Group address / Binding
A group address / binding is a connection of network variables of the same type between different nodes.
The group addresses / bindings are generated using ETS (EIB tool software) when designing the KNX/EIB
network. The bound network variables communicate when changing the value and using a heartbeat.
Transmission and reception times are also monitored, allowing you to react to communications errors.
Discipline I/Os
Discipline I/Os are function blocks in the PX KNX system controller, which gather data from the RXB
controller and make it available on the BACnet network. Discipline I/Os are available for HVAC functions.
Konnex Association
The Konnex Association is an association founded by the manufacturers of KNX/EIB products, to define
interoperability guidelines for KNX/EIB systems. The association is responsible for checking compliance
and for the certification of KNX/EIB products.
KNX/EIB nodes
A KNX/EIB node is a device which is connected to the KNX/EIB bus and communicates with other
KNX/EIB nodes.
Network variables (NV)
Network variables (NV) allow the exchange of data between different KNX/EIB nodes. Network variables
may be input or output variables.
Room-based groups
The discipline I/Os representing the RXB controllers in a room are combined in the PX KNX system
controller into a room-based group. The result is a room view.
Cross-room groupings
Cross-room groupings contain all the control variables common to a given user grouping (e.g., north facade,
tenant A, west zone, etc.) and distribute these control variables to the associated room or group members.
PX KNX system controller
The PX KNX system controller comprises a PXC001(-E).D controller and loaded PX KNX firmware.
Communication takes place via BACnet/LonTalk (PXC001.D) or BACnet/IP (PXC001-E.D). With the system
controller, you can integrate the Synco RMU710, RMU720, RMU730 and RMH760 controllers into Desigo.
PX KNX Tool
The PX KNX tool is used to configure the PX KNX system controller on the KNX side.
