NetController

This manual describes the installation, care and use of the Andover Continuum

NetController CPU module.

The Continuum NetController CPU module is part of the Continuum network-based

intelligent building system. The Continuum system allows you to cost-effectively mix andmatch DIN rail-mounted CPU, power supply, and various combinations of I/O modulesand user interfaces to meet your control and monitoring needs. This CPU includes animpressive array of features.

The Continuum NetController with FLASH EPROM is the high-powered CentralProcessing Unit (CPU) module and network manager for the Continuum intelligentbuilding system.

High-Speed Communications

The NetController acts as the system coordinator for the Continuum I/O modules,providing integrated global control and monitoring, history logging, local and remotealarming. It communicates with the I/O modules via LON communications and a choice ofRS-485 or free topology bus media. In addition, an optional network support interfaceallows the NetController to communicate with other NetControllers and Continuum Workstations over a high-speed 10Mb/s Ethernet Local Area Network (LAN) or a4/16Mb/s Token Ring Network using the TCP/IP protocol. Several different Ethernet

physical interface modules are available ⎯ you can choose either a 10BASE-T (twistedpair), or a10BASE-FL (fiber optic connection).

Flash MemoryNetController’s flash EPROM allows you to download software revisions over network orstandard telephone lines using a Continuum workstation. This flash memory featureeliminates the need to perform EPROM change-outs in the field.

Serial Communications

NetController’s programmable communications ports can be configured as either anRS-232 or an RS-485 interface to modems, printers, third-party devices, and the Infinity Infinet field bus network. TAC has developed an extensive library of third-party softwareinterfaces, including tie-ins to chiller control panels, fire alarm systems, emergencygenerator systems, bar code readers, elevator controls, and video switchers.

Plain Englis h ®

Programming

The Continuum NetController can be configured to meet the exact requirements of yourapplication using the powerful Plain English programming language. Programs areentered into NetController using the Continuum Workstation. The program is then storedin, and executed by, the NetController. (See also the Plain English Language Reference,30-3001-872.)

Software Capabilities

The dynamic memory of the Continuum NetController can be allocated for anycombination of programs, scheduling, alarming, reporting and data logging. Our object-oriented Plain English language with intuitive keywords provides easy operation and

programming. In addition, Plain English ‘s pre-defined and customized functions andpowerful math capabilities reduce programming time for repetitive applications.

Optional Auto-Baud Modem

The optional Continuum modem allows NetController to communicate and exchange dataover standard voice grade telephone lines with speeds up to 33.6K baud. The modemhas built-in data compression and error-correction protocols, auto-dial/auto-answercapabilities, and is UPS-supported.

UPS Operation

The Continuum NetController incorporates software programmable battery backup thatreduces or eliminates the impact of power failure. On UPS, the NetController CPU can turnoff I/O power to extend battery life and support modem and network operation for up to fourhours. In addition, NetController can go into a low-power mode in which only the DRAM andreal-time clock are powered for up to 72 hours.

In smoke and access control installations (UL 864 and UL 294) the listing specifies thatbattery backup is provided for the retention of program memory only.

Modular Design for Snap-Together Connection

NetController features a sleek, lightweight casing designed for natural convection cooling.

Built-in connectors on either side of the NetController module allow power transmissionfrom the power supply module and communication signals to the Continuum I/O modulesto feed through easy snap-together connections. Built-in quick-release fasteners at the

back of the module are provided for DIN rail mounting ⎯ no tools required. Thesefasteners also snap into a locked position for panel mounting.

Mechanical Installation

Note to the installer:This device must be properly installed to suit its intended application.

European Installations:The NetController is listed as a Class 1 device intended for installation in anIP2 enclosure. The Continuum Enclosure is an IP2 enclosure.

When installing I/O modules it is imperative that the installer supply a solid Earthground connection to the module. Refer to the Earth Ground Connection subsectionfound later in this manual.

The NetController module can be mounted to a standard DIN rail or be directlymounted to a panel using screws. Hardware facilitating both mounting methods isincluded as an integral part of the case design.

On the back of each module are molded DIN rail guide fingers. The design allows themodule to easily hook onto and slide along a standard DIN rail.



14/76

Special clamps are provided on the case that allow you to lock the module in place,once it is in position.

These clamps, when extended, provide an alternative method of mounting to the DINrail. You can mount the module directly to a panel using the reinforced mountingholes provided on each of the clamps.

