iSMA CONTROLLI iSMA-B-AAC20 Dali Controller

Introduction

This manual contains information about the DALI network in the ISMA-B-AAC20 controller. DALI is an abbreviation for Digital Addressable Lighting Interface. DALI is a protocol in which DALI devices communicate with each other. In other words, DALI is the language in\ which DALI- devices talk to each other. DALI (Digital Addressable Lighting Interface) is a two-way communication system that brings digital technology to lighting. An international standard for communication, DALI defines the commands that ballasts need to recognize in order to be considered DALI ballasts. The system allows individual ballasts to “talk” to the user, and it allows the user to “talk” back via DALI controllers, computers equipped with appropriate software, or building management systems (BMS).

WARNING: Before programming the ISMA DALI kit please check if you are using the latest kit version. The latest kits are available on the ISMA CONTROLLI support web site ismacontrolli.com

DALI License and Limitation

In a standard license, there are available 64 DALI devices, and this number cannot be expanded. The ISMA-B-AAC20-D has an internal power supply (default switch off in network configuration) of 130 mA, which can be used to power up, up to 64 standard DALI ballasts (64 * 2 mA = 128 mA only ballasts). However, in order to connect devices, where the rate of total power consumption exceeds 130 mA (some DALI sensors use more than 2 mA), then the internal power supply must be switched off, and the external power adapter needs to be connected.

Installation of iSMA DALI Kit

The ISMA-B-AAC20-D controller has one independent DALI kit. To install the ISMA DALI kit, import the kit to the ISMA Tool software (possibly as part of the package of various kits in a zip file).

DALINetwork

This section provides a collection of procedures to use within the iSMA-B-AAC20-D DALI Network kit to build a network of devices with DALI points. The ISMA-B-AAC20-D device has one DALI interface which can be used to communicate with up to 64 DALI devices. The DALI Network kit consists of 11 types of components: And:

• DALIDevice;
• DALIDeviceFolder;
• DALILogicFolder;
• DALINetwork.

DALI Network Component

The DALINetwork component is the main component, which services the DALI physical interface. The component must be placed under the Drivers folder.

The DALINetwork component has the following slots: Status: Network’s status;

• Available states: OK (network is working properly), Disabled (network is disabled, the Enable slot is in false), OK some device/point down (error in the device or points); Fault Cause: fault cause description;
• Enable: this option switches on or switches off the DALI network; true (network enabled), false (network disabled);
• Last Discovery Time: indicates the last time the devices on the DALI network have been discovered;
• Power Supply: switches on/off the DALI Network power supply.

Note: As part of the DALINetwork component, configuration actions performed by the integrator (Discover or ReadDevice and WriteDevice of the DALI Device component) have a common context. By doing this action during the implementation of another action, theprevious action will be interrupted, and the new action will be started. The communication acquisition status is not shown in any way (status slot or console); therefore, depending on the DALI communication speed set, the integrator must allow a certain time to execute the command and start the next command after that time.

The DALINetwork component has two actions

Discover: This action will automatically search and detect all devices connected to a DALI port. It will also create a Discover folder and place there all found devices. All devices have a unique address assigned by the manufacturer (slot Address). All devices can be moved and grouped into Device Folders (folders must be also placed under the DALINetwork component).
Discover New Initialization: This action has the same functionality as ‘discover’, but is also responsible for Short Address. After using this action the Short Address will be grouped from 0–63, and it will erase your previous addresses (this action is recommended at the first commissioning process).

Special Views

Two special views are available for the DALINetwork component in the ISMA Tool: DALI Group Manager and DALI Device Manager. The DALI Group Manager The DALI Device Manager list all discovered DALI devices in the network, their addresses, and statuses.

DALIDevice

The DALIDevice is responsible for servicing physical devices connected to the DALI network. Each device is represented by a DALI device component and has a unique DALI address (0 to 63).

The DALIDevice component has the following slots

• Status: shows the device current status;
  Fault Cause: fault cause description;

• Description: additional description label;

• Device Type: indicates the type of device;

• Short Address: defines the address at the planning stage;

• Random Address: hexadecimal address of a device connected to the DALI input controller;

• Read Actual Level: current brightness value of the ballast;

• Read Device Status: shows the actual status of the device;

• Group (0-15): a transition from false to true will cause the associated scene selected command to be sent to the control gear;

• Scene (0-15): stores the brightness values for the individual scenes;

• Max Level: sets the maximum brightness value–this value cannot be exceeded when fading up;

• Min Level: sets the minimum brightness value–this value cannot be undershot when fading down;

• Power On Level: brightness value to which extent the DALI ballast switches when the power supply is switched on;

• System Failure Level: brightness value to which extent the DALI ballast switches when a fault is detected in the DALI circuit;

• Fade Time: time in seconds of fading from the current brightness value to the new brightness value;

The DALIDevice component has the following actions

• Read: reads the configuration data and the current status of the device;
• Write: writes the configuration data and the current status of the device;
• Blink: allows the light source(s) of the device to flash.

