DX-9100 Extended Digital Plant Controller

Introduction

This document covers all three versions of the DX-9100 Extended Digital Controller, including the DX-912x LONW

Version 1 – provides up to eight output modules, which are configured to

give two analog outputs and six digital outputs (triacs).

Version 2 – provides six additional analog output modules, giving a total

of eight analog outputs.

Version 3 – the DX-912x L

communication to the feature set of the Version 2 controller, and enhanced alarm reporting capability when used as an integral part of an Building Automation System (BAS).

In this document, BAS is a generic term, which refers to the Metasys® Network, Companion™, and Facilitator™ supervisory systems. The specific system names are used when referring to system-specific applications.

The DX-9100 is the ideal digital control solution for multiple chiller or boiler plant control applications, for the Heating, Ventilating, and Air Conditioning (HVAC) process of air handling units or for distributed lighting and related electrical equipment control applications. It provides precise Direct Digital Control (DDC) as well as programmed logic control.

ONWORKS

version brings peer-to-peer

® version. They include:

ORKS

In a standalone configuration, the DX-9100 Controller has both the hardware and software flexibility to adapt to the variety of control processes found in its targeted applications. Along with its outstanding control flexibility, the controller can expand its input and output point capability by communicating with I/O Extension Modules on an expansion bus, and provides monitoring and control for all connected points via its built-in Light-Emitting Display (LED). Versions 1 and 2 can communicate on the N2 Bus as well as on the System 91 Bus*, providing point control to the full BAS Network or to the N30 system or Companion/Facilitator System. The Version 3 controller uses the LONW of the Metasys Control Module (NCM311 or NCM361 in Europe, NCM300 or NCM350 elsewhere) in place of the N2 Bus.

*The terms System 91 Bus and Metasys Control Station are not used in North America.

Configuration Guides—DX-9100 Configuration Guide

(Echelon®) N2 Bus

ORKS

The DX-9100 has two packaging styles. In Version 1, all terminals for field wiring are located within the controller enclosure. Versions 2 and 3 require a separate field wiring mounting base or cabinet door mounting frame, which enables all field wiring to be completed before the controller is installed.

Figure 2: DX-9100-8454 (Version 2)/DX-912x-8454 (Version 3)

with Mounting Base

Note: The mounting base differs for DX-9120 and DX-9121.

Configuration Guides—DX-9100 Configuration Guide

The DX-9100 processes the analog and digital input signals it receives, using twelve multi-purpose programmable function modules, a software implemented Programmable Logic Controller (PLC), time schedule modules, and optimal start/stop modules; producing the required outputs (depending on the module configuration), operating parameters, and programmed logic.

Configuration of all versions of the DX-9100 Controller are achieved by using a Personal Computer (PC) with GX-9100 Graphic Configuration Software (Version 5 or later) supplied by Johnson Controls. Changes to the configuration can be made by using an SX-9120 Service Module (Version 3.1 or later).

Versions 1 and 2 (N2 Bus)

Version 3 (L

ONWORKS

N2 Bus)

The DX-9100 unit (Versions 1 and 2) has two communication links. One is called the N2 Bus or Bus 91 (the term Bus 91 is not used in North America) and is used to interface to a supervisory unit. The other link is called the XT Bus and is used to expand the DX-9100 input/output capability by interfacing up to eight XT-9100 or XTM-905 extension modules. The DX-9100 input/output can be extended by up to 64 remote input/outputs, analog or digital, depending on the type of the connected extension modules and XP expansion modules.

Point connections are made on XP modules, which are monitored and controlled by the XT-9100 or XTM-905 modules. For more details, refer to the XT-9100 Technical Bulletin in the System 9100 Manual (FAN 636.4 or 1628.4). One XP module can provide either eight analog points or eight digital points. Two XP modules connected to one extension module provides eight analog and eight digital points, or sixteen digital points.

Version 1 or 2 of the DX-9100 can be used as a standalone controller or it can be connected to a BAS through the RS-485 serial communications bus (N2 Bus or Bus 91).

Version 3 of the controller (DX-912x-8454) brings peer-to-peer communication to the feature set of the Version 2 controller, and enhanced alarm reporting capability when used as an integral part of a Metasys BAS Network.

The new communications features are provided by the L

ONWORKS

Network, which enables Version 3 controllers to pass data from one to another and to send event-initiated data to the NCM350 (NCM361 in Europe) Network Control Module, in the BAS. The L

ONWORKS

(Echelon) N2 Bus is used in place of the N2 Bus, and the NCM300 or NCM350 (NCM311 or NCM361 in Europe) must be fitted with a L

ONWORKS

(Echelon) driver card.