Once the module is in the desired position, it is locked to the rail by pushing thebottom clamps inward. After the bottom is secure, press the top clamp inward tocomplete the operation.

DC Power Connection

PowerConnector

The CPU module is powered by an external 24 VDC source. This source isnormally supplied by one of the Continuum Power Supply Modules, however you can

attach a third-party supply to the NetController if you follow the information provided in

the next few pages. The input power connector is located on the left side of the CPU

module case and consists of five pins.

The power input connector is a five-pin male assembly that is designed to easilyinsert directly into the right side (output) connector of any Continuum Power Supplymodule. The signals within that connector are as follows:

PIN Function5 +24 VDC

4 24 VDC Return

3 Ground

2 Low Battery Signal*

1 AC Power Present Signal*

* Only supplied from Continuum UPS version Power Supplies

It is assumed that the CPU is directly connected to a power supply module as shownbelow:

Power Supply CPU

8 TAC


17/76

The power supply generates a +24 VDC source for the CPU and all othermodules in the system. This power source is located on pins 4 and 5.Pin 3 (Ground) is intended as an Earth ground connection.

The NetController consumes a maximum of 10 Watts of 24VDC power.

The Continuum UPS version power supplies provide the CPU with two power statussignals on pins 1 and 2. Their function is as follows:

AC Power is a logic signal that is intended to communicate that AC power isavailable. When AC is interrupted and the power supply has switched to UPSbattery mode, this signal presents a logic low. The CPU can use this signal tostart an orderly system shutdown. For more information on the use of this signal,refer to the section titled UPS Programming .

Low Battery is a logic signal that is intended to communicate that the voltage ofthe battery has dropped below 22 Volts. When the power supply has switched toUPS battery mode, this signal presents a logic high. Should the battery voltagedrop, this signal switches to a logic low. The CPU can use this signal to start an

orderly system shutdown. For more information on the use of this signal refer tothe section titled UPS Programming .

WarningMake sure that AC power is not applied (switch is off) to the power

supply while you are connecting the CPU module. The module could be

damaged or you could receive an electrical shock that is life threatening.

ESD WarningTo avoid damaging electronic components because of the discharge of

static electricity, always ground yourself before touching any boards or

other internal components of Andover Continuum devices.

• At the very least, discharge yourself by touching metal first.

• If possible, use a grounding strap or heel plate.



18/76

Third-Party DC Power Connection

In situations where a large number of I/O modules are used, the power available fromthe standard Continuum power supply module may not be sufficient. In thesescenarios you can either use an auxiliary power supply for the extended I/O group oryou can replace the main power supply with one that can handle the entire job.

When using a third-party power source to supply a Continuum system it is necessarythat you connect the power as shown below. Normally all power flows from thesupply and through the NetController. Third party supplies should connect directly tothe I/O module power bus. That way the internal current limitations of theNetController do not detract from your system design.

Earth Ground Connection

To insure reliable operation under all adverse conditions, the CPU module must

have a wire connected to it and Earth ground. The wire should be as short as

possible, ideally 6” or less, and the wire gauge should be a minimum of 18 AWG. Pin

20/76

Output Power-I/O Connections

The Continuum NetController CPU module includes a connector on the upper rightside of its case for further distribution of the 24 VDC input power and special I/Ocommunications signals to all I/O modules. Continuum I/O modules use these signals

for power and communications.

The power-I/O connector is a five pin male assembly that is designed to easily insertdirectly into the left side connector of any I/O module. The signals within thisconnector is as follows:

54321

PIN Function

5 +24 VDC

4 24 VDC Return

3 Shield

2 Comm B

1 Comm A

The main system power supply generates a +24 VDC source for the CPU. Thispower source is received through the input power connector on the left side of theCPU module and sent through to pins 4 and 5 of this connector.

All the Continuum I/O modules can operate at 24V. Some have extended ranges to allowoperation at lower voltages. Refer to the individual specifications for each module.

Communications between the CPU and I/O modules is through a two-signal serialinterface that is factory configured as either RS 485 ACC-LON or FTT-10A.

Pins 1 and 2 (Comm A and Comm B) provide the electrical connection for this interface.Pin 3 (Shield) is the communications signal shield connection. This is not an Earthground connection. Proper shielding requires that the installer connect all shieldstogether. The CPU (if grounded properly) provides the single Earth ground point for

all modules. Each I/O also has its own Earth ground connection.

