Protocol

Defines the protocol used by this Driver. The available items are BACnet MS/TP (RS485) and BACnet IP (UDP), which is automatically selected. Future versions of this Driver must also add the BACnet PTP protocol

Properties

Defines specific properties of this Driver. Those properties are separated into groups General and Device Defaults, described next

Discover device addresses dynamically

Select this option so that this Driver does not use a fixed list of devices. Therefore, devices can be added dynamically by an application at run time

Use the following device list

Select this option so that this Driver uses a fixed list of devices. With this option selected, user can either click Auto-detect or fill in the list of devices manually. At run time, only the devices declared on this list are used. The columns on this list are described on the table Columns on the list of devices

Add

Adds a new device on the list

Edit

Allows changing the configuration of the selected device on the list. Please check topic Add or Edit a BACnet device for more information about this option

Delete

Removes the selected device from the list

Auto-detect

Searches for BACnet devices available on the local network. Clicking this option removes the content of the list and fills it with all devices found. Please check topic Auto-Detecting Devices for more information

Use All IPs

Indicates that this Driver must send Tags to all IP addresses from the list

Use this IP

Indicates that this Driver must send Tags only to the selected IP address. This allows several instances of this Driver to send different Tags to different IP addresses

Log Detailed BACnet Packets

Enable this option so that this Driver generates, on the log file, detailed information about the received and sent BACnet packets

Auto-Detect Devices Range

Range of searched devices through auto-detection services. Please check topic Auto-Detecting Devices for more information. The default value for this property is "0-4194302"

Application Timeout (milliseconds)

Time-out for transactions with devices, in milliseconds

Wait Timeout (milliseconds)

Time-out for the link layer, in milliseconds. Default value of this option is 10000, or 10 seconds. This is the time this Driver waits to clear the communication channel. For example, when performing a writing to a device, this writing process may wait for an ongoing reading process to finish. This option defines a maximum time for this time-out. If the channel is not available is not available after waiting for this configured time, this Driver fails this operation

Retries

Allows defining a number of retries for requests that failed due to communication errors

Disable Read Grouping

Select this option so that this Driver does not use grouped readings, or readings of several Tags on the same request, nor notifications of value changes

Maximum Transactions per Network

Maximum number of simultaneous transactions on the same network. The network number of a device is determined by the Enable Network Address, Network Address, and MAC Address properties. The default value of this property is 1 (one) and the maximum value is 100

Network Delay (milliseconds)

Delay, in milliseconds, between messages sent to the same external network. This delay is not applied to messages to local or broadcast devices. The network number of a device is determined by the Enable Network Address, Network Address, and MAC Address properties. The default value of this property is 0 (zero)

COV Process Identifier

Identifier of the process executing the COV System

Read Quality-related Properties

When this option is enabled, Tags reading the PresentValue property of an object also implicitly read that object's Reliability and StatusFlags properties, which are used to determine the quality of a Tag. When this option is disabled, the quality of a Tag is determined by these properties only if they are explicitly read by other Tags. The default value for this property is True (enabled)

Driver Device Instance

Driver Device identifier. This number shall be unique among all BACnet internetwork-wide devices. This value is associated to the objectIdentifier property of the Device object. The default value for this property is 191 and the maximum value is 4194302

Driver Device Name

Driver name. This name shall be unique among all BACnet internetwork-wide devices. This value is associated to the objectName property of the Device object. The default value for this property is "Elipse BACnet Driver #191"

Maximum number of properties per ReadPropertyMultiple request

Maximum number of properties present in a multiple reading request sent by this Driver

Inter-Message Delay (milliseconds)

Delay, in milliseconds, between messages sent to the same device. Default value of this option is 0 (zero)

Use COV

Enables the system of spontaneous messages (Change of Value, or COV), sent by a device when a value changes. Please check topic COV System for more information

Use Confirmed COV

Configures a remote device to request a receive confirmation for COV (Change Of Value) packets. Used only when the Use COV option is equal to True and the Disable Read Grouping option is equal to False

Maximum COV Subscriptions

Maximum number of COV (Change Of Value) subscriptions this Driver establishes per device. When reaching this limit, all other Tags are read by polling

Exclude Analog objects from COV

When this option is enabled, readings of analog values are not performed by COV notifications

COV Subscription Lifetime (seconds)

Time, in seconds, in which a COV subscription is valid. A value of 0 (zero) indicates that a subscription does not expire. This Driver renews expired subscriptions automatically

SubscribeCOV Delay (milliseconds)

Delay, in milliseconds, between sending a request for a COV subscription and the next message to the same device. Default value of this option is 0 (zero)

Device

The identifier of this BACnet device. The icon indicates this device can be accessed by the currently configured IP address and the icon indicates this device is on an IP address different from the one configured in IOKit

IP

Shows the IP address where this device is. An instance of BACnet Driver can access only one IP address. This list's footer displays the currently configured IP address

Subnet/MAC

Shows the network and MAC address for this device, if enabled

Use COV

Shows COV (Change Of Value) settings for this device

Read Multiple

Shows the maximum number of properties present in a multiple reading request sent to this device

Write Priority

Shows the value of the priority to be used in writing requests for this device, if enabled

Alarms

Shows alarm settings for this device