DALI Groups and Scenes

DALI Groups

With the DALIDevice it is possible to define 16 groups in a DALI circuit. A group is a number of devices classed together. The Group assignment can be edited in the DALIDevice component. It is possible for one DALI device to belong to several groups. This reduces the amount of wiring needed and greatly increases flexibility compared with non-addressable systems because in these systems the groupings are hard-wired.

DALI Scenes

With the DALIDevice component it is possible to store 16 different lighting scenarios in each DALI device so that predefined lighting moods can be called up for a room (for example, the “presentation” scene in a conference room or a “morning” scene in a wellness center). The values of the 16 scenes are stored in the control gear. ****

DALICommand

While defining a function, numerous parameters can be set to select the destination address for which the function is intended (group or individual address) and the type of the DALI command to be performed. The DALI protocol allows addressing an individual control gear (ballasts, relays, dimming circuits, etc.) without a need to refer to a parent device. The DALICommand is used for triggering the DALI commands. Individual In slots are provided for various DALI commands. A transition from false to true will cause the associated DALI command to be sent to the control gear.

Slots

The DALICommand has the following slots:

• Status: shows the component’s current status;
• Description: user description up to 32 characters;
• Command: parameter to a control gear;
• Address: short DALI device address or DALI group address;
• Address Type: option to define a single device, group, or all DALI devices;
• Value: intensity values for scenes;
• Trigger: the rising edge sends the DALI command to DALI devices.

Action

The DALICommand component has the following action:

• Send: sends the DALI command to DALI devices.

DALI On/Off

• This component has a built-in DALI command, which will be sent to DALI devices/devices on the rising edge of slots on and off.

Slots

The component has the following slots:

• Status: shows the component’s current status;
• Description: user description up to 32 characters;
• Address: short DALI device address or DALI group address;
• Address Type: option to define a single device, group, or all DALI devices;
• On: the rising edge sends the Switch On command to device/devices;
• Off: the rising edge sends the Switch Off command to the device/devices.

Actions
The DALIOnOff component has the following actions:

• Send On: sends the Switch On command to DALI device/devices;
• Send Off: sends the Switch Off command to DALI device/devices.

DALI On /Off Dimming 1 Switch

This component has a built-in DALI command, which allows switching on and off or to change the DALI device/device lighting level. This component is designed to work with a single switch (one button connected to one digital input). The switch is working in two modes, short and long press. The short press (if the Switch slot is in the true model for the time shorter than defined in the Long Press slot) triggers a toggle function, so each short press sends an on/off command to the DALI device/devices. The long press is to increase or decrease the lighting level. Each press toggles between the increase or decrease function. The current lighting level is stored in the device in the scene number defined in the Scene No For Last Level slot (by default, scene no. 15). The short press on command invokes the lighting level stored in this scene. The component knows how to perform the next action based on the actions previously performed on it, therefore, it is not suitable to connect it with other components affecting the same ballast (whether by Address Type Single or Group, or All). Each action performed on a ballast by another component causes the action to desynchronize in the DALI On Off Dimming 1 Switch.

Slots
The DALIOnOffDimming1Switch component has the following slots:

• Status: shows the component’s current status;
• Description: user description up to 32 characters;
• Address: short DALI device address or DALI group address;
• Address Type: option to define a single device, group, or all DALI devices;
• Switch: component input which triggers the DALI command sending;
• Long Press: time parameter which defines the time for the long press function, (by default, 500 ms);
• Scene No For Last Level: sets the scene number, which stores the last level value (by default, scene no. 15).

Action
The DALI On/Off Dimming 1 Switch component has the following action:

• Send Short Press: toggles between on and off commands and sends it to DALI devices/ devices.

DALI On/Off Dimming 2 Switch

This component has the built-in DALI command, which allows switching on and off or to change the DALI device/device lighting level. This component was designed to work with a double switch (one button for switching on and dimming up, second for switch off and dimming down). The switch is working in two modes, short and long press. The short press (if the Switch slot is in the true model for the time shorter than defined in the Long Press slot), triggers an on/off command to the DALI device/devices. The long press is for increasing or decreasing the lighting level. The current lighting level is stored in the device in the scene number defined in the Scene No For Last Level slot (by default, scene no. 15). The short press On command will recall the lighting level stored in this scene. The component does not check the actions it has performed recently, it only performs actions determined on the basis of triggering the corresponding inputs, therefore it is suitable to connect it with other components affecting the same ballast (whether by Address Type Single or Group, or All).

Slots
The DALIOnOffDimming2Switch component has the following slots:

• Status: shows the component’s current status;
• Description: user description up to 32 characters;
• Address: short DALI device address or DALI group address;