21/76

Connection of I/O Modules

The CPU can directly connect to I/O without the use of cables through a system of built-inplugs and jacks. All I/O modules include two complementary module inter-connectors.

Creating a system is as simple as physically plugging the modules together.

22/76

Maximum Number of I/O Modules

The Continuum system allows for a maximum of 32 I/O modules per CPU. There is alsoa limit based upon the capacity of the power supply feeding the modules.

Note: It is possible to insert auxiliary power supplies into the I/O bus to increase thenumber of modules supported up to the maximum of 32. The Power Supply Reference,30-3001-702, includes information on auxiliary supply installation.

• PS 120/240 AC 50 U, UPS power supply: 35 Watts of power available



• PS 120/240 AC 50, non-UPS power supply: 50 Watts of power available



• PS –48 DC 50, Battery operated power supply: 50 Watts of power available

• PS –48 DC 50 U, UPS Battery operated supply: 50 Watts of power available

UPS power supplies (except the –48 DC 50 U) include battery charging circuitry that

consume 15 Watts of the total power available. This is why the UPS supplies are listedwith less available Wattage.

To determine the maximum number of I/O modules each power supply can support, subtractthe power requirements for each module from the maximum available per supply.

If the supply also powers the NetController CPU be sure to subtract the 10 Watts itconsumes.

The power requirements for the NetController and each I/O module* is listed below:

Maximum Length of I/O Bus

The I/O Bus is a network. Networks are limited by cable lengths because electricalsignals lose power and distort as they travel along wire. The longer the wire, the lowerthe signal strength. The following are the maximum cable length specifications:

RS-485 2000 ft. (610 m)

FTT-10A 8858 ft. (2700 m) double termination

1640 ft. (500 m) free topology

Cable Recommendations

Data Cable (Pins 1, 2 and 3)You must use shielded cable for the data lines (pins 1, 2 and 3) to provide reliablecommunications and to ensure compliance with the Class A FCC limits (USA).

ACC-LON (RS-485)The data cable should be 24-gauge (0.25 mm), single-twisted-pair, tinned, shielded

copper wire with an impedance of 100-120 Ohms and a nominal velocity ofpropagation of 78%.

Capacitance of the cable should be below 12.5 pF/ft (41 pF/m) between conductorsand below 22 pF/ft (72 pF/m) between the conductor connected to ground and thenext conductor.

The following cable meets all of the data cable specifications:

Belden 9729, double twisted pair, shielded

ACC LON FTT-10A

The installer may choose a variety of cables, depending on cost, availability, andperformance. Performance may vary with cable type. The transmission specificationdepends on such factors as resistance, mutual capacitance, and the velocity ofpropagation. System performance on the cable types is shown below. They arelisted in order of performance.

24/76

16 TAC

Power Cable (Pins 4 and 5)

You should use shielded cable for the power lines as well (pins 4 and 5) to ensure noiseimmunity and therefore more reliable operation. The shield would be connected to pin 3like that of the data cable.

The gauge of the power cable is determined by the power it carries. As indicatedpreviously, the longer the wire the more voltage drop. Do not allow the power supplyvoltage measured at the furthest remote module to drop more than the allowable amount:

24 VDC modules: 2V (1V for the power run and 1V for the return run)10-28 VDC modules: 12V (6V for the power run and 6V for the return run)

Voltage drop can be calculated by using Ohms Law:

Voltage=Current x Resistance

A table providing some guidelines for choosing wire gauge is included on the next page.

Connecting Remote I/O Modules with ACC-LON (RS-485)

The Continuum system allows I/O modules to be placed in a remote location from theCPU (NetController). Long cable lengths in ACC-LON (RS 485)-based networks cancause signal communications problems on the I/O bus.

When locating an I/O module remotely on an RS 485-based bus, it is necessary to add

an external 120Ω

terminator resistor to the bus to compensate for the distance. Theterminator must be connected at both ends of the bus for proper operation.

