PPS2 addressing
A PPS2 address is required when values are to be transmitted via the PPS2 interface. Addressing takes
place via the input/output address [IOAddr] and always starts with the prefix "Q=".
Address syntax
Up to five room units can be connected to one Desigo PX automation station and addressed via the PPS2
interface. The addressing syntax is as follows:
Q=RoomUnitNumber.Object(Profile)
Example: Q=1.40 (1)
The functions available in the room unit are mapped directly to the I/O blocks. The following elements of
the address are predefined:
Type (standard BACnet objects) Room unit
number
Object Object description Profile
1
Example
Analog input 1…5 24 Setpoint correction Q=1.24
Analog output 1…5 24 Setpoint correction Q=2.24
Analog input 1…5 40 Room temperature 0, 1…6 Q=1.40
1
Analog output 1…5 195 Room temperature display Q=5.195
Multistate input 1…5 205 Mode Q=4.205
Multistate output 1…5 205 Mode Q=2.205
Multistate output 1…5 206 Heating/Cooling display Q=3.206

The Profile relates to the configuration number shown in the next table.
The room unit is configured with this configuration number and appended to the Room temperature object.
Other objects are not assigned a configuration number. Only the relevant operating and process values are
mapped in the I/O blocks, rather than all objects of a room unit.
Six profiles have been defined to keep both the memory requirements and the demands placed upon the
user in practice to a reasonable level. If no profile information is supplied, the predefined device-specific
default value [DefVal] is used. As an exception in the case of the QAX units, Profile No. 5 is used.

This profile (or configuration number) is always valid for one room unit only. It is used to configure the
objects ConfigLCD and EnableOperatingMode and to define how the room unit is to operate (e.g., °C or
°F).
