LanSTAR II

Primary Control Unit
LanSTAR II
Date Last Saved: 4/4/2004 2:21:31 PM

Product Name(s): LanSTAR II
Product Description: The LanSTAR II polls a secondary control unit network for information, processes that information, then sends control tasks back to the Secondary Control units for execution. LanSTAR IIs also communicate with each other peer-to-peer over an Ethernet network connection. LanSTAR II is TCP/IP compatible, accessible from any internet connection.
Product Application(s): Supports general HVAC end-use devices including air-handling units, VAV systems, chillers/boiler/central plant control, lighting control and distribution systems.

Additional Information
* Items in NV memory are not lost upon power or battery failure. Other types of NV memory such as EPROM, NOVROM, etc. do not directly impact system performance.
Can trend data be stored in this controller? Information not provided.
How many total trend values can be stored? Information not provided.
What is the controllers role in trending? Resident programming gathers and stores trend data on-board. At set intervals, data is sent to server for archiving.
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller? Information not provided.
When full, does controller automatically send up trend data, overwrite data, or stop logging data? Information not provided.
Programming Method(s) Web Browser based proprietary language uses free form logic in a non-compiling form. Real time error checking provided.
Resident vs Non-Resident Program Execution Resident
Scheduling
Resident/Supervisory. This controller supervises the scheduling of other controllers.
Resident/Stand Alone. This controller contains its own schedule.
Non-Resident. This controller is dependent upon another controller for its schedule.
None. This controller has no scheduling features.

Do broken network segments continue to communicate within the remaining segment?
(Note: May depend on proper termination of segments for higher speed networks.)
Yes
Does network automatically reconfigure upon restoration? Information not provided.
