I understand that Carrier offers factory installed controls. What are the advantages?
Factory-installed controls offer many advantages, including:
Reduced installation costs
Controllers installed in the factory are much more cost effective due to assembly line techniques. You do not have to pay personnel to field install these controllers with custom programming that has not been factory tested.
Utilizing factory tested programs ensures the equipment is controlled in a manner that is consistent with the design and intent of the equipment.
You can easily understand parameter-driven programming without custom code. Custom code is often written in a cryptic manner without documentation, which forces you to spend extra funds subcontracting to the original installer.
Factory-mounted controllers ensure that the equipment operates exactly as designed.
Third party controllers can operate inefficiently, causing equipment damage and premature wear and tear, due to starting and stopping the equipment excessively.

NEW Skorpion Diagnostic Switch Teams Up with Wireshark
Frank Schubert of MBS GmbH had an interesting article in the February 2011 issue of BACnet International Journal entitled BACnet Protocol Analysis Using Wireshark. This free open-source software is very popular when analyzing protocols over Ethernet and as the article points out, it can be used to analyze BACnet MS/TP traffic as well. In order to monitor network traffic, your tool needs to be able to see the network traffic which is tricky with a switched-Ethernet network. Ethernet switches will pass directed messages only between devices party to the message. This means that a protocol analyzer attached to a port on the same Ethernet switch that is passing the message will not see the message. In the article Frank suggests three ways to connect a computer running Wireshark to the network being monitored while avoiding the switched-Ethernet problem.
The first method is to use an Ethernet hub but as he says installing a 10 Mbps hub on a system that was operating at 100 Mbps forces a lower throughput. The resulting system is no longer reflective of the system without the hub. We would also add that finding an Ethernet hub is difficult anyway.
The second approach is adding a passive Test Access Point (TAP). He says this approach is pricy.
The third approach, which he recommends, is to use a switch with port-mirroring. Port-mirroring is a feature that is found in managed switches and Contemporary Controls' managed switches have this feature. With port-mirroring, a port on the switch can be configured to see all the traffic on a designated port. The computer running Wireshark attaches to the mirrored-port and the operator changes the designated port based upon what port on the switch he wants to monitor. Frank suggests that a switch with port-mirroring capability be installed in each equipment room that has devices attached to the IT backbone.
We suggest that there is a fourth option and that is Contemporary Controls' EISK5-100T/H Diagnostic Switch. As we mentioned in the last newsletter, the Diagnostic switch retains ALL the features of an unmanaged switch such as auto-negotiation and auto-MDIX except for one significant feature - it does not learn. Because it does not update its database of source MAC addresses and switch port pairings, the Diagnostic Switch continues to flood all ports with messages as if they were broadcast messages. This allows protocol tools such as Wireshark to capture any network traffic that goes through the switch regardless of the port location of the traffic. The Diagnostic Switch only has five ports so if more ports are needed, Diagnostic Switches can be cascaded.
Active Test Access Point - Here is a suggestion for your next project. Instead of installing a managed switch with port-mirroring in each equipment room, install a five-port Diagnostic Switch in each control panel that has an Ethernet connected BACnet building controller (B-BC). Just about all the traffic you would be interested in is going to be related to the building controller. Insert the Diagnostic Switch between the building controller and the IP network. If the building controller is located at the end of a single Ethernet drop, the Diagnostic Switch will act as a three-port active tap with one connection to the building controller, one connection to the IP network and one connection reserved for a protocol tool such as Wireshark running on a laptop. In fact with this setup you gain two additional spare ports. It is not necessary to leave the laptop connected. Just connect it when you need to. The Diagnostic Switch is active in the network at all times but will not reduce any communications throughput other than the normal latency of a store-and-forward Ethernet switch. Just plug in you laptop when you want to do protocol analysis, configure a device on-line or to observe web pages. It is very convenient and the Diagnostic Switch is priced the same as a standard five-port unmanaged switch.
If the building controller is located mid-span of the IP network with a backbone connection coming into the control panel and exiting the control panel, use the Diagnostic Switch for all connections leaving two spare connections - one for the laptop and one additional spare. You can also use the spare port for connection to another control panel. With either of these situations you will be able to observe all traffic from all ports but throughput could be impacted due to the flooding of traffic. However, with modest traffic you might not even notice the difference plus you gain the convenience of having a network diagnostic port ready at all times to be used.

BACnet scalability at the heart of new system and component capabilities
Siemens Industry, Inc. has enhanced its line of APOGEE� and TALON� Building Automation Systems to include BACnet web-based remote system monitoring, commanding, alarm management, scheduling and trending functions. The new BACnet enhancements also improve operator efficiency and convenience with browser-based internet system access and control functionality.
New features include controller-based BACnet web pages for viewing, commanding and monitoring system information. Local and remote access to configure and edit the Web-based controller database has also been added, as well as cost saving BACnet MS/TP programmable controllers, remote I/O and a local controller user interface. The Web browser feature also mitigates the necessity for a dedicated PC based workstation through its simple-to-use interface. Any PC or laptop connected to the Internet can access the controller database and maintain system control remotely.
"The APOGEE and TALON product lines specifically address the growing need for sophisticated, standard protocol based controls," says Nancy Stein, director, Product Management, Siemens Industry, Inc. "The improvements provide the flexibility to meet existing and emerging control requirements for smaller buildings and systems, as well as enable it to grow and be part of the largest campuses and systems."
BACnet, the HVAC industry standard network protocol, delivers system-wide control and operations management through a single interface. The APOGEE and TALON BACnet web based systems are comprised of all BTL (BACnet Testing Laboratories) certified components, including a BAS workstation, a plug and play controller embedded web server and field level network architecture.

The Viconics VBZS BACnet� Zoning System has been specifically designed to bring a simple scalable BACnet� solution to the commercial mid-market without the cost associated with typical DDC type zoning systems.
The system is comprised of two main components: the VZ7200 pressure dependent VAV controller and the VZ7656, which serves as a master-scheduler, rooftop unit controller, static pressure bypass controller, and status display via the local LCD user interface. The VZ7200 can be ordered with an on-board PIR (Passive Infra Red) occupancy sensor. The PIR allows for control of demand based occupancy strategies, further optimizing the controller to be able to provide greater energy savings to unoccupied zones during scheduled occupancy periods.
Together, these components work to provide exceptional comfort and system performance rivaling more costly and complex programmable automation systems and can be installed at a fraction of the total installed cost of a comparable system. System set-up, installation and commissioning have been simplified by eliminating the need for separate commissioning equipment or tools. All necessary configuration, addressing, zone-weighting etc., is accomplished via the local LCD interface included on all components of the system. BACnet� object mapping is seamlessly accomplished without the need for complex programming tools.
The most unique feature of the zoning system is its scalability. A single Roof Top Unit can support up to 64 individual zones.
The VBZS offers owners unparalleled flexibility through the use of the open BACnet� communication protocol. The system can be complimented with your choice of BACnet� controllers or graphical workstation software. Moreover, since no other programming tools are required, mechanical service technicians can quickly and easily service the system without support from other controls vendors.
