2. Introduction

Introduction

Update: Tc3_DALI library The Tc2_DALI TwinCAT 3 PLC library is the predecessor to Tc3_DALI. We recommend using the Tc3_DALI library. The Tc2_DALI library will no longer be updated in future. The Tc2_DALI library should not be used for new projects. All the functionalities of the Tc2_DALI library are also available in the new Tc3_DALI library.

The user of this library requires basic knowledge of the following:

• TwinCAT XAE
• PC and network knowledge
• Structure and properties of the Beckhoff Embedded PC and its Bus Terminal system
• Technology of DALI devices
• Relevant safety regulations for building technical equipment

This software library is intended for building automation system partners of Beckhoff Automation GmbH & Co. KG. The system partners operate in the field of building automation and are concerned with the installation, commissioning, expansion, maintenance and service of measurement, control and regulating systems for the technical equipment of buildings.

The Tc2_DALI library is usable on all hardware platforms that support TwinCAT 3.1 or higher.
