TwinCAT ADS Reference

This first section is an introduction into the Beckhoff ADS technology. ADS stands for "Automation Device Specification" and describes a device- and Fieldbus-independent interface. This interface got designed by Beckhoff and is - including the protocol - in detail documented.

For integration into own applications resp. compilers and tools based on Microsoft Windows Operating systems (NT / Windows 2000 / XP / Vista .. and CE) there are ADS components (ADS-OCX / DLL / NET / ...) available from Beckhoff, free of charge.

The ADS components get installed together with TwinCAT and can be found in the following directory "..\TwinCAT\Ads Api". Additionally, all named components are also available in the free of charge TwinCAT Supplement product „TwinCAT ADS Communication Library" (only exception is the ADS-OCX which belongs to the core components of TwinCAT).
