Product Description: The KMDigital Terminal SCUs all have a common processor but each have a different I/O board (4 inputs/4 outputs). They can operate stand-alone or communicate peer-to-peer when networked together. They have pre-programmed control sequences but can be user modified for special sequences, or totally reprogrammed.
Product Application(s): The following part numbers and descriptions outline the various specific applications for the KMDigital Terminal SCUs. Specific I/O corresponding to these controllers are described in the next section.

Controller Operating System
Additional Information These controllers can be purchased with an optional on-board real time clock with auto-reset of time across network after power restoration.
* 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? All Terminal SCUs: Up to 2 trend logs and 2 runtime totalizers.
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.
Programming Method(s) The Terminal SCUs come pre-programmed for their specific applications, but can be reprogrammed as needed. Programming uses a combination of fill-in template and characteristic pick bars for I/O point, virtual point (VARs), PID control loop, trend log, schedules, and runtime log definition. They use a non-proprietary (open) line-based programming language (ControlBASIC) for operating sequences.
Resident vs Non-Resident Program Execution All program execution is resident.
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)
Optimal Start/Optimal Stop
Peak Demand Limiting/Load Shedding
Economizer (enthalpy, dry-bulb, CO2, modulating/2-position, etc.)
Other "Canned" programs available
Additional Energy Management functions are resident at SI
Additional Programming Functions Custom programming can be done. Weekly schedule is standard. More detailed scheduling can be provided by a Local Controller (with clock option) or LAN Controller.
Enthalpy and wet-bulb algorithms are built in to the controller logic and can be used as needed.
DDC Loops (P, PI, PID) 4 loops (PID)
Automatic PID Tuning Feature No
Automatical-Dial Alarm Support Available from controller using optional CommTalk DEM communications interface
Does controller perform multiple retries and buffer/store alarm until connection is made? Yes, via CommTalk DEM
Are multiple destinations possible? Yes, via CommTalk DEM
Upon controller power loss or hardware failure:
Are network communications affected? No, once the next network token-pass determines unit is offline.
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
Volatile memory functions?
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. Use of at least one KMD-5801 or 5831, KMD-5210 'LAN Controller' or one KMD7xxx'C' Controller is required to reset clocks across the secondary network.
Update all monitored functions? Yes
Generate an alarm if backup battery is dead? Information not provided.
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, restored controller generates new token.
Does network store 'loss of communications' alarm with time of event? No
Additional Information (optional)
Self Test Diagnostics
Does controller have internal self-test diagnostics to check:
Processor failure? No
Internal hardware failure? No
