5/9

Trend Data Storage

Can trend data be stored in

this controller?Yes

How many total trend valuescan be stored?

The user has complete control over how trend memory is used,

including how many points are trended, how often the trend

samples are taken, how many samples are stored in the module,and whether or not the trend data will be backed up to ahistorical database on the server.

What is the controllers role in

trending?

Controller samples data either at time intervals or based on

change of value

Can controller be

programmed to 'push' data to

archive or are trends 'pulled'

from controller?

Controller can be programmed to push data to archive, or data

can be dynamically pulled from the controller for display

When full, does controller

automatically send up trenddata; overwrite data, or stop

logging data?

User defines whether controller should stop when full or beginoverwriting oldest data

Programming

Programming Method(s)

(See Also 'Software' Form)

ZN Line controllers are fully graphically

programmable using the Eikon graphical

programming software.

Resident vs. Non-Resident Program

ExecutionAll graphical programs reside in the controller.

Scheduling

(See Also 'Software' Form)

no Resident/Supervisory. This controllersupervises the scheduling of other

controllers.

yes Resident/Stand Alone. This controllercontains its own schedule.

no Non-Resident. This controller is dependent

upon another controller for its schedule.

no None. This controller has no schedulingfeatures.

no Other

Resident Energy Management

(Controller-resident energy managementfunctions/algorithms calculated and performed

by this controller. These typically require point-

sharing and can involve calculations andmultiple-loop functions. One or more of these

no Energy management algorithms for this

controller can be custom programmed

yes Pre-programmed/built-in algorithms

available, and are fully editable usingcustom programming

no Pre-Programmed/built-in with limited

editing via template-based programming

Additional Programming Functions

A library of pre-engineered control routinesprovides solutions for most zone control

applications. Custom programs can be easilywritten in EIKON using ALCs graphic

programming language.

DDC Loops (P, PI, PID)Available through custom Eikon graphical

programming

Automatic PID Tuning Feature No

Automatic-Dial Alarm Support

(See 'Software' for further information) Yes

Does controller perform multiple retires 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

X Outputs fail to a normal (unpowered)position

- Outputs fail to last position

- Other

Volatile memory functions?- Lost

X Retained for life of backup battery (shelf life


7/9

(See 'Memory' section)10 years with 10,000 hours of continuousoperation)

- Other

Upon restoration of power does the controller:

Auto-reboot without operator intervention? Yes

Automatically reset/synchronize the clock? Yes

Update all monitored functions? Yes

Generate an alarm if backup battery is

dead?Yes

Upon network or communications failure:

Does controller:

Continue to operate standalone? Yes

Operate with last global settings or user-

specified value?

User-specified default values

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?Yes

Self Test Diagnostics

Does controller have internal self-test diagnostics to check:

Processor failure? Yes

Internal hardware failure? Yes

Open/shortened sensor?

Description

ProductName(s):

LGR-25

LGR-1000Product

Description:The LGR is a router/gateway that can connect to a BACnet/IP backbone.

Product

Application(s):

Support for BACnet/IP, BACnet-over-Ethernet, ARCNET 156 kbps,MS/TP, and BACnet PTP communications are standard. A wide range ofopen and proprietary protocol translator drivers allow the LGR to also serve

as a gateway to other

manufacturers equipment. Fully programmable, the LGR can also execute

control strategies for system integration.
