XT-9100 Extension Module/
XP-910x Expansion Modules

Introduction

The XT-9100 Extension Module and its expansion modules have been
designed to provide additional input and output capacity within Metasys
Networks and specifically for the DX-9100 Extended Digital Controller.
The XT-9100 module provides the communication interface and the
XP modules provide the analog and digital inputs and outputs.

A Supervisory System communicates with an XT-9100 via the N2 Bus or
Bus 91*. Each XT-9100, depending on its expansion module combination,
can have up to 16 inputs/outputs, eight of which may be analog.

The DX-9100 communicates with the XT-9100 via the XT-Bus, and when
the DX-9100 is connected to an N2 Bus (or Bus 91), data from the
XT-9100 is available to a Supervisory System. Up to eight XT-9100
modules can be connected to the XT-Bus. Each XT-9100 provides,
depending on the type of the connected XP expansion modules, either
eight analog points or eight digital points, extending the input/output of a
DX-9100 by up to 64 remote input/outputs. Modules with 16
input/outputs may also be connected, provided that the total number of
remote input/output points on the DX-9100 does not exceed 64.

Configuration of the XT-9100 is achieved by using a personal computer
with GX-9100 Graphic Configuration Software (GX Tool) supplied by
Johnson Controls. When the serial interface of the XT-9100 is connected
directly to the N2 Bus (Bus 91), the GX-9100 will download and upload
configurations over the N2 Bus (Bus 91). When the serial interface of the
XT-9100 is connected to the XT Bus, the GX-9100 will download and
upload configurations via the N2 Bus (Bus 91) connected to the DX-9100
to which the XT-Bus is connected. The DX-9100 retransmits
configuration data to the XT-9100 on its XT-Bus.

Hardware
Configuration

For full details of the hardware configuration, refer to the XT-9100
Technical Bulletin (LIT-6364040).

An XT-9100 combined with expansion modules provides the following
configurations, either:

• eight analog inputs/outputs, or

• eight digital inputs/outputs, with digital counters associated with the

digital inputs, or

• eight analog inputs/outputs and eight digital inputs/outputs, or

• sixteen digital inputs/outputs, with digital counters associated with the

digital inputs within the first eight inputs/output points

The extension module address is set with the address switches on the
XT-9100. When connected to a DX-9100 controller, this address must
also be set in the DX-9100 software configuration. The address must be
unique not only on the XT-Bus, but also on the N2 Bus (Bus 91) to which
the DX-9100 is connected.

The XT-9100 must be supplied with a 24 VAC power source. All models
are suitable for 50 Hz or 60 Hz through software configuration.

For the analog inputs and outputs, the input and output type are set by
jumpers on the analog expansion module board. These settings must
comply with the software configuration settings.

Model Codes

Note: When an extension module is configured with 16 inputs/outputs,

the DX-9100 considers the single physical module as two logical
modules, each with eight inputs/outputs. A DX-9100 can
communicate with up to eight logical modules, with a maximum of
64 inputs/outputs.

XT-9100 Type
Settings

Software Configuration

Software configuration involves the setting of all the Items of the
extension module to values which correspond to the intended application.
Typically, use the GX Tool to configure a system, and the SX Tool to
troubleshoot. To use these tools, refer to the GX-9100 Software

Configuration Tool for Windows User’s Guide (LIT-6364060) and the
SX-9100 Service Module User’s Guide (LIT-6364070). Proceed in the

following order:

1. Define XT-9100 type settings.

2. Define XT-9100 configuration.

3. Define analog input characteristics.

4. Define digital input characteristics.

5. Define analog output characteristics.

6. Define digital output characteristics.

Power Line
Frequency
(50 or 60 Hz)

Output
Hold/Reset on
Comm. Failure
Flag

Via the GX Tool

Select DX-9100 and then Global. Enter the frequency as 50 or 60. The
XT frequency and the DX frequency are both defined here.

Via the SX Tool

Set Bit X1 of Item XTS (RI.69).

X1 = 0 50 Hz power line
X1 = 1 60 Hz power line

Via the GX Tool

First configure an XT Module. Select XTn, then Analog or Digital. Then
select the just configured XTn, XTn, and Data.

To set this flag, at the “Status on comm. fail” (communication failure)
field, enter 0 or 1.

When this bit is set to “0,” the digital outputs are switched off upon a
serial interface failure, and the corresponding Item values are reset to zero.

