The Bacnet connector options are available from the "Option" button in the "BACnet Configuration" window:
These options are divided into several categories described below:
This group defines the polling parameters of the communication with theBACnet devices:
- Polling period:
Period (in seconds) of the polling performed to cyclically read variables that do not accept automatic subscriptions.
- Response timeout:
Maximum time waited (in milliseconds) to receive response to BACnet requests.
- Retry number:
Number of new attempts when thereis no response to a BACnet request.
- Time synchro:
Period (in seconds) of the automatic time synchronization of BACnet devices from the BACnetserver. When this value is 0 (default value), there is no time synchronization.
- Status polling:
Period (in seconds) of the polling performed to cyclically control the status of the supervised devices.
- Time detection:
Waited time (in seconds) to detect the devices on first connection.
- Time to subscribe:
Waited time (in seconds) toinitialize the subscriptions on device connection.
- Automatic device discovery:
When this box is checked, a network broadcasting is automatically performed at launching time.
This group defines the default parameters of writing operations.
The “Default writing priority” value defines the priority used by default to write a value in a device. This priority is used by all devices having their priority set to 0. Its default value is 8.
The higher priority is 1, the lower is 16. When a value has been written with a specified priority, all subsequent writing operation performed with a lower priority (higher priority value) will be denied.
Default notification options
This group defines the default treatment of notifications transmitted by the devices.
- COV notifications confirmed
This option validates the transmission of a confirmation response for every “Change Of Value” notifications received.
- Event notifications confirmed
This option validates the transmission of a confirmation response for every event notifications received.
- Refresh period of event notifications
This value defines the default period in minutes for sending the device event notification refresh request. This option allows you to periodically synchronize device event notifications in case a notification is lost.
A null value removes any periodic refresh request.
- Add device name in tag identifier
When this option is validated, the device name is added to the top of the identifier of each variable, separated by the separator defined below.
- Device separator
The default device separator in tag identifier is ":". This separator can be changed if the character ":" can be used in the device or tag name.
- Vendor extensions enabled
Check this box if the connected devices can use specific vendor extensions.
- Level of low-level traces
Define here the level of the low level traces of the BACnet stack (0 to3, -1 to disable low_level traces).
