6.4 - KNX
The use of KNX requires an optional board. The board is factory tted. If this is not the case, switch o󰀨 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 specic external power supply.

Red
Constantly lit No communication between KNX board and the controller.
Check the conguration:
- controller address incorrect
- transmission speed incorrect
- wrong protocol
Flashing Communication error between KNX card and the controller
The board has been congured with a version or address not
recognised by the controller BIOS.
Off 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
Rapidly ashing
The XML le has not been downloaded
A rapid ash indicates receipt of the address after the button has
been pressed.
Proceed with conguration.

Check: KNX bus power supply, electrical connections and
polarity of connections on the connector + 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, conguration, parameter setting or KNX network addressing service. The
conguration 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 conguration tools and their associated specications. 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 congured, 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 le X
Installation of units equipped with KNX controller X
Creation of the ETS database X
Addressing and conguration of the KNX network X
Denition of the links between KNX controllers and with the BMS X
Denition 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.
