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? Information not provided.
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? Information not provided.
When full, does controller automatically send up trend data, overwrite data, or stop logging data? Information not provided.
Programming Method(s) Metasys software is used to program the controller.
Resident vs Non-Resident Program Execution All program execution is resident. Programming is retained in non-volatile (Flash) memory. Any calculations temporarily stored in RAM are lost.
Resident/Supervisory. This controller supervises the scheduling of other controllers.
Resident/Stand Alone. This controller contains its own schedule.
Non-Resident. This controller is dependent upon another controller for its schedule.
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
Specific Pre-Programmed Algorithms Available
None (custom programming only)
None (not applicable)

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.)
Information not provided.
