Tridonic

Tridonic is a lighting system based on the DALI bus technology. HSYCO integrates this system and communicates with it through the DALI SCI2 interface module and its communication protocol. The integration relies on a direct connection between the DALI SCI2 interface and HSYCO server’s RS-232 serial port, or through a TCP/IP to serial port gateway.

Communication

The DALI SCI2 interface module communicates with HSYCO through a RS-232 interface.

RS-232 parameters:

Baud rate	38400 bps
Data bits	8
Stop bit	1
Parity	none

Further, the RS-232 signals RTS and DTR must be set to the following levels: RTS = +6 ... +12 V DTR = -6 ... -12 V Refer to the SCI2 manual for installation, wiring and power supply requirements.

Tridonic Configuration

On one BUS, there can be up to 64 dimmers, addressed from 0 to 63, organized in up to 16 groups (0 - 15) or individually addressable. The driver also includes the support for the MSensor 2.0 motion detector and photometer functionalities. The MSensor 2.0 can be configured to work in two different modes:

- Direct-master mode (default mode): The MSensor has a DALI address and sends motion detection and light regulation commands to the group specified by its rotary switch (if the switch is set on the value X the controlled group will be X - 1, if the switch is set on “0” the commands are broadcasted). The light intensity value measured by the light sensor is only read upon request (see I/O Events API)

- Indirect-master mode: The MSensor doesn’t have a DALI address and does not control any dimmer directly. The motion detector and the light sensor have two different eDALI (extended DALI) addresses from which they send motion and light intensity asynchronous events.

HSYCO Configuration

Options

ID	Default	Values	Description
discovery	true	true	auto-detects all DALI devices and groups, and automatically lists them in the systemtopo.txt file
		false	auto-detect for devices is disabled
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
broadcastrange	1...254	<min>-<max>	specifies the minimum <min> and maximum<max> allowed light levels for the broadcast command
groupsrange	g<n>:1...254	g<n>:<min>-<max>	specifies the minimum <min> and maximum<max> allowed light levels for the group <n>. If more than one group range is to be specified, then list the ranges separated by “;”, e.g. groupsrange=g0:20-254;g1:40-250
luxdelta	0	≥ 0	option for MSensors. Specifies the minimum difference between light intensity readings required to generate a new event. I.e. when a “xxx.lux” event is generated, a new event (from the same sensor) will be generated only if the new value is greater than the old value plus the luxdelta value or smaller than the old value minus the luxdelta value

Note 1 

Only available if the MSensor is configured to work in Direct-master mode (default mode).

Note 2 

Only available if the MSensor is configured to work in Indirect-master mode.

Note 3 

The 2-byte DALI frames consist of an 8-bit address part and an 8-bit command part.

The address byte is formatted as follows:

Type of Address	Byte Description
Individual address	0AAAAAAS (AAAAAA = 0 .. 63, S = 0/1)
Group Address	100AAAAS (AAAA = 0 .. 15, S = 0/1)
Broadcast Address	1111111S (S = 0/1)

The command byte is to be interpreted as an arc power level (light intensity) if bit S is 0. The arc power can range between 00 (off) and and FE (maximum level) expressed in hexadecimal. A 1 in the position S means that the command byte is to be interpreted as a DALI command. Refer to the following table for a list of all available commands:

Command	Description
00	Extinguish the lamp without fading
01	Dim up 200 ms using the selected fade rate
02	Dim down 200 ms using the selected fade rate

Other than the above described commands, it is possible to send the following 2-byte DALI frames:

Frame	Description
A100	All special mode processes shall be terminated	A3XX	Store value XX in the DTR
A5XX	Initialize addressing commands for slaves with address XX
A700	Generate a new random address
A900	Compare the random address with the search address

B7XX	Program the selected slave with short address XX
B9XX	Check if the selected slave has short address XX
BB00	The selected slave returns its short address XX
BD00	Go into physical selection mode

The value of the events ID.command and ID.monitor is expressed as a 4-digits string “XXYY” representing the hexadecimal value (upper case letters) of the two bytes. For instance, to send the command 00 to the group 1 of our system “tr”, the following syntax will apply: tr.command = 8300

User Interface

Aton Object

The user interface for the Aton multi-room system:

The Aton object is listed in the Project Editor’s new object list only when at least one Aton I/O Server is defined.

Parameters

• server id: the server ID
• module:
• zone: zone number of the Aton multi-room system (max 12 zones)
• position: the object's position. Use the pixels or rows and columns coordinates format

Syntax

(aton <server id>; <module>; <zone>; <position>)

E.g.

(aton serverid; module; zone; x10y20)

UISET Actions

ID	Attribute	Set to
connection.label.online	visible	true	when datapoint connection = online
		false	when datapoint connection = offline
connection.label.offline	visible	true	when datapoint connection = offline
		false	when datapoint connection = online

USER Commands

To send a user command to the I/O Server just set the name to the ID of a writable (W) datapoint and the parameter to one of the possible values.

For instance, setting the name of a user button to “aton.z1.power” and its param field to “flip”, will result in having a switch for zone 1. Naming it “aton.z1.source” with a valid source as param (e.g. “1”, “2”, or “R1”) will result in a button for setting the audio source of the zone.
