METHOD FOR REPLACING A SIGNAL BOX, CONNECTED TO AN ELECTRONIC SIGNAL BOX, HAVING A RELAY INTERFACE INPUT/OUTPUT, WITH A FURTHER ELECTRONIC SIGNAL BOX HAVING AT LEAST ONE DATABUS INPUT/OUTPUT, AND ELECTRONIC SIGNAL BOX

摘要

In order to be able to replace a first signal box, connected to an electronic second signal box, in relay engineering with a further electronic third signal box in a time- saving fashion, the electronic second signal box used is an electronic second signal box having such generic functionality for its inputs/outputs that setting up a databus connection between the databus input/output of the further electronic third signal box and a databus input/output of the electronic second signal box involves a databus input/output of the electronic second signal box being activated and the relay interface input/output thereof being deactivated. An interruption of the databus connection involves the databus input/output of the electronic second signal box being deactivated and the relay interface input/output thereof being activated.
