None W7760C
Other W7760A powered with 60 hour capacitor back-up
Clock Synchronization 7760A - Real-time clock runs on either 50/60 Hz or it's internal crystal. The RTC tracks time of day, day of week, month, and year (including leap year) and synchronizes the time/date for all other network devices. Daylight savings time can be enabled/disabled.
7760C - No Clock
Volatile Memory (RAM) Capacity 3072 bytes - for trend data 50 events - for alarms
Volatile Memory (RAM) Uses

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? 7760A - Yes
7760C - No
How many total trend values can be stored? 7760A - Trending of up to 16 inputs with a maximum trend sample space of 3072 bytes. Each trend point includes: input point, sampling interval, type of trend (one-shot, periodic, delta, or continuous), and start/stop date/time. A runtime log is can also be maintained for up to 15 digital inputs or outputs.
What is the controllers role in trending? Information not provided
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? Information not provided
