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? No Hard Limit. Restricted on Object Database and Remaining Memory.
What is the controllers role in trending? The Controller gathers the samples based on whether it is set up as a polling or Change-of-Value style trend log. If polling type is defined then the controller will gather samples at set intervals.
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? All of those functions and capabilities are definable in the trend log
