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? 244
What is the controllers role in trending? Trend objects are points resident in the BMTX.
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? When full, the data will be overwritten on a first in first out basis. Reports can be set up to capture data before it is overwritten.
