In principle, the profile can be attached to any other object.
This configuration applies only to the QAX33.1 and QAX34.1 room units.
Configuration of the object ConfigLCD is only relevant in the case of the QAX34.1, as this is the only unit
with a display in °C or °F.
The configuration of the object EnableOperatingMode is only relevant in the case of the QAX33.1 or
QAX34.1, as only these two room units have the option of selecting Fan1, Fan2 or Fan3.
Where QAX units without an address switch are still in use, only one room unit per automation station can
be integrated. The room unit number in such cases is then "1".
LonWorks addressing
There are two ways to integrate data points from LonWorks devices:
● via Discipline I/O
● via standard inputs/outputs (the latter approach is only sensible with a small number of data points to
be integrated, e.g., from third-party devices)
Address syntax
The block registers the control variables and output variables of the RX devices (outside the CFC chart) in
accordance with the information in the [IOAddr] property (Input/output address).
Addressing starts with the prefix "L=".
Addressing via discipline I/O
L=DeviceType DeviceNo. GroupIndex(MappingTableNo.)
● DeviceType: M (Master), S (Slave)
● DeviceNo: Field device identification number
● GroupIndex: Group identification: Up to 4 similar groups of an application unit may exist in the field
device (e.g., lighting or window-blind groups). The group index number is optional.
● MappingTableNo: Number of the mapping table which is valid for that Discipline I/O.
More than one device can be specified for each [IOAddr] string. The devices are separated with a
semicolon. However, the maximum [IOAddr] string length of 60 characters must not be exceeded.
Addressing via standard I/O
L= DeviceType DeviceNo.GroupIndex(3RD[NVIndex.FieldIndex])
● DeviceType: M (Master). There are no slaves (S) with third-party devices There is only ever one device.
● DeviceNo: Field device identification number
● GroupIndex: Group identification: Up to 4 similar groups of an application unit may exist in the field
device (e.g., lighting or window-blind groups). The group index number is optional.
● ObjectType: Constant for third-party devices: 3RD.
● NVIndex: Network variable referenced in the third-party device.
● FieldIndex: Element number, if the network variable is structured
KNX addressing
You can integrate data points from KNX devices as follows:
● See
PX KNX, RXB integration - S-Mode (CM1Y9775)
● See
PX KNX, RXB/RXL integration - Individual addressing (CM1Y9776)
● Address Info LED for PX KNX: D=1001
19.7 Discipline I/Os
Discipline I/Os are standardized combinations of inputs and outputs related to a specific application. They
have a predefined number of parameters.
Three different input variable types can be interconnected to Discipline I/Os:
● Simple value
● Trigger value
● Commandable value
