Product Overview

The 6BK1621-0AA00-0AA0 is a SIMATIC PN/BACnet LINK coupling module manufactured by Siemens. It functions as a gateway between PROFINET and BACnet/IP networks within the PN/BACnet LINK family. Configurable via STEP 7 in TIA Portal (from version V14 SP1 onward), it provides communication translation in building automation or industrial control architectures. Typical applications include integration of building management systems with PROFINET-controlled networks, IP-based device interfacing, and real-time monitoring across protocols. 6BK1621-0AA00-0AA0 supports firmware updates and I&M data handling, making it suitable for modern control environments.
