For the installation of the HD data store in ibaPDA select the same computer as the ibaHD-Server (localhost). The HD stores are also configured on the same computer. Every HD store can only store data from one source, i.e. a HD data store of an ibaPDA system. The number of HD data stores which may write to a ibaHD-Server simultaneously depends on the license. By means of the different HD data stores and the corresponding stores, you have the possibility to combine signals as required, e.g. production and maintenance data.
