Device Description
The KNX/EIB/TP1 module 753-646, a.k.a. KNX module, provides the integration
of two-wire TP1 networks or individual KNX devices into all relevant WAGO
building automation controllers.
The KNX module can be operated in the operating modes Device mode or
Router mode. In a KNX IP controller, the module can assume either the device or
router mode. When using a different WAGO controller, the module will operate in
device mode only.
If one or more KNX modules are operated in a KNX IP controller, it behaves as a
normal KNX device (device mode) within the TP1 network. This is also the case
when used with a different WAGO controller. The position, upstream or
downstream, of the KNX module is irrelevant.
The controller and the module are coupled via the local bus. The module also
features four termination points for the connection of the KNX bus line (two
KNX
+
in red and two
KNX –
in dark gray). As per EIBA/KNX Association, a standard
MSR conductor (e.g., PYCYM 2×2×0.8) or a telecommunications cable (e.g., J-
Y(St)Y 2×2×0.8) is recommended for the KNX bus line (red and black wires). The
bus line is installed in free topology (ring topologies may not be created). In
addition, the conductor length of the bus line is limited, and maximum conductor
lengths between bus devices may not be exceeded, therefore, general KNX
directives must be adhered to.
The I/O module has two programming buttons for parameterization in device
mode.
The engineering tool software (ETS) requests the actuation during activation of
the KNX module. And, together with the WAGO-specific ETS Plug-in, this
software is used for the activation and configuration of KNX devices.
Eight colored LED's on the modules’ enclosure signal active and inactive
operating modes, the data transfer via KNX and the local bus, the presence of a
KNX bus voltage, and internal states or fault conditions of the module (see
chapter “Display Elements“).