When set to “1,” the digital outputs hold their current state upon a serial
interface failure.

Configuration Guides—XT-9100 Configuration Guide 7

Via the SX Tool

The “Output Hold/Reset on Communication Failure” flag is set at Bit X2
of Item XTS (RI.69).

X2 = 0 Output reset upon communication failure
X2 = 1 Output hold upon communication failure

Maximum Time

Communications

Operational Mode
(SX Only)

When communication fails for the period set in this Item, the XT-9100
goes into “communication failure” state, indicated by a blinking power
LED on the front of the module. The default value is 60 seconds.

Via the GX Tool

First configure an XT Module. Select XTn, then Analog or Digital. Then
select the just configured XTn, XTn, and Data. At the “Comm. timeout
(sec)” field, enter the value in seconds.

Via the SX Tool

The “Maximum Time Between Communications” (in seconds) is entered
at Item MTBC (RI.86).

The operational mode of the XT-9100 can be seen at Item OPMO (RI.01)
with following status bits:

X8 = 1 PWR Power Failure. This bit is set when a XT is

powered up or when there is a serial interface
communication failure.

The setting in Item XTS (RI.69) Bit X2 (“Output Hold/Reset on
Communication Failure” flag) is repeated in Item OPMO (RI.01) Bit X7
so that it can be read by the DX-9100 or any other monitoring system.

XT Address

Via the GX Tool

In order to download the XT-9100 devices it is necessary to enter the
XT addresses. These addresses will also be loaded into the DX-9100.
When performing a download through a DX-9100 Controller, the
controller only downloads the addresses of its own XT set. The
XT address is not stored in the XT-9100 but must be set on the address
switches on the module.

First configure an XT Module. Select XTn, then Analog or Digital. Then
select the just configured XTn, XTn, and Data. At the “Hardware
Address” field, enter the address (1-255) of the XT-9100 module.

Via SX Tool

Refer to the Extension Module Configuration section in the DX-9100
Configuration Guide (LIT-6364030).

8 Configuration Guides—XT-9100 Configuration Guide

XT-9100
Configuration

Settings

Via the GX Tool

The I/O type and map details are automatically generated by the GX-9100
Graphic Configuration Software when all I/O data for extension modules
has been entered. It is then downloaded into the XT-9100 directly or via
the DX-9100 and XT-Bus. (Refer to the Download/Upload section,
further in this document.)

When in the GX Tool, select the XT module, then define it as Analog or
Digital (if Digital, define it as 8 DI, 4DI/4DO, or 8DO). This defines
Module XP1. If an XT has 16 points (XP2 is connected), select the
XT box immediately to the right of the configured module, select
EXP.DIG and define it as 8DI, 4DI/4DO, or 8DO. “EXP” will appear in
the XT box. Then select XT (or EXP) again and define each point in the
selected configuration in the same way as when defining the points in the
DX-9100. The following pages describe how to define each of the points
individually.

Via the SX Tool

Each extension module configuration is defined by the I/O types and
map which are configured in Extension Module Items IOMAP (RI.77),
IOTYP (RI.78), and IOMOD (RI.79).

1. The I/O map (IOMAP) defines which inputs/outputs (in pairs) on the

extension module are used. Each extension module can be defined
with eight used points, which normally reside in the XP1 (first)
Expansion Module (points I/O1-I/O8), defined in bits X1-X4.

When an extension module has an XP2 (second) Expansion Module
with a further eight points, these points must be defined in bits X5-X8.

2. The I/O type (IOTYP) defines which inputs/outputs (in pairs) are

analog and which are digital. As the points on XP2 (if used) must be
digital, only bits X1-X4 can be configured.

3. The I/O mode (IOMOD) defines points as “input” or “output”

(in pairs). Only those points declared as “used” in Item IOMAP will
be monitored or controlled.

The combination of data in the Items IOMAP, IOTYP, and IOMOD
completely defines the configuration of an extension module. When
connected to a DX-9100 Controller, an identical set of data must be
entered into the Item data base in the DX-9100 Controller, so that,
when the DX-9100 and XT-9100 are connected and started up, the
DX-9100 will compare data bases and only send commands to the
extension module if the data is identical, thus avoiding incorrect
control actions.

Configuration Guides—XT-9100 Configuration Guide 9

Analog Input

Note: The data base in the XT-9100 has been designed to accept most

configuration of inputs and outputs. All inputs and outputs

which are physically connected through expansion modules
must be configured, and only those points. If there is a

difference between the physical configuration and the software
configuration, the XT-9100 will signal an error condition to the
DX-9100 (XTnERR).