The Version 3 controller retains all the input/output point and control capabilities of the Version 2 controller, including the point expansion feature using extension modules and expansion modules.

Configuration Guides—DX-9100 Configuration Guide

In addition to the Version 2 features, the Version 3 controller has network input and output points, which can be configured to transmit and receive data over the LONW

Bus. Each controller may have up to 16 network

ORKS

analog input modules, 16 network analog output modules, 8 network digital input modules, and 8 network digital output modules. While network analog input and output modules each contain a single analog value, the network digital input and output modules each contain 16 digital states, which are transmitted as a block between controllers. The transmission of point data is managed by the LONW

Network and is

ORKS

independent of the supervisory functions of the BAS Network Control Module (NCM). A network of Version 3 controllers can be installed to share analog and digital data between controllers on a peer-to-peer basis; a Network Control Module is not required unless the network is to be supervised by a BAS.

Complex control strategies may now be performed in multiple DX-912x controllers without the need for network data exchange routines in a supervisory controller. Applications include the control of multiple, interdependent air handling units, and large hot water or chilled water generating plants with components distributed in various locations within the building.

Configuration Guides—DX-9100 Configuration Guide

Analog Input Configuration

The DX-9100 Controller can accept up to eight analog inputs, which are active (voltage or current) or passive (RTD). Each analog input is defined and configured by the following parameters:

• User Name and Description (GX only)

• Input Signal/Range

• Measurement Units

• Enable Square Root

• Alarm on Unfiltered Value

• Alarm Limits

• Filter Time Constant

AI: Input Signal and Ranging

User Name and Description

Via the GX Tool

To assign the input as active or passive, position the cursor on the appropriate box and double-click the left mouse button. Then position the cursor accordingly and click the left mouse button once to select either Active or Passive.

Select AIn using the right mouse button. Then select Data in the module menu, and enter as appropriate:

User Name (maximum 8 characters)

Description (maximum 24 characters)

For active inputs, at the Type of Active Input field, enter:

0 = 0-10 VDC

1 = 4-20 mA

2 = 0-20 mA

Configuration Guides—DX-9100 Configuration Guide

Each analog input module performs the conversion of the input signal to a variable numeric value expressed in engineering units obtained using the high range and low range.

High Range (HR) = Enter the equivalent number for reading at

high signal input (10 V, 20 mA)

Low Range (LR) = Enter the reading at low signal input

(0 V, 0 mA, 4 mA)

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

where: PR% = analog value in % of physical input signal

For passive inputs at the Type of Passive Input field, enter:

1 = Ni1000 (Johnson Controls characteristic)

2 = Ni1000 Extended Temperature Range (Johnson Controls

characteristic)

3 = A99 (Johnson Controls characteristic)*

4 = Pt1000 (DIN characteristic)

5 = Ni1000 (L. & G. characteristic) (Firmware, Version 1.1 or later)

6 = Ni1000 (DIN characteristic) (Firmware, Version 1.1 or later)

*Note: The North American Johnson Controls silicon sensors

(TE-6000 series) have very similar characteristics to the A99 sensor. At 21°C (70°F) and 25°C (77°F) the reference values are identical. At -40°C (-40°F), the reading will be 0.8°C (1.5°F) high. At 38°C (100°F), the reading will be 0.3°C (0.5°F) high.

For Resistance Temperature Device (RTD) inputs, the range of the displayed value is fixed according to the type of sensor. The high/low range entries will not have any effect on the actual sensor readout. The configured high and low ranges determine the control range of any control module to which it is connected. (The difference between the High Range value and the Low Range value is equivalent to a proportional band of 100%.)

At the High/Low control range field, enter the required value:

For active inputs, the analog input module performs the conversion of the input signal to a variable numeric value expressed in engineering units obtained using the high range at Item HRn (RI.01) and low range at Item LRn (RI.02).

For RTD passive inputs, the range of the displayed value is fixed according to the type of sensor. The configured range determines the control range of any control module to which it is connected.

Via the GX Tool

To choose between Celsius and Fahrenheit for active and passive sensors, select Edit-Global Data. Under Temperature Units, select Celsius or Fahrenheit.

Configuration Guides—DX-9100 Configuration Guide

To set the measurement units for active sensors, select the AIn module, and then Data to call up the Data Window. Enter in the Measurement Units field:

0 = None

1 = Temperature (C or F as entered under Edit-Global Data)

2 = Percent (%) (Version 1 only)

In a Version 1 controller the units are displayed on the front panel of the controller as °t, %, or none.

