XT-9100 Extension Module/

XP-910x Expansion Modules

 

 

 

 

 

The XT-9100 Extension Module and its expansion modules have been

Introduction

 

 

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

Model Codes

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.

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.

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.

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.

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

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.

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).

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.

Units

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).

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.

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.

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.

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

Range

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

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.
