4.4 Selecting the device connections
Peripheral devices as well as room operating units and additional room sensors
must be activated (set to "Active") in the basic configuration before they can be
used in the application. As soon as a device is set to active, it can be connected
and further configured.
Activated KNX / PL-Link devices must be connected before powering the
controller, otherwise the device will not be recognized.
Modbus devices can be connected any time before power up or during run time.
Because of auto-connect and KNX power supply the number of room operator unit
and room sensors is limited, see "PL-Link [➙ 145]".
