BACnet Integration Guide Rev. 9/28/2011 1 2011 Automated Logic Corporation

You can integrate BACnet devices into a WebCTRL system using one of the ALC controllers

listed below that provide third-party points*. The ALC controller serves as a master device.

ALCControllers LGR25

LGR250

LGR-1000

ME-LGR25

ME-LGR200

ME812u-LGR (200 points)

Read/write capability Can read from and write to the third-party equipment

Third partySupported equipment Any device that supports the BACnet protocol

Supported media IP, Ethernet, ARC156, MS/TP (9600, 19200, 38400,

or 76800 kbps), and PTP

* The point allowance of a controller (the number after the letter R) applies only to that controller.

For example, if you purchase an LGR-1000 that provides 1000 third-party points and you

download control programs that use 500 third-party Network I/O points, you cannot apply the

unused 500 points to a different controller.

If you have legacy ALC controllers that use point packs, seeAppendix D(page23).

You need the following items, information, and skills for the integration process:

The system's SiteBuilder database

The ALC controller's Technical Instructions

The third-party device's:

BACnet network number and MAC address or the Device instance Points list including BACnet Object ID's (object type plus object instance)If the third party device is not installed or commissioned yet, ask the third-party

vendor for this information. Then useAppendix A(page18)to write correct BACnet

address strings in your microblocks.

The baud rate of the third-party device if running MS/TP

Verification that all communication settings have been set on the third-party device

Experience creating control programs with EIKON LogicBuilder

Experience installing, wiring, setting up, and downloading to the ALC controller

Overview

Before-you-begin checklist

Follow the steps in this document to integrate one or more third-party BACnet devices into

a WebCTRL system using an ALC controller. To install and network the ALC controller, see

the controllers Technical Instructions.

WebCTRLs BACnet Discovery locates all accessible BACnet networks, BACnet devices,

and BACnet objects (including devices in your WebCTRL system) on a BACnet network.

To use BACnet Discovery:

1 On the WebCTRL CFGtree, selectSystem Settings.2 On the Communicationstab, clear the Use Static BACnet Bindingscheckbox so that

bindings are dynamic.

NOTE Always run your system with dynamic bindings (clear the Use Static BACnetBindings checkbox) unless you are: Troubleshooting BBMD's. See "Setting up BBMD's" in WebCTRL Help. Using NAT routing. See "To build a Network tree" in SiteBuilder Help.

3 On WebCTRL's CFGtree, selectConnections.4 On the Configuretab, stop the BACnet/IP connection.5 While the connection is stopped, enter or verify the server's IP Addressand Subnet

Maskfor the BACnet/IP connection.6

Restart the connection.7 On the NETtree, select the system level.8 Click Devices.9 On the BACnet Discovery tab, click Go to discover BACnet sites for the system. An

item called Discovered Networksappears in the tree. After all sites are found, closethe status dialog box.

10 To discover BACnet networks, select Discovered Networks, then click Go. A list of allBACnet networks appears in the NET tree. After all networks are found, close thestatus dialog box.

TIP Run a commstat manual command to determine which device routes to eachnetwork. The BACnet Bind Show Network section of the Commstat window shows theIP address of the router to each network.

11 To discover BACnet devices on a network, select a network on the NET tree, then clickGo. After all devices are found, close the status dialog box. Click the plus sign besidean item to expand the list of devices.

The integration process

1 Discover BACnet networks devices and objects


5/27


12 To discover BACnet objects on a device, select the device in the NET tree, then clickGo. After all objects are found, close the status dialog box. A list of all BACnet objectsin this device appears on the NET tree.TIP Make sure you are discovering objects in the correct device. It may take sometime to discover objects in devices with more than 100 objects.

13 On the NET tree, select a discovered network with devices or a single device.14 Click the Export button to export the BACnet information.15 Name and save the .discovery file in any folder.

NOTES Some third-party BACnet devices may not be discovered because they do not support

the BACnet methods required for auto discovery.

If the discovery process returns ambiguous information, such as multiple points withsimilar names, contact the third-party manufacturer's representative for clarification.

Device configuration or network load can prevent WebCTRL from showing all BACnetdevices. If you do not see a BACnet device that you expect to see, check the system's

BBMD configurations. If the configurations are correct, try the discovery process

again.

If a third-party device is not discoverable, you must get the device's address and pointlist information from the third-party vendor. Then useAppendix A(page18)to write

correct BACnet address strings for your microblocks.

Use Network I/O microblocks and Display microblocks to read from or write to BACnetobjects in a third-party BACnet device.

Use Network I/O microblocks if any of the following is true:

An ALC control program must read from or write to third-party BACnet points forautomatic control.

You want to trend values from a third-party device that does not support BACnettrends.

You want to display third-party values that require unit conversion or other mathprocessing.

NOTES Each Network I/O microblock that is addressed to a third-party object property counts

against the point limit of an ALC controller.

