Elsner

The Elsner P03/3-MODBUS is a solid-state weather station with a standard Modbus RTU slave interface. It measures temperature, wind speed and brightness (eastern, southern and western sun) and recognizes precipitation.

Communication

The P03/3 has a Modbus interface. The default connection parameters are:

• Modbus address: 1

• RS-485 parameters:

Baud rate	19200
Data bits	8
Stop bit	1
Parity	even
Flow control	none

Refer to the P03/3 data sheet for installation, wiring and power supply requirements.

HSYCO Configuration

Add an ELSNERP03M I/O Server in the I/O Servers section of the Settings and set its parameters:

Communication

• Comm ID: select a MODBUSTCP I/O server if using a Modbus gateway, or the serial port id when using a direct RS-485 port with HSYCO acting as Modbus RTU master.

High Availability

• Shutdown when inactive: defaults to true.

Options

ID	Default	Values	Description
gui	true	true	enable support for the UI object, UISET actions and USER commands
		false	disable UI support
startupevents	false	true	generate IO events also during the driver’s start-up phase
		false	start generating events only after HSYCO is aligned with the current status of the system
pollinterval	30	> 1	the data acquisition interval, in seconds
address	1	> 1	the Modbus address of the P03/3 device

Datapoints

ID	Value	R/W	Description
connection	online	R	connection established to the P03/3
	offline	R	HSYCO can’t connect to the P03/3
temp	signed integer -40C .. +80C	R	signed integer representing the measured temperature, in 10th of Celsius degrees (e.g. 210 corresponds to 21.0C)
light	positive integer 0 .. 99	R	ambient light in kilolux, equal to the maximum value detected by the three side sensors
light.east	positive integer 0 .. 99	R	ambient light in kilolux, detected from East-side sensor
light.south	positive integer 0 .. 99	R	ambient light in kilolux, detected from South-side sensor
light.west	positive integer 0 .. 99	R	ambient light in kilolux, detected from West-side sensor
wind	positive integer	R	wind in 10th of m/s (e.g. 32 corresponds to 3.2 m/s)
rain	0	R	no rain
	1	R	rain

User Interface

UISET Actions

ID	Attribute	Set to
temp	value	the current temperature in Celsius degrees with one decimal digit, followed by " °C"
light	value	the current ambient light in Klux, followed by " Klux"
wind	value	the current wind in m/s, followed by " m/s"
