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 |
The Device Configuration Database
The systemtopo.txt file contains the list of all dimmers, groups and the broadcast address that could be directly associated to graphic objects in the Web-based user interface. This file can be filled manually or automatically by HSYCO at start-up. To enable automatic discovery and automatic generation of devices’ information in the systemtopo.txt file, use the discovery option in the hsyco.ini configuration file. This is an example of an automatically generated systemtopo.txt file:
(devices) tr.0 : LIGHT ; DIMMER ; tr.1 : LIGHT ; DIMMER ; tr.2 : LIGHT ; DIMMER ; tr.g1 : LIGHT ; DIMMER ; DALI group [1,2] tr.g4 : LIGHT ; DIMMER ; DALI group [0,1] tr.broadcast : LIGHT ; DIMMER ; DALI broadcast
You should then manually add comments and other optional parameters:
(devices) tr.0 : LIGHT ; DIMMER ; door tr.1 : LIGHT ; DIMMER ; corridor 1 tr.2 : LIGHT ; DIMMER ; corridor 2 tr.g1 : LIGHT ; DIMMER ; DALI group [1,2]; corridor group tr.g4 : LIGHT ; DIMMER ; DALI group [0,1]; entrance group tr.broadcast : LIGHT ; DIMMER ; DALI broadcast

- 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 |

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 |
| AB00 | Withdraw from the compare process |

| 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
All the devices that have been defined in the systemtopo.txt database are automatically listed in the Web Editor. Adding a slider to control a dimmer requires just a few clicks and no additional EVENTS logic.