Display microblocks do not count against the point limits of ALC controllers. Both Network I/O and Display microblocks count against the 500-point limitation of

WebCTRL 500.

Display microblocks cannot use logic, including the logic that a thermographicfloorplan requires.

Use one of the following methods to define how every Network Input or Total Analog

microblock reads the object property referenced in the microblock's Address field.

How it works The Network Input or Total Analog microblock subscribes with the targetBACnet object. An analog target notifies the microblock if the target's

value changes by more than the target's BACnet COV_Increment. A

binary target notifies the microblock when it changes state. See

Appendix E - COV subscription details(page24).

Benefits Can decrease network traffic by preventing unnecessary updates ifthe target's COV_Increment is set appropriately. See step 2 in "To

set up" below.

Drawbacks Can generate excessive network traffic if the target'sCOV_Increment property is too small. See step 2 in "To set up"

below.

Can delay detection of a dead device or of network problems . SeeTo speed detection of a dead device(page10).

To set up 1 Set the microblock's Refresh Timeto 31 seconds or more.2 If the microblock's Address field references an analog property, set

the target's COV_Increment property to the smallest amount by

which the value must change for the target to notify its subscribers.

The optimal COV_Increment is large enough to prevent unnecessary

updates but small enough to be useful to the control program(s)

receiving the updates.

NOTE If COV subscription fails, the microblock reads the value at the Refresh Timeinterval using the BACnet ReadProperty or ReadPropertyMultiple service. See Method 2:

Polling(page9).

How it works The Network Input or Total Analog microblock reads the target propertyat the Refresh Timeinterval using the BACnet ReadProperty orReadPropertyMultiple service

Benefits Allows rapid detection of a dead device or of network problems Does not require additional memory

Drawbacks Generates unnecessary network traffic if a value does not changefrequently

Misses value changes that occur between pollings Can overwhelm the target's controller if many microblocks request

the same property value (such as outside air temperature). The

BACnet object must send the value to each microblock that polls for

that data.

5 Configure Network Input and Total Analog microblocks

Method 1:

BACnet COV

subscriptions

Method 2:

Polling


12/27


To set up Set the microblock's Refresh Timeto 30 seconds or less.NOTE The ALC microblock will not poll at a Refresh Timeinterval lessthan 1 second.

BACnet ReadProperty and ReadPropertyMultiple servicesSee the BACnet specification for details on these services.

ReadPropertyMultiple occurs if:

two or more microblocks in a controller read more than one target in the sameremote controller,

the Refresh Timein two or more microblocks expires at the same time, and the remote controller supports the service.

If a BACnet object's device loses network communication, a network input reading the

object's value does not detect the failure until

the network input's next subscription (up to 10 minutes) if using BACnet COVsubscription, or

the Refresh Time expires, if pollingYou can use a small Refresh Timeto poll more often, but this can generate unnecessarynetwork traffic under normal conditions.

To use the benefits of BACnet COV subscription, but overcome the potential delay in

detection of a dead device, send a constantly changing value from the BACnet object's

control program to a network input using BACnet COV subscription. If the value stops

changing, the network input's control program generates an alarm.

EXAMPLEThe logic in the BACnet object's control program that sends the value. The BACnet Analog

Value microblock has a COV Increment of 0.5.

The BACnet standard allows multiple formats for creating a valid address in each

microblock that you use to read from or write to a third-party BACnet point. Some are

shown below.

CAUTION When integrating third-party devices into your system, most communicationproblems are caused by incorrect data or typing errors in the microblock's Address field.

NOTE Numeric values in a BACnet address can be entered using decimal or hexadecimalnotation. Type0x before a hexadecimal value.

Device- Use one of the following: EXAMPLESDevice instance number bacnet://2010/

BACnet device name bacnet://MyDevice/

Network number: MAC address

(of third-party device)

bacnet://1234:35/bacnet://1234:0x23/

The word "this" if a network point

requests a value from another controlprogram in the same ALC controller.

Avoids network traffic. Requires v2.05 or

later controller driver.

bacnet://this/

A single * (wildcard) that sends out a

request on the network for all devices

that contain the Object specified in the

address. (See Object below.) Themicroblock subscribes to the nearest

responder.

NOTES

You can use an * in the address ofNetwork Input and Total Analog

microblocks.

An address with an * is restricted tothe present_value property (the

default when you do not specify a

property).

Requires a v3.04 or later driver.

Object- Use one of the following: EXAMPLESObject type: Instance number

(See NOTES below)

BACnet object name

bacnet:///ai:2

bacnet:///MyObject

NOTES For object type, you may type the abbreviation (not case sensitive), the full

name, or the object type number. Some standard BACnet object type numbers

are listed below. See the BACnet standard for a complete list. For proprietary

BACnet objects, see the object's manufacturer.

You can reuse a control program for multiple pieces of identical third-party equipment.

