Product Name(s): KMDigital LAN Controller (KMD-5210)
Product Description: The KMDigital LAN Controllers are general purpose, expandable (to 128 I/O), programmable controllers and/or supervisory interfaces. All I/O is provided by expander cards and can be customized per application needs. The LAN Controller can also serve as a supervisory interface for larger KMDigital network installations with more than 124 Local (5800 Series) and Terminal (7000 Series) controllers. Two subnetworks of 124 SCUs each may be supported. In either capacity, they can operate stand-alone or communicate peer-to-peer with all other KMDigital controllers.
Product Application(s): The LAN Controller can be used as a primary controller and/or supervisory interface to support secondary controllers. It can be used for all general-purpose HVAC applications including air-handling units, chillers/boiler/central plant control and distribution systems, data acquisition, and other related industry applications.

Additional Information Clock capacitor backup is 72 hours and requires no maintenance.

Programming in executed from RAM and is backed in FLASH at 24 hr or closer intervals.
* 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 96 trend reports can be stored consisting of 6 points per report and 255 values per point (for a total of >146000 stored points per controller)
What is the controllers role in trending? Programming resident within controller gathers and stores trend data on-board. Trend data is written to flash daily, or more frequently as programmed in ControlBASIC using "write to flash" command.
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? If controller trend data buffer fills before being called by archive workstation, old data is overwritten.
Programming Method(s) The PLC-Series controllers use 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. Programming is retained in non-volatile (FLASH) memory. Any calculations temporarily stored in RAM are lost.
Scheduling
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.

DDC Loops (P, PI, PID) 64 PID loops can be programmed
Automatic PID Tuning Feature Yes (See ControlBASIC Software form for further detail)
Automatical-Dial Alarm Support Available from controller.
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 Retained if recommended UPS is used
Upon restoration of power does the controller:
Auto-reboot without operator intervention? Yes
Automatically reset/synchronize the clock? Yes. The LAN Controller will also automatically reset clocks across the networks. Use of at least one Local or LAN controller is required to reset clocks across a KMD subnet bus.
Update all monitored functions? Yes
Generate an alarm if backup battery is dead? N/A
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 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? Yes - at OWS
Additional Information (optional)
Self Test Diagnostics
Does controller have internal self-test diagnostics to check:
Processor failure? No
Internal hardware failure? No
Open/shortened sensor? Yes
Others? Ouputs short circuit protected
