Features
The RMS "Pelikan" constitutes a complex of independent units (intended for measurement of different parameters) that are interconnected into common information network. The RMS network is built using Ethernet IEEE 802.3 technology, it accommodates measurement devices and workstations as clients. The network includes two servers (main and hot standby), or alternatively, it can have no server at all. The RMS allows performing all commutations necessary for repair or calibration of measurement units in hot mode, without interrupting normal network operation.
