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.

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 = L ocal for KNX access to the read only 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
Supply of the KNX communication board
Supply of the KSet software, the plug-in and the xml integration file
Installation of units equipped with KNX controller
Creation of the ETS database
Addressing and configuration of the KNX network
Definition of the links between KNX controllers and with the BMS
Definition of BMS setpoints and time schedules
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.

Push button
Meaning
No communication between KNX board and the
controller.
Communication error between KNX card and the
controller
Communication with the controller is established
The button has been pressed to allocate the address,
and the board is awaiting the corresponding procedure
from ETS
The board has not been loaded
Configuration in progress: ETS is loading the
configuration
Remote for KNX access to the read and write datapoints
Red Green
Cause / solution
Check the configuration:
- controller address incorrect
- transmission speed incorrect
- wrong protocol
The board has been configured with a version or
address not recognised by the controller BIOS.
Perform configuration from ETS.
Check: KNX bus power supply (29V DC), electrical
connections and polarity of connections on the
connector + and - terminals