Via the SX Tool

Under Analog Inputs, configure Item AITn (RI.00). The measurement and temperature units of each analog input can be selected with the following bits (low byte):

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 (Version 1 only)

AI: Enable Square Root

For RTD sensor inputs, Celsius and Fahrenheit units must be selected. Changing individual units for each AI can only be done via 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 and is only available for active sensors.

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

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

Via the GX Tool (option only available with active sensor)

Select AIn. Then select Data in the module menu. At the Square Root field, enter 0 to disable the square root function, or 1 to enable the square root function.

Via the SX Tool

Under Analog Inputs, configure Item AITn (RI.00) (low byte):

X5 = 1 Enable Square Root of Input

X5 = 0 Disable Square Root of Input

AI: Alarm on Unfiltered Value

An alarm from the High Limit and Low Limit Alarm values will be generated from the unfiltered input.

Configuration Guides—DX-9100 Configuration Guide

Via the GX Tool

Select AIn. Then select Data in the module menu. At the Alarm Unfiltered field, enter 0 to set an alarm on a filtered value, or 1 to set an alarm on an unfiltered value.

Via the SX Tool

Under Analog Inputs, configure Item AITn (RI.00) (low byte):

X6 = 1 Alarm on Unfiltered Value

X6 = 0 Alarm on Filtered Value

AI: Alarm Limits

The high limit and the low limit define at which levels the analog input reading will generate an alarm, either for remote monitoring or for internal use within the control sequences in the DX-9100. A limit differential defines when a point comes out of alarm.

Note: The limits cannot be deleted. If you do not want alarms, enter

limits beyond the high/low range of the sensor.

Configuration Guides—DX-9100 Configuration Guide

The low limit and high limit alarm processing can be disabled. In the menu bar, select Edit-Add Alarm Disable. The corresponding module (box) will appear on screen. Make connections as described earlier under

Configuration Tools - Making Connections.

Note: The Alarm Disable feature is sometimes referred to as Auto

Shutdown in the BAS.

Via the SX Tool

Under Analog Inputs, the alarm limits differential is adjustable with Item ADFn (RI.06). The high limit is at Item HIAn (RI.03), the low limit is at Item LOAn (RI.04).

The low and high limit alarm processing can be disabled by making a logical connection to Item ALD@ - Alarm Disable Condition Source (General Module RI.31).

For Both SX and GX

When the logic signal connected to ALD@ or Alarm Disable Condition Source is true (1), alarm states on analog inputs will be frozen until the logical signal returns to false (0). (Alarm states on analog inputs to XT modules are not frozen by the ALD@ connection.)

AI: Filter Time Constant

AI Notes

The Filter Time Constant Ts (seconds) is used to filter out any cyclic instability in the analog input signals. The calculations are:

FVt = FV

Where: FV

Via the GX Tool

+ [1/(1 + Ts)] * (AIt - FV

t-1

= Filtered Analog Value at current time

= Filtered Analog Value at previous poll

t-1

= Actual Analog Value at current time

t-1

)

Select AIn. Then select Data in the module menu. At the Filter Constant (sec) field, enter a number within the recommended range 0 to 10.

Via the SX Tool

Under Analog Inputs, the Filter Time Constant is selected at Item FTCn (RI.05).

1. You can read the AI values, and read and modify the alarm limit values using the DX front panel. See Display Panel and Keypads in the DX-9100 Extended Digital Controller Technical Bulletin (LIT-6364020) in FAN 636.4 or 1628.4.

Configuration Guides—DX-9100 Configuration Guide

2. The alarm condition of one or more analog inputs is also indicated by an LED (AL) on the front panel. If the LED is steady, the current AI is in alarm; if flashing, another AI is in alarm.

3. Using the SX Tool, analog input values can be read at Analog Inputs Item AIn (RI.07), and the percent of range value can be read at Item AI%n (RI.08). The value as an ADC count can be read at Item ADCn (RI.09).

4. Using the SX Tool, analog input alarm statuses can be read at General Module Item AIS (RI.07), or at Analog Input Item AISTn (RI.10), where bits X1 and X2 indicate the high and low alarm conditions, respectively.

5. Under Analog Inputs, the analog Item AISTn (RI.10), bits X3 and X4, indicate an input over-range (input about 2% of range above HR) condition and an input under-range (input about 2% of range below LR) condition, respectively. (This information is available on the SX Tool only.)

