These instructions describe set-up and operation of two HomeServers (HS) or FacilityServers (FS) in redundant operation. The download include a global library with the required logic connections.Function:
In connection with a Gira KNX switching actuator, the active HomeServer switches itself off automatically after a time to be parameterised has elapsed. At the same time, a second (previously inactive) HomeServer switches on. Through cyclical monitoring in connection with a staircase function in the KNX switching actuator, left-out KNX telegrams or a defective HS can be detected and the redundant HomeServer started automatically.
Hard- und Softwareversionen: Gira HomeServer 3 and Gira HomeServer 4 from version 4.0
Gira Hardware: 1x 052900 KNX/EIB Gira HomeServer / FacilityServer
Bekannte Ausnahmen: Do you want changing the Gira HomeServer every day at 2 am, you need the following logic module in addition. Requirements: Redundant operation requires two of the same devices (HS-HS or FS-FS) on both of which the same firmware is installed. Installed and functional NTP server. Switching actuator with two available outputs and staircase function which can be activated for each output (e.g. KNX switching actuator, 2-gang, 16 A with manual operation, Gira Order No. 1040 00). KNX installation with system devices (power supply etc.). Only one device works at a time. The second device is switched off. Changes to the existing project are always programmed in the running device first and then in the redundant device. "Old" retentive files must be deleted from the FTP server manually. These files are created during each change to the project and are not deleted automatically. In the project settings of the Expert software, the two functions Read FTP and Write FTP under Network\Retentive memory are always to be parameterised. The date and time of the programming PC must be up-to-date. These two devices must be exchanged regularly. The time of these two devices must be identical. Deviations can result in data loss in the archives or with the occupied-home simulation.
