Siemens 6BK1621-0AA00-0AA0 SIMATIC PN/BACnet LINK PROFINET to BACnet/IP Gateway IP20 Automation Component

The Siemens 6BK1621-0AA00-0AA0 SIMATIC PN/BACnet LINK is a coupling module that bridges PROFINET to BACnet/IP fieldbus traffic, implementing the B-GW device profile at IP20. It runs PROFINET IO Device with an integrated 2-port switch on one side and a BACnet/IP interface supporting 1,000 objects and 1,000 subscription services on the other, powered from a 24 V DC supply.

Selection Notes

The B-GW device profile means this module acts as a routing gateway rather than a simple BACnet client: it exposes PROFINET IO process data as BACnet objects for a building management system while keeping the PROFINET side on its own integrated 2-port switch for line topology. The 10 ms mains-buffering time and reverse-polarity/overvoltage/short-circuit protection on the 24 V DC input let it sit on a shared control-cabinet supply without extra conditioning. Choose it specifically for PROFINET-to-BACnet/IP integration; it is not a general PROFINET switch or repeater.
