KNX is an optional feature, you need to order KNX module (hardware) and upgrade software license to use VFace in a KNX system. VFace connects KNX directly from bus no need for IP rotuter. KNX and Modbus RTU are using same ports so you must plug out Modbus RTU module (default installed) and plug KNX module to place shown below. You can connect up to 64 indoor units to KNX systems.
