Date Last Saved: 4/22/2004 10:16:00 AM

Product Name(s): LINC-200 LON Integrated Node Connector
Product Description: Provides a LON interface to and control of 3rd party LON devices using LONWORKS technology.
Product Application(s): Designed to provide scheduling, alarming, and trending of 3rd party LONWORKS based devices. Can also perform some local control functions over the network (but has no physical I/O). Stores up to 20 separate schedules for secondary network devices/controllers. Stores data for up to 20 alarm points originating at designated controllers. Transmits alarms over LON to OWS or SMC-200 Site Management Controller. Records/stores up to 25 sets of trend data. Performs up to 10 PID control calculations for networked LON devices. Performs up to 2 Optimal Start/Stop calculations for networked LON devices.

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? Yes
How many total trend values can be stored? Information not provided
What is the controllers role in trending? The LINC-200 can trend averages, current data, minimum and maximum values at user defined intervals, and can also track/store change of state.Trends are 'pulled' from controller by the OWS.
Can controller be programmed to 'push' data to archive or are trends 'pulled' from controller?
When full, does controller automatically send up trend data, overwrite data, or stop logging data? If SI trend data buffer fills before being called by archive workstation, old data is overwritten.
