Configuration process
The first step of the configuration is performed OFFline (i.e. disconnected from the network). It consists of defining, within ETS, the
list of products used in the project and of defining the group addresses (i.e. the data which will be exchanged between the
KNX controllers). To do so, the manufacturer supplies a knxproj file (ETS compatible from version 5.6) describing the
KNX communication table for the delivered controller. This file contains a preconfigured PLC model, which can be duplicated as many
times as there are controllers on the bus.
The air handling unit program uses the KNX Datapoint types below:
Name type Standard ID Format KNX range
Boolean
(DPT_Switch)
1.xxx 1 bit Off / On
Unsigned 8 bit
(DPT_Value_1_Ucount)
5.xxx Unsigned 8 bits 0 to 255
Unsigned 16 bits
(DPT_Value_2_Ucount)
7.xxx Unsigned 16 bits 0 to 65535
Floating 16 bits
(DPT_KNX_Float)
9.xxx Floating 16 bits -671 088.64 to +670 760.96
32-bit signed
(DPT_Value_4_Count)
13.xxx 32-bit signed -2 147 483 648 to +2 147 483 647
The air handling unit PLC comes as standard in the knxproj file with 2 tabs:
-
The Group objects tab is used to select and address the desired KNX datapoints
-
The Parameter tab is used to adjust the variables emission frequencies in order to optimise the bus bandwidth. The others
parameters have been preset, and must not be modified.
None of the machine configuration parameters are available in KNX, they are only accessible from the air handling unit's
HMI terminal.