Configuration

Each analog input is defined and configured by the following parameters:

• Tag name (optional, GX-only)

• Measurement units (for RTD inputs)

• Enable square root

• Alarm on unfiltered value

• Input signal range

• Alarm limits

• Filter time constant

The GX Tool determines the input signal range with a 2-stage process:
you must first decide if the input is active or passive; the remaining
options depend on this choice. With the SX Tool, this information is
entered into a number of Items.

Via the GX Tool

Select XTn, AIn, then either Active or Passive.
Note: All AI points must be configured even if not connected to a sensor

to enable the generation of a complete IO Map and to ensure
correct operation with the DX-9100 Controller.

AI Input Type:
Measurement
Units

Via the GX Tool

The selection of Celsius or Fahrenheit, is set in the Global data of the
DX-9100 (select DX-9100, then Global. At the “Temperature Units”
field, enter “C” for Celsius or “F” for Fahrenheit).

To determine the measurement units of active inputs, select XTn, AIn,
Data, and then enter in the “Measurement Units” field:

0 = None
1 = Temperature (“C” or “F” as entered in Global)
2 = Percent (%)

Note: The units of an active input are not read by the DX-9100

Controller, but are available to any other Supervisory System
which may be connected.

10 Configuration Guides—XT-9100 Configuration Guide

Via the SX Tool

The input type for the eight possible inputs (n = 1 to 8) can be configured
in Item AITn (RI.88, RI.96, RI.104, RI.112, RI.120, RI.128, RI.136, and
RI.144).

The unit of each analog input can be selected with following bits: (For
RTD inputs, Celsius or Fahrenheit must be selected.)

X4 X3 X2 X1 = 0000 No Units
X4 X3 X2 X1 = 0001 Celsius
X4 X3 X2 X1 = 0010 Fahrenheit
X4 X3 X2 X1 = 0011 Percent

Changing individual temperature units for each AI can only be done in the
SX Tool.

AI Input Type:
Enable Square
Root

This function allows the linearization of the differential pressure signal
from a 0-10 VDC or 0/4 - 20 mA active sensor; the function is effective
over the selected range:

AI = sqrt(PR%/100) * (HR - LR) + LR

Where %PR = the Analog Value in % of the physical input range;
HR = High Range Value; and LR = Low Range Value.

Via the GX Tool (Option Only Available with Active Sensor)

Select XTn, AIn, and Data. At the “Square Root” field, enter “0” for No,
or “1” for Yes (to enable the square root calculation).

Via the SX Tool (Option Only Available with Active Sensor)

Select Item AITn.

X5 = 1 Enable Square Root of Input
X5 = 0 Disable Square Root of Input

Configuration Guides—XT-9100 Configuration Guide 11

AI Input Type:
Alarm on
Unfiltered Value

An alarm from the High Limit (HIAn) and Low Limit Alarm (LOAn) will
be generated from the unfiltered or filtered input. (See Filter Time
Constant.)

Via the GX Tool

Select XTn, AIn, and Data. At the “Alarm Unfiltered” field, enter “0” for
No (Alarm on Filtered Value), or “1” for Yes (Alarm on Unfiltered
Value).

Via the SX Tool

Select Item AITn.

X6 = 0 Alarm on Filtered Value
X6 = 1 Alarm on Unfiltered Value

AI Input Type:

Range

Via the GX Tool

(You must first have selected whether the input is active or passive. See
the beginning of Analog Input--Configuration.)

For active inputs, select XTn, AIn, then Data. At the “Type of Active
Input” field, enter:

0 = 0-10 VDC
1 = 4-20 mA
2 = 0-20 mA

Each analog input module channel performs the conversion of the input
signal to a numeric value using the high range and low range.

Select XTn, AIn, then Data.
High Range = enter the equivalent number for reading at high input

(10V, 20 mA)

Low Range = Enter the reading at low input (0V, 0 mA, 4 mA)
For passive inputs, select XTn, AIn, then Data. At the “Type of Passive

Input” field, enter:

1 = Ni1000 (JCI Type)
2 = Ni1000 Extended Range
3 = A99 (JCI Type)
4 = Pt 1000 (DIN)

Note: Selections 5 and 6 on the screen are not available in the

XT-9100.

For RTD inputs, the range of the displayed value is fixed according to the
type of sensor.
