Overview 3 General 3 Overview There is a different approach in room automation with regard to flexibility, sizing, use, and reuse versus on primary plants, for example, air handling. Functions are required here to centrally switch all rooms with a specific room state through the entire floor or switch lighting in rooms at a specified time. The same applies to shading systems that deploy the blinds to a safe position during high winds based on a weather station.
3 Overview General 3.1 General The first and most costly mistakes are already made during the planning phase. It is not uncommon to submit faulty bids or bids that are not understandable. Planning offices generally fail to provide clear answers to detailed queries since the requisite knowledge on networks is often lacking. Pay close attention to the section on network and communications if a tender is involved.

Overview 3 General Commanding Designing a system Distribution/commanding of group masters to group member Restricted to max. 500 group members Moreover, the same concept can be used to compile demand signals for chilled water, hot water, or for air handling. Demand occurs in room segments assigned to a group; it is collected, evaluated and transmitted to generation via the applicable group master.

These devices must be networked together. Preliminary clarifications must define the number of room automation stations, automation stations for primary plants and superposed functions as well as central functions are required and how they are distributed.

3 Overview Networking Ethernet/IP networks Edge switches The end devices are connected here. They are located at the end of the network in the control cabinets. They are typically unmanaged layer 2 switches; managed layer 2 switches when setting up VLANs. Layer 2 and layer 3 switches Layer 2 switches (Ethernet switches) only take the Ethernet MAC address into account when transmitting a data packet. No additional configuration required.
Overview Networking Ethernet/IP networks 3 Port-based VLANs Switch A 1 5 2 6 3 7 4 8 AS01 AS02 AS03 AS04 Port-based VLANs distribute a virtual managed switch to multiple switches. Each VLAN is identified by a VLAN-ID between 1 and 4094 with VLAN-ID 1 reserved as the default VLAN. The switch's IP address is exclusively reachable via ports that are fixed on this VLAN.

Managed Layer 2 Switches with Rapid Spanning Tree Protocol It is not enough to plan and implement the proper network technology to guarantee reliability and availability. Switches with two voltage inputs are commonly offered to increase availability. Alarm messages can also be sent over hardware relay contacts (for example, in the event a connection or power supply fails, etc.).
Overview 3 Networking BACnet network For detailed information, see Desigo Ethernet, TCP/IP, MS/TP and BACnet (CM110666) and Practical guide on IP networks in building automation and control (CM110668). 3.3 Networking BACnet network The topics of IP networks and BACnet merge when networking BACnet networks. Standard knowledge of planning and implementation suffice for small to mid-sized projects.
Overview Networking BACnet network 3 projects, especially with Desigo room automation, operate with asymmetrical BDT entries. To this end there is a designated BBMD (Building Scope) that knows all other BBMDs, but where the other BBMDs only know these special BBMD. For detailed information, see Desigo Ethernet, TCP/IP, MSTP and BACnet (CM110666) and the following sections and practical examples. In the Desigo system, the PXG3.L and PXG3.M as well as all PXC...
Overview 3 Merging BACnet/IP networks A broadcast is sent when starting up a BACnet client, for example, Desigo CC. This is necessary since this BACnet participant is located in a remote IP segment and must registered on the network as a third-party device. Its broadcast is recognized on the BBMD for the new network, packed, and sent to all participants entered in the BBMD. BBMDs in other IP segments recognize this and send the Unicast as broadcast to all participants in its segment.

4 BACnet/IP networks BACnet referencing over different IP networks 4.3 BACnet referencing over different IP networks A common exception is the necessity to provide an individual data point to multiple locations in the building. One example is a weather station where the value is required on all BACnet networks. A coupling of BACnet networks via BBMDs for just this one data point is possible, but costly. As a consequence, Desigo V6.
BACnet/IP networks 4 Diagnostics and troubleshooting BACnet/IP networks 4.4 Diagnostics and troubleshooting BACnet/IP networks General procedure for diagnostics and troubleshooting BACnet on IP involves the use of a large number of components and this results in a certain degree of complexity and a corresponding vulnerability to errors. If a problem arises in the system, it must be located in a step-by-step procedure. Always start you analysis at the lowest system.
5 BACnet networks with MS/TP trunks Designing BACnet networks with MS/TP trunks 5 BACnet networks with MS/TP trunks 5.1 Designing BACnet networks with MS/TP trunks MS/TP is Master-Slave/Token-Passing and stands for the BACnet data link protocol with services based on EIA-485 as the physical layer. It permits simple cabling on site with 3 wires up to a max. cable length of 1200 meters. The logical principle behind MS/TP is the token passing, i.e.
BACnet networks with MS/TP trunks MS/TP cabling and topology 5 5.2 MS/TP cabling and topology Physically, an MS/TP bus is a line topology, even if it is logically a ring (due to the token passing principle). The following applies: ● The MS/TP network may only be implemented within a building. ● BACnet MS/TP networks may only be wired in a line topology. T connections/branches are prohibited. Stub lines are one exception (up to a maximum of 30 meters).
