General Functionality

4.3. General Functionality
This Intesis IN703DAL0640000 gateway enables data exchange between installations and devices based on the
DALI protocol and control systems based on BACnet or Modbus.
To do so, the gateway is continuously aware of both sides: the control system (supervisor, BMS, client device,
etc.) and the DALI installations or devices to be integrated. The gateway obtains updated readings for the points
configured in it. With every read, the new values are updated in the gateway's memory and become available
for the control system side. When a change in any point configured as output in the gateway is detected (that is,
written from the control system side), the corresponding action in the DALI device is performed.

NOTE
1
We recommend limiting this number to 16 when integrating push buttons. Realize that push
buttons with several instances consume several signals.
The maximum number of DALI devices (ECGs and/or input devices) depends on the sum of the
specific devices' current consumption. The gateway supplies 230 mA to the bus to power the DALI
devices, so if each input device (sensor) in the bus consumes 5 mA, then we can connect 63 ECGs
(the standard defines the maximum consumption allowed for these devices is 2 mA) and 16 sensors.
63 ECGs * 2 mA + 16 sensors * 5 mA = 206 mA < 230 mA * 90%
As the standard recommends, don't use the guaranteed current to calculate the maximum number
of DALI devices, but leave 10% of the current for future expansion or tolerances.

This is the gateway's total number of signals regardless of whether they are ECGs, sensors, groups,
etc.
