DX-9100 Digital Controller, Version 1

The DX-9100 Digital Controller is the ideal digitalcontrol solution for multiple chiller or boiler plantcontrol applications, for the HVAC process of airhandling units or for distributed lighting and relatedelectrical equipment control applications.

As a standalone controller, the DX has both thehardware and software flexibility to adapt to thevariety of control processes found in its targetedapplications. Along with its outstanding controlflexibility, the controller can extend its input andoutput point capability by communicating withinput/output (I/O) extension modules on anextension bus, and provides monitoring and controlof all connected points at its built-in LED display.

When integrated into a full Metasys network,point and control information is availablethroughout the network, and at all Metasysoperator workstations.

E xtension ModulesThe extension (XT and XTM) and expansion(XP) modules may be mounted next to thecontroller on the same DIN rail, or remotely, upto 1200 m from the controller.

An extension module set is assembled fromsubmodules, providing various combinations ofanalog and digital (binary) I/O points. Up to eight

extension modules can be connected to thecontroller via the RS-485 extension bus..

The XTM extension module and its expansionmodules provide a wider and more flexible rangeof I/O options as well as a manual overrideoption on outputs.

S ensors and Actuators to Complete the SystemThe DX Controller and extension modules arematched to a family of sensors, actuators,control valves, and dampers needed to completethe control of chiller and boiler plants, HVACprocesses and other refrigeration and heatingapplications. Its sensor inputs can accept 0-10Vtransmitters and passive temperature sensorsfrom the Johnson Controls range, as well as

industry standard 4-20mA transmitters. Outputsare available to control both proportional andincremental electric actuators, as well as motorcontrol relays, staged heating and cooling andother electrical equipment such as lightingcontrol relays. Pneumatic actuators may becontrolled by the use of an external transducer.

C onvenient Configuration SetupThe DX-9100 Digital Controller does not need tobe programmed in the traditional sense. Instead,the control algorithms, time programs andinput/output point assignments are configuredwith the use of a Graphic Configuration Tool,which runs under the Microsoft Windowsoperating system. The graphic software isinstalled on a laptop computer which isconnected to the controller’s N2 Bus for loadingthe controller’s configuration.

Program data and parameters loaded into thecontroller and into the extension modules arestored in EEPROM, so there is no need to reloadsoftware after a loss of power. Real time andoperating data in the controller are stored inbattery backed RAM.

Configuring a controller and its extensionmodules is a simple matter of selecting desiredmodule types to form a flow chart diagram,connecting inputs to control and logic blocks,and closing the control loop by making theconnection from the control and logic blocks tothe outputs. As the flow chart is being filled in,the set point parameters, gains, alarm limits,start and stop times, etc., are added to thecontrol and logic blocks and inputs and outputsto complete the configuration. Names may beentered for inputs, outputs and operatingparameters for documentation purposes and forelectronic transfer to the Metasys Workstationdata file.

B uilt-in Display PanelOnce the controller and its extension modulesare configured, the operating parameters andinput/output values can be seen at the displaypanel built into the controller. Outputs can bemanually overridden and operating parametersmay be changed by an operator who hasplugged his security key into the controller. Thesame information viewed on the face of thecontroller can be displayed and changed fromany of the Metasys operator devices, or from theGraphic Configuration Tool when in onlinecommissioning mode.

A pplication VersatilityThe DX-9100 Digital Controller can beconfigured to meet a wide variety of basic HVACand multiple boiler or chiller central plantapplications. Configurations may be pre-configured for common applications to use as afoundation to customize your particular needs. Ifthe pre-configured examples don’t cover yourneeds, you can start with a blank flow charttemplate on the Graphic Configuration Tool, andconfigure a totally customized process to meetyour specific application requirements.

In addition, points unused in the controlapplication can be used for supplementarysupervisory purposes by the Metasys network.

N etworking CapabilitiesAs powerful as the DX-9100 Digital Controller isby itself or with extension modules, your facilitywill benefit even more when controllers are partof a larger Metasys network. A Metasys NetworkController Module (NCM) can be programmed toprovide added energy management andsupervisory control capabilities, such as trendlog, historical data storage, electrical demandlimiting and more. In remote locations, the trendlog data in the controller can be transferred tothe central Metasys network by a switchedtelephone line connection.

The Metasys Dynamic Data Access networkingsoftware, available from the Network ControllerModule, makes information from each controlleravailable throughout the facility, so that it ispossible, for example, to reset the boiler orchiller discharge temperature set point based onthe demand requirements of a group of terminalunit controllers. Dynamic Data Access alsomakes sensor values, operating status, andother parameters in the controller available tooperators anywhere in your facility.

P recise, Flexible ControlThe DX Controller represents the best way tofully optimize the operation of your refrigeration,heating, HVAC or lighting equipment controlapplications. It can be used as a member of thefully integrated Metasys system, or as astandalone controller. It combines ease of setupand operation, flexibility of application, andprecise control for comfort and energymanagement.

P assword Protection ofConfigurationsThe DX Controller has an optional feature toprevent unauthorized access to its softwareconfiguration. When a configuration is loaded bythe Graphic Configuration Tool with a user-defined password, it cannot be uploaded byanother tool unless the password is entered.

This feature has been designed to protectstandard configurations of OEM (OriginalEquipment Manufacturer) users.