The following diagrams are typical installations that indicate the correct placement of theterminator:

The I/O Bus that needs to be terminated is the one formed by the cable attaching theremote module to the CPU. In this case, a terminator resistor is connected across the

Connecting Remote I/O Modules with FTT-10A

The ACC LON bus topology wiring (RS-485) consists of a network of I/O modules thatare interconnected using a shielded twisted wire pair. In accordance with RS-485guidelines, all of the devices must be wired in a bus topology to limit electrical reflectionsand ensure reliable communications. There is a high cost associated with installing and

maintaining the cable plant that links together the many elements of an RS-485 basedcontrol system. Bus topology wiring is more time consuming and expensive to installbecause the installer is unable to branch or star the wiring where convenient: all devicesmust be connected directly to the main bus.

The best solution for reducing installation and maintenance costs and simplifying systemmodifications is a flexible topology communication system. Echelon Corporation’s freetopology transceiver (FTT) technology offers just such a solution, and provides anelegant and inexpensive method of interconnecting the different elements of a distributedcontrol system.

The FTT-10A free topology architecture allows you to wire Continuum I/O modules withvirtually no topology restrictions.

Unlike ACC-LON, the FTT-10A system uses a free topology wiring scheme that supportsstar, loop, and/or bus wiring. This design has many advantages. First, the installer is freeto select the method of wiring that best suits the installation, reducing the need foradvanced planning and allowing last minute changes at the installation site. Second,retrofit installations with existing wiring plants can be accommodated with minimal, if any,rewiring. This capability ensures that FTT-10A technology can be adapted to both old andnew projects. Finally, free topology permits Continuum systems to be expanded in thefuture by simply tapping into the existing wiring where it is most convenient to do so. This

reduces the time and expense of system expansion, and from the customer'sperspective, keeps down the life cycle cost of the free topology network.

IMPORTANT FTT-10A NETWORK INSTALLATION NOTICEThe termination and wiring information provided in this guide is a small subset of thecomplete technical information presented by Echelon Corporation in their FTT-10A

installation documentation. It is highly recommended that you obtain their document andread the sections pertaining to network installation. As a courtesy, the Echelon FTT-10A

FTT-10A Cable Termination (see important notice on the previous page)When locating an I/O module remotely on a LON FTT-10A-based system, it is necessaryto add an external terminator to the wiring to compensate for the distance. The terminatorcan be connected at both ends or at one central point.

The following characteristics apply when using doubly terminated or free topology wiringschemes:

1. Network lengths vary for doubly terminated vs. free topology.

2. Network lengths vary based on cable type.

3. FTT-I/O has two specifications for a free topology network: total wirelength and node-to-node wire length (which also applies to termination).

A doubly terminated bus may have stubs of up to 3 meters from a bus to each node.

Communications Ports

The Continuum NetController module includes connections for communications withexternal devices such as printers, Infinet controllers and others. These connectionsare called Comm Ports. It also optionally includes network connections.

The NetController includes four Comm Ports called COMM1 through COMM4 withthe following possible configurations:

COMM1 – RS-232 / RS-485 Infinet , Autoset, Command, L-bus, Xdriver,TankNet or Printer (RS-232), Not Configured

COMM2 – RS-485 Autoset, Command, Printer, Infinet, Xdriver orTankNet, Not Configured

RS-232 Connections

A standard 8-pin shielded insulation displacement RJ-45 termination connector isprovided for the RS-232 interconnection. Protective ground is connected to the outershield of the connector that is connected to the shield of the cable. Both COMM 1and COMM 3 provide the same connector.

COMM 3 can be configured as an internal modem or an RS-232 connection. Whenthe internal modem option is installed, the RS-232 connection is no longer available.

The RS-232 pin connections are shown below:

Connection to a standard RS-232 device using a cable terminated with an RJ-45 and 25-pin or 9-pin D-type connector is shown below:

Use a cable of this type to connect to printers and other devices. Depending on thedevice, it may be necessary to reverse some or all of the connections. In mostcases, this is easily accomplished using an adapter called a “null modem.”

RS-232 COMM Port Configuration

After physical connection, the COMM Port must be configured as an RS-232 deviceproperly through the Command Terminal interface or the Continuum workstation.

Configuration requires selecting the type of device to be connected (i.e., Printer,Command, etc.) and setting various communications-related parameters. Refer to theCommand Terminal User Guide, the Continuum CyberStation Configurator’s Guide or the Continuum online help system for detailed information regarding configurationissues.

L-bus Port Configuration

COMM 1 can support L-bus devices only when used with an RS-232 to RS-422 levelconverter. The LA-1 converter may be used for this purpose.

