SIMATIC PN/BACnet LINK network transition from Profinet to BACnet/IP networks, device profile: B-GW, IP20 As an independent component, the SIMATIC PN/BACnet LINK forms a seamless transition between PROFINET and a BACnet/IP network. BACnet devices can thus be easily connected to a PROFINET network in order to communicate with SIMATIC components. This opens up a wide range of possibilities for the simple implementation of modern production concepts, even for existing systems and machines.
