1 Connect the third-party device to the Automated Logic®
controller
An Automated Logic® controller can reference a third-party BACnet point on any network type if a
BACnet route to the point exists.
NOTE Communication may be affected by the network bandwidth as well as the frequency and
number of points communicating.
To connect to a BACnet IP device
To integrate a third-party BACnet IP device, or any device it routes to, as shown in Scenario 1:
•
An IP route to the point must exist.
•
You must either have an Automated Logic® IP device on the same IP subnet as the third-party
device, or you must have BBMD's configured to communicate to the IP subnet where the third-party
device lives. See Appendix F (page 27).

6 Configure Network Input and Total Analog microblocks
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.
Method 1: BACnet COV subscriptions
How it works
The Network Input or Total Analog microblock subscribes with the target BACnet
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 (page 25).
Benefits
•
Can decrease network traffic by preventing unnecessary updates if the target's
COV_Increment is set appropriately. See step 2 in "To set up" below.
Drawbacks
•
Can generate excessive network traffic if the target's COV_Increment property is
too small. See step 2 in "To set up" below.
•
Can delay detection of a dead device or of network problems . See To speed
detection of a dead device (page 12).
1
2
Set the microblock's Refresh Time to 31 seconds or more.
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.
To set up
NOTE If COV subscription fails, the microblock reads the value at the Refresh Time interval using the
BACnet ReadProperty or ReadPropertyMultiple service. See Method 2: Polling (page 12).
BACnet Integration Guide
Rev. 10/9/2015
ALC Proprietary and Confidential
11
© 2015 Automated Logic Corporation
All rights reserved
Method 2: Polling
How it works
The Network Input or Total Analog microblock reads the target property at the
Refresh Time interval using the BACnet ReadProperty or ReadPropertyMultiple
service
Benefits
•
Allows rapid detection of a dead device or of network problems
•
Does not require additional memory
•
Generates unnecessary network traffic if a value does not change frequently
•
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.
Drawbacks
To set up
Set the microblock's Refresh Time to 30 seconds or less.
NOTE The Automated Logic® microblock will not poll at a Refresh Time interval less
than 1 second.
BACnet ReadProperty and ReadPropertyMultiple services
See 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 same remote controller,
the Refresh Time in two or more microblocks expires at the same time, and
the remote controller supports the service.
To speed detection of a dead device
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 COV subscription, or
• the Refresh Time expires, if polling
You can use a small Refresh Time to poll more often, but this can generate unnecessary network 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.

EXAMPLE
The 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 logic in the network input's control program that receives the changing value. The SIGNAL analog
network input's Address field contains the address of the BACnet Analog Value microblock sending the
changing signal, and the network input's Refresh Time is 31 seconds.
7 Download the BACnet driver

Appendix A - BACnet addresses
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 communication problems
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 hexadecimal notation.
Type 0x before a hexadecimal value.
Device - Use one of the following:
EXAMPLES
Device 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 bacnet://this/…
another control program in the same Automated Logic®
controller. Avoids network traffic. Requires v2.05 or later
controller driver.
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.) The microblock
subscribes to the nearest responder.
NOTES
•
•
•
bacnet://*/…
You can use an * in the address of Network Input
and Total Analog microblocks.
An address with an * is restricted to the
present_value property (the default when you do not
specify a property).
Requires a v3.04 or later driver.

Appendix E - COV subscription details
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 Next Subscription field on the input's Properties page shows the time
remaining until the input'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 Automated Logic® target has one subscriber, the target sends COV notifications directly to that
subscriber. If the Automated Logic® 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
Automated Logic® target maintains and responds to the third-party subscription separately with its own
Lifetime timer.
The Automated Logic® 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 Subscription time. This allows the COV Subscription request from the last 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 network traffic.
NOTE If an input receives COV notification with a target TimeRemaining < 11, which could happen 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 Automated Logic® 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 Automated Logic® controller.

Appendix F - Setting up BBMD's
To minimize network communications, IP routers do not pass on broadcasts that they receive. If your
system has controllers on different IP subnets separated by an IP router, you must set up a controller
on each IP subnet as a BACnet Broadcast Management Device (BBMD). A BBMD passes BACnet/IP
broadcasts across the IP router to other BBMD's.
IP Router

To set up BBMD's, use the appropriate method in the table below.
If your WebCTRL® system has...
Use this method
50 or less IP subnets with:
Let SiteBuilder automatically
configure your BBMD's.
•
No third-party BACnet routers
•
Authority from your customer to manage all
Automated Logic® and third-party BBMD's on the
network
•
Third-party BACnet routers that support BBMD writes
from the network
Any of the following:
•
•
•
More than 50 IP subnets
Third-party BBMD's that you do not have authority to
manage
Third-party BBMD's that use a non-standard port for
BACnet communications
Set up custom BBMD's through the
WebCTRL® interface or using the
BBMD Configuration Tool.
NOTE If the WebCTRL® server is on an IP subnet without an Automated Logic® BACnet router, register
the server as a foreign device. See "Server on an IP subnet without a BACnet router" in SiteBuilder Help.

To set up BBMDs in SiteBuilder
As you add each Automated Logic® controller to an IP network on the Network tree, check
Automatically Configure My BBMDs on the Address tab. SiteBuilder automatically selects a controller
in each IP subnet as the BBMD and sets up BBMD tables appropriately.
To see which controllers SiteBuilder assigned as BBMD's, select View > Display > BBMD. BBMD's show
B=assigned on the Network tree.
To override SiteBuilder's BBMD selection, right-click a different controller on the same IP subnet, then
select Force to BBMD.
NOTE If you are managing 3rd party BBMD's, you must add every 3rd party device that could be a
BBMD as a 3rd party device router in SiteBuilder.
