Product Name(s): MACH-Stat Space Controller
Product Description: The MACH-Stat and MACH-Stat-ND are fully programmable space controllers.
Product Application(s): The MACH-Stat controller is designed for space control applications where user access is required. The built-in LCD screen allows operators to access, view, change, and override up to 42 differnt points within a MACH-System. The MACH-Stat-ND controller is designed for space control applications where an LCD display is not required.

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? Up to 3 trend logs can be stored consisting of 6 points per log with 150 samples per trend.
What is the controllers role in trending? Collection and storage for local points
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? Overwrites data
Programming Method(s) The MACH-Stat and MACH-Stat-ND can be programmed using a PC connected via the network or locally via an X-Port convertor.
Resident vs Non-Resident Program Execution MACH-Stat points can be controlled by resident or non-resident programs.
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.
