5.4 - KNX
The use of KNX requires an optional board. The board is factory fitted. If this is not the case, switch off the controller and insert the
board in J13 (entitled BMS card or BMS1) on the controller.
The bus used is a TP1, with a transmission speed of 9600 Bds. This bus requires a specific external power supply.

Meaning
Cause / solution
Red
Constantly lit
No communication between KNX board and the
controller.
Check the configuration:
-
controller address incorrect
-
transmission speed incorrect
-
wrong protocol
Flashing
Communication error between KNX card and the
controller
The board has been configured with a version or
address not recognised by the controller BIOS.
Off
Communication with the controller is established
Green
Constantly lit
The button has been pressed to allocate the address,
and the board is awaiting the corresponding procedure
from ETS
Rapidly flashing
The board has not been loaded
Perform configuration from ETS.
Slow flashing
Configuration in progress: ETS is loading the
configuration
Green + Red
Both constantly lit No power supply on KNX bus
Check: KNX bus power supply (29V DC), electrical
connections and polarity of connections on the
con and - terminals
To validate the KNX communication protocol on the PLC, adjust the following values in the "Communication" menu on the user terminal:
-
P700 = Protocol = KNX
-
P716 = Control type = Local for KNX access to the read only datapoints
Remote for KNX access to the read and write datapoints
The manufacturer does not provide a system start-up, configuration, parameter setting or KNX network addressing service.
The configuration of this type of network requires the creation of an ETS database. This database may only be used and managed by
personnel trained and expert in the use of KNX configuration tools and their associated specifications. Refer to the recommendations
issued by the KNX association (www.knx.org) for more information on this matter.
To ensure the KNX network is correctly configured, each party must undertake to adhere to the following roles.
Task
Brand
Integrator
Installer
Supply of the KNX communication board
X
Supply of the KSet software, the plug-in and the xml integration file
X
Installation of units equipped with KNX controller
X
Creation of the ETS database
X
Addressing and configuration of the KNX network
X
Definition of the links between KNX controllers and with the BMS
X
Definition of BMS setpoints and time schedules
X
Considering the central role of the integrator, it is essential that the latter is included in the project as early as possible so as to be able
to anticipate and validate the BMS architectures, integration tools, etc.
