x/bacnetWrite component: v0.37.0+ BACnet/IP writes object properties (present-value of analog-output/binary-output/multi-state-value), routing to Success/Failure.

Requires: rulego-components-iot (opens new window)

Configuration

Field	Type	Description	Default
server	string	Device address host:port, default port 47808	127.0.0.1:47808
timeout	int	Request timeout (seconds)	5
priority	int	Write priority 1-16, 0=omit (device default)	0
points	array	Control point table (addr=object address, type=value type, value=write value)	see below

Point Table Fields

Field	Description	Example
name	Point name	Setpoint
addr	Object address: objectType:instance[:property]	analog-output:0
type	Value type: FLOAT32/FLOAT64/BOOL/ENUM/STRING/INT32/UINT16	FLOAT32
value	Write value (string form)	18.5

type selects the BACnet application data type for the write:

• FLOAT32/FLOAT64: analog-output (real/double)
• BOOL: binary-output
• ENUM: multi-state-value
• STRING: string property

All fields support ${msg.xx} / ${metadata.xx} templates.

Input/Output

• Input: msg.Data with point list JSON [{"addr","type","value"}]
• Output: passes the message through on Success

Example

{
  "id": "bacnet_write",
  "type": "x/bacnetWrite",
  "configuration": {
    "server": "192.168.1.10:47808",
    "timeout": 5,
    "priority": 8,
    "points": [
      {"name": "Setpoint", "addr": "analog-output:0", "type": "FLOAT32", "value": "${msg.setpoint}"}
    ]
  }
}

Dynamic write (msg.Data with point list):

[{"name": "Fan", "addr": "binary-output:1", "type": "BOOL", "value": "true"}]
