IMPORTANT NOTICE

The number of points, files, system objects, entries in a log or array, ex­changed points, and statements you can program are all subject to memory and
system limitations. Controller scan speed is reduced as you increase the num­ber objects defined and amount of communication activity on the network.
Various operations or activities on the system will affect system performance.
You should check the amount of memory available frequently (see the Ando­ver Controls

programmer’s guide s fo r de ta ils ). Consult with your An­dover Controls representative concerning the amount of memory your instal­lation requires.

The volumes present the following:

• Volume 1—Getting Started Programming

• Volume 2—Advanced Programming/Access Control
If you are using the control system for HVAC, you should proceed

through this manual sequentially. If you are using the control system for
access control, begin with Chapter 21 in Volume 2.

If you do not know anything about HVAC, this manual does not provide
adequate information. The examples in it are extremely simplistic for
purposes of illustrating programming techniques and concepts. Fo r

You might find it useful to draw a sketch of the network,
showing each item.

Figure 1-1 shows what a map of a typical network looks like.
You should have a tag that came from each controller, IOU,

reflects the actual layout of the controller system.

Each

controller on that map can have one or more
input output units (IOUs). Each IOU has a number the con­troller identifies it by. That number is marked on the map.

Knowing about Point Types

Input and Output Point

Each IOU on the controller has 32 universal input sensors and
16 outputs, which may be universal, tristate, or Form C (ON
and OFF). The “universal” inputs and outputs accept input
from and send output to several types of sensors or devices
without any hardware alterations.

We refer to all these sensors and transmitters as input and out­put points.

Input and output points are
the environment.

An input point is constantly receiving info rmation about, for
instance, the temperature in a room. While that temperature
remains within a set range (say 68 to 72), the controller takes
no action.

If the heat is off and not needed, the controller does not turn it
on. When the temperature drops below 68 or rises above 72,

Infinity

’s way of interacting with

Rules for Naming Point

the point triggers a response from the controller.
Usually, only when a point changes does the controller take

action. Types of points other than inputs and outputs are de­scribed in Chapter 5.

Plain English Names

The controller cannot act on a point unless you tell it the name
and location of the point. So you must assign a name to each
point.

Points and other items on the controller can be named with up
to 16 alphabetic and numeric characters, including periods
and underscores. The first character must be alphabetic.

You can enter the name in upper and lowercase the first time
so it is more readable than all caps, but the controller under-

1-4 Infinity Controller Programmer’s Guide

Understandi ng Controller Hardware

stands it as the same name in either case. For example, the
controller reads the following two names as the same:

SupplyAir
SUPPLYAIR

The first is obviously easier for you to read. If you enter it that
way the first time, later, even when you enter SUPPLYAIR,
the controller will reprint it on the screen as

SupplyAir

each

time you open the program file.
Procedures to tell the controller the names of all the points are

in Chapter 4.

Locating Controller Points

You might want to make copies of the drawings on the next
few pages, one for each

Infinity CX 9000

IOU and each

Infinet

controller on the network.
The drawings show the input and output points and the nu-

meric labels supplied at by Andover Controls . In your
drawing, you write a name next to each input and output that
defines its purpose. Note which IOUs are tristate, universal, or
Form C.

You can later follow these drawings when setting up points.
If you have many IOUs connected to one
a great many

Infinet

controllers, these drawings may help

avoid confusion.

For this special controller, you do not set up ordinary points.
Instead, you set up Doors, as described in Chapters 21, 22,
and 23 of Volume 2. Doors are similar to points. Each door
has a channel number. Door1 is channel 1, Door2 channel 2.
You can also connect a door to Output 3 (channel 3).

You do not set up the card readers or keypads as input points,
but associate a card reader or keypad with a particular door by
assigning the channel number (Reader1 is channel 1, Reader2
is channel 2) to the card reader for the particular door.

You can, in addition, set up the supervisory inputs as input
points. For information about the types of sensor s you can
wire to supervisory inputs, and for more information about
Doors and access control, see Chapters 21, 22, and 23. Refer

to Chapter 4 for how to set up supervisory point types.

and 8.

The two knobs adjust the two outputs between 0 and 20 V.
You can set the override switch to manual or automatic. You

cannot, however, get feedback through the controller telling
you that either of these outputs is set to manual control with
the OVERRIDE switch or telling what the override setting is.

Figure 1-14 is a drawing of an

module. This module
has two analog outputs that must be controlled by the
controller because they have no manual override switches.

You can use one or two modules of this type in a single chain.
