The FACILITYMASTER is the EIBPORT's big brother. It incorporates all the functionalities of the EIBPORT, but is designed for use in large-scale projects. In addition, individual applications such as DATALOGGER, APPMODULE and KNXEASY are incorporated. Thanks to its option of accommodating connections to the EIBPORT or LINKMODULE, however, it is also ideally suited to property management. 256 simultaneous connections to all visualisations (except Java Control) are possible. CONTROL W even allows up to 2000 connections. The room allocation plan (CONTROLl R) enables as many as 256 rooms to be automated. More than 2000 jobs can be entered in one device. The DATALOGGER enables internal data recording of 50 million datasets. Some applications can be added without any difficulties using the integrated APPMODULE. They work in a separate virtual machine within the FACILITYMASTER so that they do not influence other processes. The integration of third-party software using the integrated KNXEASY is also possible. The pre-installed Logitech™ Media Server makes the FACILITYMASTER the control centre of all the music zones. Thanks to the new failure management, the FACILITYMASTER becomes a central alarm information system with logged user accesses. BAB SECURE LINK (specially-encoded facility coupling protocol) enables secure transfer to other BAB devices.
