Function
ABA/S 1.2.1 | 2CDC509086D0201 21
4 Function
4.1 Overview
The device provides a comprehensive range of logic functions.
It requires an auxiliary voltage, either 24 V DC or Power over Ethernet (PoE). We recommend using a
power supply from our range. When using timer functions, date and time must be provided via KNX/TP.
4.2 Functional overview
This device provides extensive logic functions, which extends the use of KNX to new applications.
The logic engine is generated via a graphic UI integrated in ETS as a plug-in. This provides up to 3,000
logic gates. There is a simulation function for testing generated logic.
User-defined function blocks can be created and saved for use in other projects.
An integrated web server allows you to enter and display up to 60 values.
This function is very basic and is not a substitute for a real visualization.
An internal backup allows the device to continue operating for at least 5 seconds but typically up to 20
seconds in the event of a power failure (24 V DC or PoE). This allows the device to operate normally
during a brief voltage drop.
The device is programmed via a KNX/TP bus or IP network.
During KNX/TP programming, extensive logic functions may take a long time to download.
