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? No
How many total trend values can be stored? None. Feature available through SF1 or SAGEMAX
What is the controllers role in trending? None. Feature available through SF1 or SAGEMAX
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? No. Feature available through SF1 or SAGEMAX
Programming Method(s) Programmed using menu-driven SOLOPro/NB-Pro software or the SOLOTool hand held operating device.
Resident vs Non-Resident Program Execution All program execution is designed to be controller resident although the AspectFT Matrix Area Controller or SageMAX can be programmed to perform/supervise unit controller functions. Controller-resident program execution is ensured by selecting the proper controller for the application.
Scheduling
Resident/Supervisory. This controller supervises the scheduling of other controllers. Only when configured as a Bypass controller.
Resident/Stand Alone. This controller contains its own schedule.
Non-Resident. This controller is dependent upon another controller for its schedule. Controller can be configured to receive broadcast schedules.
None. This controller has no scheduling features.

Resident Energy Management
Energy management algorithms for this controller can be custom programmed
Pre-programmed/built-in algorithms available, and are fully editable using custom programming
Pre-Programmed/built-in with limited editing via template-based programming
Controller is not typically used for energy management functions

Automatic PID Tuning Feature No
Automatical-Dial Alarm Support No. Feature available through AspectFT Matrix Area Controller or SAGEMAX

Are multiple destinations possible? No. Feature available through AspectFT Matrix Area Controller or SAGEMAX
Upon controller power loss or hardware failure:
Are network communications affected? Information not provided
Is loss recognized on/by the network and alarm reported? Yes. Continuous controller diagnostics results in an alarm at the SAGEMAX or AspectFT Matrix Area Controller in the event that the control program stops or aborts.
DO and AO response?
Outputs fail to a user pre-specified position
Outputs fail to a normal (unpowered) position
Outputs fail to last position Actuators
Other
Volatile memory functions?
Lost
Retained for life of backup battery
Other Information not provided
Upon restoration of power does the controller:
Auto-reboot without operator intervention? Yes
Automatically reset/synchronize the clock? Yes (Bypass flash)
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
Does network automatically reconfigure upon restoration? Yes
Does network store 'loss of communications' alarm with time of event? No