For installation and configuration information refer to the LA-1 Installation Guide, 30-

3001-813.

Note: L-bus and TankNet are mu tual ly exclusive. When L-bus is c onfigu red on

RS-485

The NetController can be connected to other standalone Andover Continuumcontrollers such as local VAV controllers and touch screen displays. Communicationprotocol and interface to these devices is called the Infinet network. Theseconnections are accomplished using any of the three RS-485 ports.

COMM 1, COMM 2 and COMM 4 include RS-485 connections. A removable screwterminal type connector is provided for the interconnection.

The Infinet is a high-performance, token-passing protocol designed for Infinetcontrollers where more than one controller can be the network master at a time.

Infinet is physically wired using two conductor shielded twisted pair cable thattransmits data at a rate of up to 19.2 Kb/sec. Although Infinet has a token-passingdata access system, it can have a combination of daisy-chained bus and startopology.

Cable lengths of up to 4,000-ft (1,220 m) daisy chained from Infinet controller to

Infinet controller for every 31 Infinet controllers on one arm of a star are supported. After 31 nodes or 4,000 ft (1,220 m), an InfiLink 200 or InfiLink 210 signal repeater isrequired to add more nodes to the network or further extend the cabling. Using anInfiLink 210 allows you to extend the length of Infinet with fiber optic cable,recommended for running cable between buildings and through noisy environments.You can have a maximum of 127 nodes on one Infinet with InfiLink 200 or 210 .

Only two Infinet connections are supported. Therefore, the following Infinet combinations are valid:

COMM 1 & COMM 2

Although COMM 4 is an RS-485 port, it does not support Infinet .

For more detailed information on the Infinet network, consult the Infinet NetworkConfiguration Guide, 30-3001-169.

Ethernet

The NetController can be connected to workstations and other NetControllers via anEthernet interface. These connections are accomplished via one of several physicalmethods. 10BASE-T (RJ-45) and 10BASE-FL (fiber optic) connection options areavailable. Only one of the methods is installed depending upon your configuration.

The Ethernet is a high-speed CSMA/CD local area network (LAN) that includes allTAC network-level controllers and workstations and the network software that makesthem communicate.

Ethernet consists of a minimum of two NetControllers or a NetController and aworkstation. Data transmits over the Ethernet at a rate of 10 Mb/sec. Depending onyour particular installation, you may want to use unshielded twisted-pair (10BASE-T),fiber optic cable (10BASE-FL) or all in a variety of combinations.

Ethernet can be constructed as a bus or daisy chain or in a combination bus/daisychain and star topology called “distributed star” topology.

Andover Continuum’s Ethernet implementation is a baseband network, connected byup to 1,635-ft (500 m) of twisted pair cabling. The number of nodes on the networkdepends on the type of cable you use. For each applicable segment of coaxial cable,you can have 30 nodes. Each segment of twisted pair cable connects two nodes inan arrangement called a “point-to-point” configuration.

As with any baseband network, Ethernet is easy to install. It requires only cabling andinterface modules. Depending on cable length, you may need an electronic repeaterand/or cable switching box, to extend the amount of cabling to its maximum, to form adistributed star topology, and to utilize every type of cable available.

Ethernet NodesThe two types of nodes on the Andover Continuum Ethernet are Network Controllers(e.g., NetControllers) and workstations. Each controller requires two types of IDs: oneyou assign strictly for use by the local network, called the EnergyNet ID, and anotherthat allows the unit to be used on not only your Ethernet, but on a world-wide Internet(called the IP Address).

Configuration of both these identifiers is done through the Command Terminalinterface or through the Continuum workstation and locally at the controller throughthe use of an externally connected terminal attached to COMM Port 3.

A complete procedure for setting up the Ethernet addresses in the NetController canbe found in the Commissioning section of this document.

Ethernet Connections

The controller module is equipped with an on-board Ethernet interface—completewith connector(s)—corresponding to one of the following Ethernet media types:

10BASE-T

10BASE-FL

Different connectors, cable limitations, and network termination requirements apply tothe Ethernet, depending on which type of option your NetController uses.

10BASE-T Ethernet

Cable Limitations:

This option provides a standard RJ-45 connector for Ethernet. Unshielded twistedpair cable is used to form this type of network (you actually use a cable with dualtwisted pairs—one for the transmit signal, and one for the receive signal). Themaximum cable length you can use between two nodes is 327 feet (100 meters). Themaximum length for the network segment is 1,635 feet (500 meters). If you need touse a cable that exceeds the recommended maximum length, use a networkrepeater.

