SANDIA POINT IDENTIFICATION SCHEME

Sandia\'s 8-character point identification scheme was developed so that
each real EMCS point uniquely indicates the system type and point
function. The scheme is used with a FID letter designator to create a
12-character Descriptor for each hardware EMCS point. EMCS virtual
points may also incorporate the 8-character point identifier (dependent
on the virtual point's function). The 8-character system type/number and
point type/number portions of the Descriptor form the point label used
by Sandia on all construction drawings.

The point descriptor is in the following form:

[F_SS##PP##XX]{.underline}

where F is the FID (Field Panel)

SS is the system type

\## is the system number

PP is the point type

\## is the point number

XX is any special information

such as SP (setpoint)

VP (virtual point)

\_C (Critical Alarm)

\_H (High Speed)

\_L (Low Speed)

System type designators are:

AH - Air Handler

BG - Bldg General (control, alarm, etc.)

BR - Boiler HW System

CH - Chiller/CHW system

CV - Steam Converter HW system

CT - Cooling Tower

DX - Direct Expansion Unit

Point Type Designators are:

*Analog Inputs (AI)*

CU - Current

HD - Duct Humidity

HR - Room Humidity

MA - Air Flow Measuring

PR - Pressure

TD - Duct Temperature

TG - Gas Temperature

TR - Room Temperature

TW - Water Temperature

WX - Weather Station

*Analog Outputs (AO)*

ES - Electronic Speed Control (VFD)

FC - Fan Control (blade pitch, inlet vane)

PD - Pneumatic Damper

PV - Pneumatic Valve

PS - Pneumatic Sequencing Control

ED - Electronic Damper Motor

EV - Electronic Valve Operator

*Digital Inputs (DI)*

AA - Miscellaneous Alarms

AB - Boiler Alarms

AC - Chiller Alarms

AH - Humidity Alarm

AL -Level Alarm

AP - Pressure Alarm

AT - Temperature Alarm

AV - Vibration Alarm

ME - Electric Pulse Meter

MG - Gas Pulse Meter

MS - Steam Pulse Meter

MW - Water Pulse Meter

ST - Equipment Status

*Digital Outputs (DO)*

SS - Start/Stop or On/Off Control

SANDIA LCTLR POINT DESCRIPTORS

The Landis & Staefa Powers product line includes Local Area Network
devices that can be attached to LAN trunks terminated at L&G Powers
Field Panels (MBC, SCU, LAN Controller.) Points reside in LAN devices in
EEPROM and have a canned program according to the defined application of
the device. These LAN device-resident points are not visible to the
operator in the same manner as points residing in field panels, but they
can be displayed in two ways:

1\. Each LAN device is defined in the home field panel's database as an
LCTLR point. The LAN-resident points can be viewed via a subpoint log
but cannot be displayed on an Insight For PC graphic.

2\. LAN-resident points can be unbundled by creating a point in the
field panel's database with the same address as the LAN-resident
subpoint. This requires additional field panel memory but permits
viewing via Insight For PC graphic.

The following standards are established for descriptors of LCTLR and
unbundled LAN points:

Terminal Equipment Controller LCTLR point descriptor

[B 2072BV155B]{.underline} where:

B is the FID designator in which the LAN device's trunk is attached

2072B is the location (e.g., room number) of the LAN device.

V is the type of LAN device (See table.)

155B is the identifier (e.g., application, address) of the LAN device.
