BACNET

The BACNET object corresponds to the BacNet system object.

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:

OnEvent("BACNET","_id_","_event_")

BACNET object events description:

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 :

DoReact("BACNET","_id_","_command_" [,"_parameters_"]);

The list of commands and parameters for 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

Examples

The examples code is given in JScript, see The Script object. Programming using the JScript language

Write to an object using a script

var msg = CreateMsg();

//bacnet_application_tag
var BACNET_APPLICATION_TAG_NULL = 0;
var BACNET_APPLICATION_TAG_BOOLEAN = 1;
var BACNET_APPLICATION_TAG_UNSIGNED_INT = 2;
var BACNET_APPLICATION_TAG_SIGNED_INT = 3;
var BACNET_APPLICATION_TAG_REAL = 4;
var BACNET_APPLICATION_TAG_DOUBLE = 5;
var BACNET_APPLICATION_TAG_OCTET_STRING = 6;
var BACNET_APPLICATION_TAG_CHARACTER_STRING = 7;
var BACNET_APPLICATION_TAG_BIT_STRING = 8;

//bacnet_objtype
var OBJECT_ANALOG_INPUT = 0;
var OBJECT_ANALOG_OUTPUT = 1;
var OBJECT_ANALOG_VALUE = 2;
var OBJECT_BINARY_INPUT = 3;
var OBJECT_BINARY_OUTPUT = 4;
var OBJECT_BINARY_VALUE = 5;

//bacnet_property_id
var PROP_PRESENT_VALUE = 85;

msg.StringToMsg("BACNETINT|1|WRITE");
msg.SetParam("bacnet_application_tag", BACNET_APPLICATION_TAG_UNSIGNED_INT);
msg.SetParam("bacnet_value",30);

msg.SetParam("bacnet_objtype",OBJECT_ANALOG_VALUE);
msg.SetParam("bacnet_instance",0);

msg.SetParam("bacnet_property_id",PROP_PRESENT_VALUE);
msg.SetParam("bacnet_device_id",12345);

DoReact(msg);

In case of successful script execution, an event will appear in the Debug window

Event : BACNETINT|1|WRITE_OCCURES|sender<Udp:47808>,slave_id<ASUS>,fraction<186>,invoke_id<43>,owner<ASUS>,module<bacnetint.vshost.exe>,date<27-11-18>,value<PROP_PRESENT_VALUE>,guid_pk<{E23BD6CB-19F2-E811-8B83-C860008A29F9}>,object_id<OBJECT_ANALOG_VALUE:0>,core_global<1>,adr<192.168.0.197:56747>,time<10:55:33>,source_guid<557367ce-19f2-e811-8b83-c860008a29f9>

Generate event

DebugLogString("Script2");
var msg = CreateMsg();


msg.StringToMsg("BACNETINT|1|EVENT");

msg.SetParam("event_type", "0");
msg.SetParam("from_state", "1");
msg.SetParam("to_state", "0");

msg.SetParam("message_text", "test_text1!");

DoReact(msg);

If the module receives an event, the following event will be displayed in the Debug window:

Event : BACNETINT|1|EVENT_OCCURES|sender<Udp:47808>,slave_id<ASUS>,fraction<683>,owner<ASUS>,event_type<EVENT_CHANGE_OF_BITSTRING>,module<bacnetint.vshost.exe>,message_text<test_text1!>,date<27-11-18>,guid_pk<{6D34BA08-1CF2-E811-8B83-C860008A29F9}>,from_state<EVENT_STATE_FAULT>,core_global<1>,adr<192.168.0.197:57878>,to_state<EVENT_STATE_NORMAL>,time<11:11:34>,source_guid<bd51a40d-1cf2-e811-8b83-c860008a29f9>

Read indicators from an object

msg.SetParam("bacnet_property_id",PROP_PRESENT_VALUE);
msg.SetParam("bacnet_device_id",123456);
DoReact(msg);

In case of successful reading, the following event will be displayed in the Debug window:
