Abstract:
1. Method for detecting a configuration of a plurality of lifting devices in a lifting system, wherein a plurality of lifting devices is selected for lifting a load and connected in series with each other by supply lines; wherein controls of the lifting devices in the lifting system are initialized by a control line; wherein a level is simulated and a first node address is generated and stored at the input of the control with a lifting device which is positioned at the open end of the series so that this lifting device is defined as the master lifting device with the node address wherein an output of the control of the first lifting device is subsequently switched and the level applies on an input of a subsequent lifting device, and a node address n+1 on the subsequent lifting device will be generated and stored; wherein the preceding step for the generation of the node address n+1 and enabling an output of the control will be repeatedly executed until another level is applied to the last lifting device intended in the series to signalize the end of the series, and a signal is provided to the first lifting device so that the node addresses assigned to the corresponding lifting devices will be stored.
