DALI-router

For advanced functions, the Windows-based software Designer is used. Each individual router can handle two DALI circuits, each with a maximum of 64 control units and load interfaces. The system can be programmed for energy-saving functions such as occupancy detection and constant lighting. Further automatic functions are possible with planned events. The OPC server software activates interfaces with the processing system in the building.

Superb reliability

All data is stored in the system itself, the need for PC control in daily usage. Eliminating the central control arrangement ensures that no single product can cause a breakdown of the system. If necessary, a PC can be connected to the system for diagnostic purposes.

Advantages

  • No PC required for daily usage.
  • Complete flexibility.
  • Standard protocol.
  • Simple system layout.

System fundamentals

The router is the central unit in the system providing a smooth connection between a large number of DALI and DIGIDIM products.

DIGIDIM systems are programmed using Helvar’s Designer software, which can be used on a local or remote-controlled Windows-based PC. Once programming is complete, the PC can be disconnected as it is not required for normal daily system usage. The PC can also be used to monitor and report on the status of the system. All data are stored in flash memory in the DIGIDIM routers, which avoids the need for cumbersome databases and allows the system to be saved to a PC as back-up.

Network of several routers

A large number of routers can be interconnected in a network of standard Ethernet connections. This means it can be used for programming and monitoring. The extent of the system is defined as a work group. A work group is a collection of routers joined via an Ethernet connection.

DALI Router – flexible control for the major installation

 

Key figures

  • A DIGIDIM router can handle 128 DALI units.
  • Each DALI network can have 64 DALI units connected, with a maximum length of
  • 300 metres.
  • Integrated 250 mA DALI power supply for each DALI network.
  • 10/100 Mbit/s Ethernet connection with Internet protocol (TCP/IP).
  • 16.000 groups in Designer software.
  • Each router can use 256 groups.
  • DALI units work together in groups.

Functions

  • Manual control (always the option of adjusting the light in person).
  • Daylight control (adjustment according to incident daylight. Both open loop and closed loop).
  • Occupancy detection (in multi-sensor or external units).
  • Lamp status (each DALI unit can provide information).
  • Log for life span of light sources (consumption by individual light sources can be logged in a journal).
  • Automatic updating when an HF-ballast is changed (information for the removed ballast is updated in the new one).
  • Timer functions (automatic on/off or change of functions depending on time).
  • Calendar functions (events may occur on specific days of the week).
  • Automatic sequence control (e.g. daylight simulation).
  • Blocking function for corridor lighting (always corridor lighting when office is occupied).
  • Logic functions (AND & NAND-like functions).
  • Automatic control of emergency lighting units (meets the DALI standard for the control of emergency lighting units).
  • OPC functions (control between property systems and servers).
  • Multiple offset controls (constant light adjustment provides higher level of lighting away from windows).
