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. Depending on the particular setup the trend can push data to an archiver or the archiver can pull data from the trend.
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? All of those functions and capabilities are definable in the trend log.
Programming Method(s) Uses Delta's 'GCL' program editor. GCL is line-code programming using a language-based syntax.
Resident vs Non-Resident Program Execution Resident
Scheduling
Resident/Supervisory. This controller supervises the scheduling of other controllers.

Automatical-Dial Alarm Support Available from front-end Operator Workstation and Primary Control Unit.
Does controller perform multiple retries and buffer/store alarm until connection is made? Yes
Are multiple destinations possible? Yes
Upon controller power loss or hardware failure:
Are network communications affected? No
Is loss recognized on/by the network and alarm reported? Yes
DO and AO response?
Outputs fail to a user pre-specified position
Outputs fail to a normal (unpowered) position
Outputs fail to last position
Other
Volatile memory functions?
Lost
Retained for life of backup battery
Other If battery dies during loss of power, the database is reloaded on power-up from the Eeprom
Upon restoration of power does the controller:
Auto-reboot without operator intervention? Yes
Automatically reset/synchronize the clock? Yes
Update all monitored functions? Yes
Generate an alarm if backup battery is dead? No
Upon network or communications failure does controller:
Continue to operate standalone? Yes
Operate with last global settings or user-specified value? N.A.
Do broken network segments continue to communicate within the remaining segment?
(Note: May depend on proper termination of segments for higher speed networks.)
Yes. When the secondary network is broken, a token-based peer-to-peer system generates a second token to operate the bus as two peer-to-peer systems.
Does network automatically reconfigure upon restoration? Yes
Does network store 'loss of communications' alarm with time of event? Yes
Additional Information (optional)

Does controller have internal self-test diagnostics to check:
Processor failure? Yes
Internal hardware failure? Yes
Open/shortened sensor? Yes
