Modbus interface (building control system)

With the Modbus parameters in service mode, the RS 485 interface of the RLS 45 O and RLS 45 K controls can be reconfigured in a Modbus interface → Commissioning software.

If the RS 485 interface is configured as a Modbus interface, no further components (PPB 30 K, sensors, power units, room air controls etc.) can be connected at this interface.