10BASE-T Cable Specifications

Cables used to form the 10BASE-T Ethernet should be twisted pair wire, (Category 3(CAT-3) or Category (CAT-5) with CAT-5 preferred). The cable should have anominal impedance of 100 Ω (85 –111 Ω).

Token Ring

The NetController can be connected to workstations and other NetControllers via astandard Token Ring interface. This connection is accomplished via one RJ45 jack.

Token ring connects workstations and controllers together in a closed ring. Deviceson the ring cannot transmit data until permission is received from the network in theform of an electronic 'token'.

The NetController connects to the Multistation Access Unit (MAU or MSAU) throughan RJ45 terminated lobe cable consisting of four wires; two for transmit and two forreceive. The cable can be Shielded Twisted Pair or Unshielded Twisted Pair. Although the token ring stations are attached to the MAU in a physical starconfiguration, a true ring is maintained inside the MAU.

The NetController Token Ring RJ-45 connector is an eight conductor unit of whichfour pins are used:

Pin 3 - Transmit -

Pin 4 - Receive +Pin 5 - Receive -Pin 6 - Transmit +

Distance Between Controllers, Workstations and Other Nodes

In token ring networking, distance requirements differ from vendor to vendor. In

general terms, the recommended standard distance between stations for two-pair

shielded cable is approximately 300 meters, and the recommended standard

distance between stations for unshielded cabling is about 150 meters.

Token ring distances are computed as the distance between repeaters. In a tokenring network, each workstation with a Network Interface Card (NIC) and eachNetController is a repeater. Therefore, the length between stations cannot exceed thecable lengths listed above.

Some manufacturers use 'active' MAUs that can regenerate the token ring signal andact as a repeater. In these cases, the distances between the token ring workstationsand the MAUs can be much larger than many 'passive' MAUs. Many active MAUshave other network management features such as SNMP capabilities and auto-station removal for stations inserting at the incorrect speeds.


47/76

Token Ring Speed Selection

The NetController supports Token ring speeds of 4 megabits per second (500,000 bytesper second) and 16 megabits per second (2,000,000 bytes per second). Selection isdone via a small switch located inside the NetController case.

The power status indicator is ON if the NetController module is receiving power from

the power supply.

CPU

The CPU (for Central Processing Unit ) indicator flashes constantly (may appear as

if it is steady on) if the NetController module is active—many refer to this indicator as

the NetController’s “heartbeat.”

SCAN

The scan indicator flashes once for every scan executed by NetController.

ERRORThe ERROR indicator remains OFF until an error occurs.

If the NetController fails an internal system test, the ERROR indicator blinks a preset

number of times, then pauses, and repeats the blinking and pausing sequence—this

blinking pattern will persist until you reset the controller. The number of blinks

between pauses identifies the specific problem (as shown in the table below).

ERROR Ind icator B link Rates (before a paus e)

# Blinks Type of Failure

17 CX Firmware is corrupt (Bad Flash/ROM or bad update)

18 LAN Card's memory is faulty - Try replacing the LAN Card.

19 Problem creating certain System Tasks - Maybe due to lack of memory.

20 Problem with the NIC - Try replacing the LAN Card

21 reserved

22 RTC Failed - Possible Hardware issue

23 reserved

24 Problem with the PIT chip - H/W related

25 Problem creating Timer Tasks - Maybe due to lack of memory

26 to 27 reserved

28 The RAM memory is faulty or bad. Try replacing the RAM module(s).

29 to 62 Problem creating certain System Tasks - Maybe due to lack of memory.

63 Copy protection - Flash Upgrade file is invalid for this Controller (UPD file is Serial #protected)

64 Problem creating the Uprev task - Maybe due to lack of memory.

Note: If a Plain English program disables due to an error, the ERROR indicator illuminates and staysON (without blinking)—if this occurs, you can turn the indicator off by setting the ERRORS systemvariable to zero.

Operation

Power OnIMPORTANT

Before applying power to the NetController make sure all connections are secure.

The NetController has no power switch. It is assumed that it is connected to anappropriate Continuum power supply module. To apply power to the system, the powerswitch located on the left side of the power supply module case must be depressed.