To reuse a control program for identical pieces of equipment:

1 In EIKON LogicBuilder, open the control program you want to reuse.

2 Add a Device Alias microblock.

3 In the Property Editor, type a meaningful character string such as the model numberor name of the third-party device in the Device Alias field.

4 Select Control Program> Edit Common Properties > Display Pointstab.5 Select the All radio button.6 Replace the numbers in the Device Aliascolumn with the model number or name of

the third-party device exactly as you typed it in step 3.

7 In SiteBuilder, assign this reusable control program to each instance of the third-party

device.

8 In your running system, for each instance of the third-party equipment, change the

Device Alias microblock's Device Instancenumber to match each specific device.

For WebCTRL to retrieve third-party data into a display microblock that must pass through

one or more NAT routers, you must create a model of the third-party network on

SiteBuilders Networktree.1 In SiteBuilder, add the third-party equipment to the Geographic tree.2 In the Equipment Propertiesdialog box, select the control program you created in

EIKON LogicBuilder.

3 On the SiteBuilder Network tree, add (model) the third-party device.NOTES If the third-party device is on a different BACnet network than your ALC

equipment, you must also add the third-party network.

If the third-party device is under a third-party router, you must add the third-partyrouter and its network before adding the third-party device.

TIP For a third-party device on a different BACnet/IP network than any ALCdevices, use BBMD's to communicate across an IP router. See the ALC website

(http://accounts.automatedlogic.com)for more information on BBMD's.

4 On the SiteBuilder Network tree, in each third-party devices Device Propertiesdialogbox, General tab: Type the Address and Device Instanceinformation from the third-party vendor. In the Device Definitionfield, select Third Party Deviceor Third Party DeviceRouter.

NOTE To use NAT routing, you must select the Use Static BACnet Bindingsfield onWebCTRL's System Settings> Communicationstab.

The following controllers use point packs (100 points per pack):

LGE LGRM-E S line M line UNI WebPRTLNOTES The LGE, LGRM-E, and WebPRTL can communicate on any BACnet network type (IP,

Ethernet, ARCNET, MS/TP, or PTP). See the router's Technical Instructionsfor details.

S line, M line, and UNI controllers can communicate using BACnet on ARC156 orMS/TP networks. They can reference a third-party BACnet point on any network type if

a BACnet route to the point exists.

A controller that provides third-party points does not use point packs. A system can use both controllers that provide third-party points and controllers that

use point packs.

EXAMPLESFor third-party BACnetintegration in a systemwith this hardware...

When an input (Network Input or Total Analog microblock) subscribes with a BACnet target

(object property), the input sets a 21-minute subscription Lifetime in the target. The target

responds with a COV notification that includes the target's value and time remaining from

the original subscription Lifetime (TimeRemaining). The input resubscribes with the target

every 10 minutes to keep the target's BACnet subscription service active. The NextSubscriptionfield on the input's Propertiespage shows the time remaining until theinput's next subscription.

The target also sends a COV notification that includes the target's value and subscription

Lifetime TimeRemaining when the target's value changes by more than the target's

COV_Increment.

If the ALC target has one subscriber, the target sends COV notifications directly to that

subscriber. If the ALC target has more than one subscriber, it broadcasts its COV

notifications to optimize network traffic. A third-party subscriber can participate in this

broadcast scheme by subscribing for Unconfirmed COV notifications with a Process ID of

0. Otherwise, the ALC target maintains and responds to the third-party subscription

separately with its own Lifetime timer.

The ALC input compares the TimeRemaining value in each COV notification broadcast the

target sends to its (Next Subscription time + 11) to determine whether another input has

subscribed since it did. If another input has subscribed more recently, the input adds 10

minutes to its Next Subscriptiontime. This allows the COV Subscription request from thelast subscribing input to keep the subscription service active for all subscribers to the

same data.

Input 2 keeps the subscription service active at the target with a minimum of networktraffic.

NOTE If an input receives COV notification with a target TimeRemaining < 11, which couldhappen if the last subscribing input loses communication with the target, the input

resubscribes immediately.

COV notification rate

COV notifications from a BACnet object property are controlled by that property's BACnet

COV_Increment. When the absolute value of the difference between the property's

Present_Value and the value sent in the last COV notification is greater than the

COV_Increment, the object broadcasts a COV notification. For ALC controllers, the rate of

notifications is further limited by two internal processes.

1 The control program's execution rate determines how often the check against

COV_Increment is performed.

2 The controller's pending COV Notification task has built-in delays to prevent COV

notifications from consuming the controller's CPU processing time.

The built-in delays are as follows:

If more than 15 COV notifications are pending delivery, the controller inserts a 50

millisecond delay after each set of 15 notifications. Once the entire list of pending

notifications is serviced, the controller inserts another 50 millisecond delay. This

results in a maximum COV notification rate of 300 COV notifications per second per

ALC controller.