6. Calibration coefficients for active and passive analog inputs are stored in the EEPROM of the DX. See the Calibration Values section further in this document.

Digital Input Configuration

The DX-9100 Controller can accept up to eight digital inputs, which will be considered active when driven to a common digital ground by an external volt-free contact. The DI is defined and configured by the following parameters:

• User Name and Description (GX only)

• Prescaler

The digital input transitions are counted as follows:

dxcon006

Figure 6: Digital Input Transitions

The Pulse Counter (CNTRn) counts all state transitions of the bit-Item DICn. A state transition at DICn occurs when the number of transitions from 1 to 0 of DIn Digital Input equals the value of the Prescaler Factor (PCn). For example, if PCn is equal to 1, then every 1 to 0 state transition at the DI will add 1 to CNTRn. If equal to 3, then three changes from 1 to 0 will add 1 to CNTRn. The maximum transition rate of DIn is 10 pulses per second (minimum 50 ms On and 50 ms Off).

Via the GX Tool

Select DIn. Then select Data in the module menu.

At the User Name field, enter the name, which can have a maximum of eight characters.

At the Description field, enter the descriptive text, which can have a maximum of 24 characters.

DI Notes

At the Prescaler (counts) field, enter a number between 1 and 255.

Via the SX Tool

Under General Module, enter the prescaler for each digital input at Items PC1 (RI.22) to PC8 (RI.29).

1. You can read the DI’s status and counter values using the DX front panel. See Display Panel and Keypads in the DX-9100 Extended Digital Controller Technical Bulletin (LIT-6364020) in FAN 636.4 or 1628.4.

2. On the SX Tool, the digital input status (DIn), the count transition status (DICn) and the pulse counter values can be read under General Module at the Items given in Figure 6.

Analog Output Configuration

The DX-9100 Controller has two analog outputs (numbered 1 and 2), controlled by two analog output modules, and six digital (triac) outputs (numbered 3 to 8) controlled by six logic output modules. Versions 2 and 3 of the DX-9100 have an additional six analog outputs (numbered 9 to 14) controlled by six analog output modules.

The analog output module provides the interface between a 0-10 VDC or 0/4-20 mA hardware output and a numeric value scaled to a 0-100% range using a high and low range variable.

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

• user name and description (GX Only)

• type of output

• numeric source

• increase/decrease source (if any)

• low and high ranges

• forcing mode and level

• hold or auto on power up

• output limits, enable limits

AO: Output Type

Via the GX Tool

Select AOn. Then select Data in the module menu. At the field User Name, enter the name.

At the Description field, enter the description.

Then enter the output code:

0 = Disabled

1 = 0 to 10 VDC

2 = 0 to 20 mA (not available for Outputs 11-14)

3 = 4 to 20 mA (not available for Output 11-14)

Configuration Guides—DX-9100 Configuration Guide

Via the SX Tool

Under Output Modules, the output type can be configured in Item AOTn (RI.00). To define the output signal set the bits as follows:

X2 X1 = 00 Output Disabled

X2 X1 = 01 Output 0-10 V

X2 X1 = 10 Output 0-20 mA (not available for Outputs 11-14)

X2 X1 = 11 Output 4-20 mA (not available for Outputs 11-14)

AO: Source

This defines the source of the numeric control signal that drives the output module. The output module can, alternatively, have two logic sources: the source of the increase signal and the source of the decrease signal. The rate of increase or decrease is fixed at 1% per second.

Via the GX Tool

Expand both source and AOn modules. Place the mouse on the source point. Hold down the left mouse button and drag the cursor to the center of AO@. The connection will be made when the mouse button is released.

If logic variables (Increase/Decrease) are used as a source to drive the analog output, then the source module and AOn module must be expanded as described above. Place the cursor on the logic source point. Press the mouse button and while keeping it pressed, drag the cursor to INC@ in the AOn module. Release the mouse button to make the connection. Repeat the same procedure for the DEC@ connection.

Via the SX Tool

Under Output Modules, Item AO@n (RI.01) defines the source of the numeric control signal. Alternatively, the source of the increase signal is defined in Item INC@n (RI.10), and the source of the decrease signal is defined in Item DEC@n (RI.11).

AO: Forcing Mode and Level

This defines the source of a logic variable that forces the Analog Output to a forcing level between 0 and 100%. When the logic source is 1, the AO will be forced to the % entered in Forcing Level. When the logic source is 0, the AO will be commanded to position via the source point.

Note: If a PID is connected to the AO and the AO is forced, the PID will

experience force-back, which means the PID is also in Hold mode at this time and its output is forced to the value of the analog output.