The switch is a rocker type with each side marked according to function. Pressing the sidemarked with the I turns the power on. The POWER status indicator illuminates.

To remove power, press the side marked O.

Once power is applied, any pre-loaded Plain English programs residing in theNetController begin operating. Otherwise, the power-on system tests run and thecontroller awaits instructions.

Commissioning

Once the NetController has been mechanically installed and electrically connected, thecontroller’s network address information must be entered so the Continuum software cancommunicate with the controller. This operation is called “commissioning”.

What You’ll NeedCommissioning a NetController requires a laptop or other computer that is running an ASCII terminal emulator. Terminal emulators are common programs that allow you tocommunicate simply with RS-232 devices. One emulator program, HyperTerminal, is builtinto Windows and is available from the Accessories menu off of the Start menu.

ConnectionsYou can connect to the NetController either directly or through a modem, using a devicewith a keyboard and display. These devices are often referred to as ASCII terminals, TTYreplacements, or terminals. We call them command terminals.

Your command terminal must be DEC VT100 or VT220 compatible, or your computermust be running a terminal emulation program for one of these terminals.

Communications between the NetController and the command terminal is through theRS-232 interface. Connect the NetController Comm Port and the command terminal’sSerial or Comm port.

Connections made through a modem are straightforward; however, refer to the modemmanufacturer’s guidelines before making the connection.

Direct connection requires an RS-232 Null Modem cable. The NetController’s defaultstate is for connection to the CyberStation via a modem. If you are connecting directly tothe controller via a network, select “MODEM RS-232 OVERRIDE” on the NetController’sdisplay panel.

RS-232 communications operates at a number of speeds called the Baud Rate. Both theNetController and the command terminal must be set to the same baud rate tocommunicate. Use Comm3 on the NetController. The following table shows the correctsettings:

RS-232 Settings

Baud rate 9600

Data Length 8 bits

Parity None

Stop bits One

UPS Programming

The NetController acts as the intelligence in your system. Plain English programs arecreated and then downloaded from the Command Terminal or from the Continuum workstation and are executed by the CPU within this module. There are several PlainEnglish commands that, when inserted into your programs, allow the NetController tosense when the system is operating on battery backup power (UPS operation) and toremove power from critical areas before the available power is depleted.

The following Plain English keywords and system variables pertain to this UPS operation:

• PowerFail

• CPUPower

• ModemPower

• PowerUpTime

Detecting a Power FailureWhen the main AC power fails, the UPS versions of the Continuum power supply signalthe NetController that they have lost AC power. You can add a routine to your program totest for this occurrence using the PowerFail system variable:

If PowerFail is ON then …..

Turning Off Various SubsystemsWhen a loss of power is detected, it signals that the system is operating using backupbatteries. In order to conserve power during this operation, you have the ability to remove

power from the optional modem and or the CPU itself. The following commands would beused in both of these scenarios:

If PowerFail is ON then SET ModemPower to OFF ‘ turns off power to the modem

If PowerFail is ON then SET CPUPower to OFF ‘ turns off power to the CPU and allsubsystems including the modem

How Long Was I Down?The PowerUpTime system variable can be used to keep track of how long it has been

since the last power failure.

Command Terminal Interface

What is the Command Terminal Interface?

Continuum NetControllers include a firmware-based user interface through whichcommands may be passed to configure and control its actions. This interface requires aseparate personal computer running a terminal emulator program or a dedicated ASCIIterminal. Communications with the Command Terminal firmware are carried out over an

RS232 link through any CX Comm port configured as AutoSet.

The typical and recommended path for programming a NetController is through the useof a separate personal computer (Continuum workstation running the CyberStationapplication). However, if a CyberStation is not present, it is possible to program theNetController directly through the Command Terminal interface. The Command Terminalinterface has the same capabilities of a Continuum CyberStation except for the followingitems:

• Configuring Alarms

• Schedules

• Area Objects

• Personnel Objects

Particularly valuable as a site troubleshooting aid, using the Command Terminal interfacemakes it possible to write programs, create and access system points and configurationof networks and SNMP alarms.

The Command Terminal Configuration Guide, 30-3001-843, provides you with detailedinformation about using the Command Terminal mode, including procedures to:

• Commission the NetController

• Create and configure object types

• Create and configure points

• Save and reload controllers

• Use the program editors to create controller-resident Plain English programs
