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? 12000 Samples
What is the controllers role in trending? The controller gathers and stores data.
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 controller trend data buffer is full, the last data is overwritten by the new one.
Programming Method(s) Through any LNS compliant software
