Abstract
A transport system comprises a plurality of transport devices to be and a central control computer. The transport devices are coupled to a first communication path which is established autonomous and decentralized manner by communication devices. The central control computer establishes a second communication path in a transport network including the plurality of transport devices, and sets a correspondence between the first communication path and the second communication path to one of the plurality of transport devices. One of the plurality of transport devices transmits a coupling check request for checking coupling from the communication device to a loopback point to the central control computer. The central control computer transmits, depending on a result of the check of the coupling executed by the one of the plurality of transport devices, a coupling check response to one of the plurality of transport devices which has transmitted a coupling check request.
