A method for producing a connecting - redundancy for a serial communication system having a master unit and a plurality of slave units, which are interconnected as a series of point - to - point - compounds are connected in line topology, as well as corresponding serial communication system

摘要

For serial communication systems, which as a mono - master - system are designed in line topology, due to the invention, the tolerance with respect to any errors due to the use of an additional return line, in the form of a master. In the normal operation, this compound serves only for monitoring purposes. It is activated only in the case of a line interruption, in order to the communication to the "separated" subscribers, to take over. In this case, there are two independent lines between the master to the slaves.
