To make this possible, the following conditions are predefined:

  Every device or subdevice is located within a zone

  Every data point (input or output) is assigned to a zone

  Every data point (input or output) has a precisely defined "Name"

Whenever an output and an input with the same "Name" are located in the same
zone, a connection is established automatically, as shown in the following diagram:

  For a detailed description of KNX (topology, bus supply, function and setting of

LTE zones, filter tables, etc.), refer to Basic Documentation "Communication via
the KNX bus for Synco 700, 900 and RXB/RXL" [6]

  LTE-Mode data points and settings are described in the Synco Application

Manual [12]

  To engineer and commission a specific system, use the Synco700 planning and
