostic Switch with Wireshark®
One benefit of switched Ethernet technology is that the switch restricts directed messages to only those ports party to the communication. This improves overall network throughput by not burdening end stations with useless traffic. However, this feature makes protocol debugging difficult because a network protocol analyzer tool, like the free, open-source Wireshark, attached to an unused port on the switch cannot observe any directed messages on other ports. In the past, the solution was to change out the switching hub with a repeating hub — but with the Skorpion Diagnostic Switch this is unnecessary.
The Skorpion Diagnostic Switchretains all the virtues of switched Ethernet technology (including Auto-MDIX and auto-negotiation) but with one exception — no address learning. Thus, all messages (directed, multicast, broadcast) are floodedto all switch ports so that network sniffers such as Wireshark can be used to observe all network traffic that passes through the switch. The switch can be permanently installed or carried from one site to another as needs arise. It can be used for control panel installations if you need the ability to diagnose problems in the field. It can also be used in a development environment when debugging code.
The Wireshark.org website claims that Wireshark is the world’s foremost network protocol analyzer. It lets you capture and interactively browse the traffic running on a computer network. It supports hundreds of protocols including BACnet thanks to the numerous individuals who support the Wireshark open-source application. It can work with both wired and wireless networks. It is extremely handy when troubleshooting tough network problems as long as you can capture the traffic of interest. With switched Ethernet this can be a problem and that is where the Diagnostic Switch comes into play.
Using the Skorpion Diagnostic Switch with Wireshark calls for some special considerations that are discussed in a recently published Application Note. Topics include:
