<p>The arrangement for signal generation for control rooms has means for indicating the state of an installation, by for example schematic displays and indicating lamps, and having data memories and means of access to the memories. Different parts of the installation contain substation (U1, U2) with intermediate memories (ZWS1, ZWS2) and transmitters (SU1, SU2) which code in numerical from the data on the respective parts of the installation, and add an indicating number to this data. In the central station (Z), memories (SP1, SP2) receive the data and indicating number, from which address information is gathered, via the output of memories (S11, S12, S21, S22). The memories are arranged so that a part of the data is delivered automatically, the remainder is only transmitted when a display signal is applied. Interconnection between central and substations and memories and means of indication is by means of two wire cable.</p> |
