In the drawing, central control devices ZSi, ZSl are shown that from the replacement switching devices ESEa to the part LSIöJ / of the line and ES currently being used Eb corresponding switching command line systems LS I the equivalent switching devices ESEa, tib go out: these switching command lines via ESEb information about the discharges to be output, which, however, is not shown in detail in the drawing for reasons or connection commands, ie about the replacement switching commands to be output for the sake of clarity: If, for example, an error has occurred to the connector inputs of the individual 15 line system parts LSI ast , then the square-framed switch.

If, starting or one and / or other key of the just considered example of a und'oder in the SteuereinrichtungZSl ZS2 forth by a between the decentralized control units and the corresponding Alarmsi The alarm signal line (IaLB), which is connected to the alarm signal line (IaLB), the replacement switching system part LS I ast reported the error that occurs to the above-mentioned devices ESEa, ESEb , which afflicts the alarm line system part with such an error, signal and, if necessary, further error information. that also the mentioned exchange of information between their type, especially their origin. see the substitute switching devices and the zenevaluation. If the replacement switching devices 55 have impaired central control devices, then ESEa, ESEb the alarm signals and error information supplied to them in the replacement switching devices ESEa, ESEb in the event of such a fault are indicated by corresponding alarm signals. In response to a recorded and to a certain extent processed, such occurrence of faulty information passes under the alarm signals indicating the exchange of information shown in the drawing, the conditions are given by the equivalent switching device connected to the line Go on the output side, for example the system LSI connected replacement switching device, i.e. the replacement switching device ESEa, directly, ESEa Information relating to the error, ie without related information from the control devices ZS1, ZS2 to be located between the control units ASt and the central control devices ZS2, a command to switch off the relevant part LS1 ast of the line system currently being used , for example, the line system LSI to the central control devices systems LVI, and connecting the other Leitunes-ZSI, ZS2, the central control devices ent systems (L?

If, in deviation from the example described above, an error does not occur in a line system part LS I cw / or LSHast running between the decentralized control units (ASi) and the central control devices ZSi, ZSl or in one of the decentralized control units (ASt) itself or from these controlled devices, such.

For example, if a fault occurs in the line system part LS I sp, commands for switching off the line system LSI and connecting the line system LSII to the outputs of the associated central control device and to the inputs of central control devices and for the corresponding switching of the Memory Sp ', Sp ", decentralized control units ASt and substitute switching devices ESEa, ESEb are delivered to the switches in question, which are provided with a rectangular frame in the drawing on the output side »n a line system currently connected to the central control devices, for example the line system £ .51, is connected, the equivalent switching device immediately sends equivalent switching commands to shut down this line system LS I from the outputs of the relevant Memory 5p 'and switching on to the outputs of the other memory 5p "to the switches sp'I and sp" \\ which are suitable for this equivalent circuit. If an error occurs in a central control device, for example the central control device Z52, a command to switch off the relevant central control device (ZS T) is issued immediately from the relevant replacement switching device, namely under the conditions shown in the drawing the switches I «.v / Z, Ztistl, l.vpZ and Zvp2.
