AMERICAN AUTO-MATRIX RELEASES SMARTONE CONTROLS
American Auto-Matrix is again revolutionizing the HVAC industry with the release of SmartOneTM Controls. These Application Specific Controls are BTL listed and provide users with the openness and power of BACnet through a distribution channel.
The SmartOne line of Controllers are robust, hi-speed application specific controllers available in Rooftop, Heatpump, Fancoil, and VAV variants through distributors listed on http://www.bacnetcontrol.com. No longer is it necessary to be tied to a manufacturer in order to purchase BTL listed BACnet controls.
Programming is accomplished through serial or IP communication and the downloadable SmartOne Commissioning Wizard. This free application will take the guesswork out of programming by guiding you through a series of intuitive steps that commission the controller.

Diagnostic Switch Used at the BACnet Plugfest
At the last BACnet PlugFest, Ethernet hubs were replaced with Contemporary Controls Diagnostic Switches in order to monitor BACnet traffic generated by the participants. In the past, Ethernet hubs were used at plugfests thereby allowing software developers to use their network sniffing tools to analyze BACnet messages sent over Ethernet. Unlike Ethernet switches, Ethernet hubs allow a protocol analyzer attached to anywhere on the Ethernet network to observe all Ethernet traffic. However, Ethernet switches are hard to come by plus they force all equipment to operate at the same data rate. Is there a way to use Ethernet switches instead?
For those who follow our writings on the Industrial Ethernet University, you know we promote Ethernet switches as the best way to expand Ethernet networks. Although Ethernet hubs can be used, Ethernet switches do much more. Switches can operate at multiple data rates, operate at either half- or full-duplex, and can automatically set speed and duplex using the auto-negotiation protocol. Switches improve throughput by restricting directed message traffic to only those ports on the switch that are party to the communication. All other ports not involved with the communication will not see the message. This feature is accomplished through a learning process where the switch records in its database the port location of all initiating station addresses. Once port-address locations are learned, communication is streamlined to just two ports on the switch for a particular directed message.
This is a wonderful feature except in one situation - you are at a PlugFest and you are doing protocol diagnostics with tools such as Wireshark. In that situation, hubs have a particular feature that is important for network diagnostics, making a hub a better option than a switch.
Because Ethernet hubs operate at one speed and only at half-duplex in what is called Shared Ethernet, they do not understand the concept of station addresses. With Shared Ethernet, all hub ports will repeat the same message received on one of its ports. That means 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. Although it is possible to use port mirroring on the switch, this feature is usually only found on higher-end switches and there is no guarantee that it can capture all data.
Contemporary Controls' solution is the EISK5-100T/H Skorpion Diagnostic Switch. Although it has identical features to its cousin the EISK5-100T Skorpion 5-port switch it is missing one key feature - it does not learn. If a switch does not learn, it does not know the destination port of a directed message so it floods all ports with the message as if it was a broadcast message. This allows the diagnostic tool to be connected to any unused port. If more than five ports are needed, Diagnostic Switches can be cascaded with no loss of data.
The Diagnostic Switch is even better than a hub because the other features of switches are preserved - ability of all connected stations to operate at different speeds and duplex. Visit the 5-port Skorpion Diagnostic Switch product page at http://www.ccontrols.com/diagnostic to learn more.
Veris Industries Releases Industry's First Native BACnet MS/TP Power and Energy Meter
Veris Industries, a leader in innovative power monitoring and environmental sensing solutions, announces the release of its E50H5 Power & Energy Meter. The meter is an addition to the popular E50 family, and has been designed to meet the needs of the commercial building industry. In addition to the standard rich feature set of the E50 series, the E50H5 communicates natively over BACnet MS/TP at a data rate up to 115.2 kbaud, and offers two pulse inputs for sensors monitoring additional forms of energy.
"The E50H5 was designed for the building automation market," stated Gary Richmond, Veris' Energy and Industrial Product Manager. "Energy conservation is a primary focus in most sectors, and the building market is no exception. The E50H5 integrates energy use and consumption data into the BAS system through the industry's preferred BACnet protocol, making it easy to gain visibility of power use."
Native BACnet MS/TP Communication
The E50H5 easily connects to a BACnet control system with its embedded BACnet MS/TP protocol. The ability to network the E50H5 over an already established MS/TP trunk eliminates the need for additional wiring and network drops, significantly decreasing installed costs. The integrated functionality of the meter furthers cost savings by allowing multiple devices to be daisy-chained over BACnet MS/TP.
The energy meter fits a wide array of applications with its flexible mounting options of panel, DIN rail, or wall with optional enclosure, as well as covering 90-600 VAC and 5-32,000Amps. The E50H5 features two pulse contact accumulators for water, gas, or steam flow sensor integration, 9600 baud to 115.2 kbaud serial communication, data logging, and built-in display.
