One Segment with Management Platform

Management platform and Desigo automation stations are available in the same IP segment and without an additional router on the network. Only IP automation stations are integrated on the BACnet network.

Two Segments with Management Platform as FD

Management platform and Desigo automation stations are available on different IP segments. The management platform is entered as a participant in the FDT (Foreign Device Table) on the automation station using the FD (Foreign Device). Only IP automation stations are integrated on the BACnet network.

Three Segments with BBMD and Management Platform as FD

Management platform and Desigo automation stations are available on different IP segments. The management platform is entered as a participant in the FDT (Foreign Device Table) on the automation station for IP segment 2 using the FD (Foreign Device). The data exchange between IP segments 2 and 3 occurs using BBMD with automation stations 11 and 21.  Only IP automation stations are integrated on the BACnet network.

Three Segments with Management Platform as FD

Management platform and Desigo automation stations are available on different IP segments. The management platform is entered as a participant on the automation stations for IP segments 2 and 3 using BBMD. The data exchange between IP segments 1, 2, and 3 occurs using BBMD with the management platform and automation stations 11 and 21.  Only IP automation stations are integrated on the BACnet network.

BACnet Router and Management Platform as FD

Management platform and Desigo automation stations are available on the same as well as on different IP segments. The management platform is entered as a participant in the FDT (Foreign Device Table) on the automation station for IP segment 2 using the FD (Foreign Device). The data exchange between IP segment 100 and 2 occurs using BBMD via the BACnet router for network 100 and 3.  The IP automation stations are integrated directly on network 100. The automation stations for networks 1 and 3 are integrated over a BACnet router; devices for network 2 over a MS/TP-BACnet router.

Multiple Sites with Management Platform as FD

Management platform and Desigo automation stations are available on different IP segments and different locations in your network. The management platform is entered as a participant in the FDT (Foreign Device Table) on the automation station using the FD (Foreign Device). This topology is often used when connecting different site on your company network. In that case, you must setup different driver for each location. Only IP automation stations are integrated on the BACnet network.

NOTE:
Only Intranet connections are allowed for different locations.
