The DAKON is a front-end fault-monitoring computer with up to 24 interfaces for connecting OSCILLOSTORE P531 fault monitoring systems and up to 32 interfaces for connecting numerical protective relays with VDEW6 protocol, IEC 870-5-103.

The unit is used for archiving and transmitting the data of the connected end units. The analog signals of a fault recorded by a OSCILLOSTORE P531 or the numerical protective relays and the operating signals of the units are saved in a data base on the hard disk drive. Depending on the user configuration, they are printed, displayed on a optional screen and/or transmitted to a connected evaluation facility. If required, the system program "Diagnosis of faults in the power system" evaluates the faults automatically and represents or forwards them in plain text, if appropriate with the fault location, and/or as rms curves.

The connection between the OSCILLOSTORE P531 fault recorders and the DAKON is realized either with V.24, TTY (current-loop), or optical fiber. The corresponding assembly of the interface modules is listed in the ordering data. With a V.24 interface and the respective dial-up modems, the user can configure the OSCILLOSTORE P531 systems connected to DAKON interfaces via the telephone network.

Data transmission to the remote evaluation computers can be made via two interfaces, according to user configuration. Like with the OSCILLOSTORE P531, the data can be transmitted via dedicated line, the public telephone network or X.25. In addition, the connection can be realized with ISDN, a LAN, or a WAN.
