The BACNET object corresponds to the BacNet system object.
BACNET object events description:The BACNET object generates events listed in the table below. Procedures start when the corresponding event occurs. The format of the event procedure for the BacNet object:
| Code Block |
|---|
OnEvent("BACNET","_id_","_event_") |
| Event | Description |
| ERROR | Error message received |
| EVENT_OCCURES | Message acknowledgment |
WRITE_OCCURES | Recording confirmation |
| WRITE_RESULT | Recording result |
Operator format for describing actions with the BacNet object :
| Code Block |
|---|
DoReact("BACNET","_id_","_command_" [,"_parameters_"]); |
The list of commands and parameters for the the BACNET object is presented in the table.
| Command – description | Parameters | Parameters description |
WRITE – send value to BACnet device | bacnet_application_tag<> | Data type. Possible values: NULL = 0 BOOLEAN = 1 UNSIGNED INT = 2 SIGNED INT = 3 REAL = 4 DOUBLE = 5 OCTET STRING = 6 CHARACTER STRING = 7 BIT STRING = 8 |
bacnet_value<> | Parameter value | |
bacnet_objtype<> | Object type: ANALOG INPUT = 0 ANALOG OUTPUT = 1 ANALOG VALUE = 2 BINARY INPUT = 3 BINARY OUTPUT = 4 BINARY VALUE = 5 | |
bacnet_instance<> | BACnet unique global device identifier | |
bacnet_property_id<> | Property id | |
bacnet_device_id<> | BACnet device id in the system | |
| EVENT – send message to BACnet device | event_type<> | Event type |
from_state<> | Change state from | |
to_state<> | Change state to | |
message_text<> | Event text |