Configuration Guides—DX-9100 Configuration Guide

Via the GX Tool

Select AOn. Then select Data in the module menu. At the Forcing Level (%) = field, enter a number between 0 and 100%.

Double-click on AOn to expand the module. Double-click on the source module. Place the cursor on the logic source point. Press the mouse button and while keeping it pressed, drag the cursor to AOF@. Release the mouse button to make the connection.

Via the SX Tool

Under Output Modules, Item AOF@n (RI.02) defines the source of a logic variable that forces the output to the forcing level, which is defined in Item OFLn (RI.05).

AO: Hold or Auto On Power Up

Upon power restoration, the AO can optionally be forced to a Hold (Manual) or Auto (Hold reset) condition, irrespective of the Hold condition before the power failure and overriding the Initialization on Power Up setting for the controller and overrides sent from the front panel or BAS.

Via the GX Tool

Select AIn. Then select Data in the module menu. Then enter 1 for the appropriate power up condition, if required:

Hold on Power Up = (1 = Yes)

Auto on Power Up = (1= Yes)

If both Hold and Auto are enabled, Hold has higher priority. If both are disabled, the current setting under the Initialization on Power Up field determines the output.

Via the SX Tool

Under Output Modules, set bits X7 and X8 of Item AOTn (RI.00) as follows:

bit X8 = 0 The Hold mode is not altered after a power failure.

bit X8 = 1 The Hold mode is set at power up to the status set in bit X7.

bit X7 = 0 The Hold mode is set to hold at power up if bit X8 is set.

bit X7 = 1 The Hold mode is reset (set to 0) at power up if bit X8 is set.

Configuration Guides—DX-9100 Configuration Guide

AO: Range

The High Range Item (HRO) defines the level of the control source signal (AOn), which would correspond to an output of 100%.

The Low Range Item (LRO) defines the level of the control source signal (AOn), which would correspond to an output of 0%.

If LROn < AOn < HROn OUTn = 100 * (AOn - LROn)/(HROn -

LROn)%

If AOn <= LROn OUTn = 0% (0 V, 0/4 mA)

If AOn >= HROn OUTn = 100% (10 V, 20 mA)

When the source point is equal to the high range, then the output will be at the maximum signal (10 V/20 mA). When the source point is equal to low range, then the output will be at the minimum signal (0V, 0/4 mA).

Via the GX Tool

Select AIn. Then select Data in the module menu. At the High Range and Low Range fields, enter the appropriate numbers within the range of the source signal:

High Range =

AO: Output Limits, Enable Limits

Low Range =

Via the SX Tool

Under Output Modules, set the High Range at Item HROn (RI.03) and the Low Range at Item LRO (RI.04).

The output high limit defines the maximum output in percent. The output low limit defines the minimum output in percent. These limits are enabled by a logic connection and are only operative when the logic source is at 1.

When the limits are enabled:

If OUTn > HLOn

OUTn = HLOn

If OUTn < LLOn

OUTn = LLOn

Configuration Guides—DX-9100 Configuration Guide

Via the GX Tool

Select AOn. Then select Data in the module menu. At the High Limit % and Low Limit % fields, enter the desired number (0-100%). For Enable Limits, expand both source and AOn modules. Position the cursor on the source point. Press the mouse button, and while keeping it pressed, drag the cursor to ENL@. Release the mouse button to make the connection.

Via the SX Tool

Under Output Modules, set the following:

High Limit on Output = Item HLOn (RI.08)

Low Limit on Output = Item LLOn (RI.09)

The limits are enabled by a logic connection to Item ENL@n (RI.12).

AO Notes

1. The AO can be read and overridden (placed in hold) from the DX front panel. See Display Panel and Keypads in the DX-9100 Extended

Digital Controller Technical Bulletin (LIT-6364020) in FAN 636.4 or

1628.4.

2. On the SX Tool, the analog output values can be read in percent at Item OUTn (RI.06) and can be modified when the module is in Hold mode.

3. On the SX Tool, Analog output control and status can be seen at Item AOCn (RI.07) in the following bits:

X1 = 1 OUHn Output in Hold mode (Manual)

X2 = 1 AOHn Output at High Limit ... 100%

X3 = 1 AOLn Output at Low Limit ... 0%

X4 = 1 AOFn Output is Forced

X6 = 1 OULn Output is Locked (Both INC@n and DEC@n

are true)

4. The analog output module can be set in Hold on the DX front panel or by the PLC, the SX Tool, a BAS, or by configuration on power up.
