To have an integrated device management for a hybrid elevator environment, at least one converter for converting device management messages according to a second protocol used by one or more peripheral devices to be according to a first protocol, which is used by the device management of the elevator environment, is added to the elevator environment. Further, the device management is configured to update, in response to receiving a device management message containing, as device information, at least an identifier of a peripheral device, network information to contain the device information in the device management message.

An elevator system has an electrical power cable that extends essentially inside an elevator shaft and is coupled to a power supply configured to output a voltage of a predetermined value. An elevator controller and a plurality of operating terminals are coupled to the electrical power cable. Each operating terminal is configured to receive electrical power from the power supply and to send and receive data signals via the electrical power cable in connection with an elevator call entered by a user at an operating terminal. The elevator controller is configured to send and receive data signals via the electrical power cable in connection with the elevator call.

According to an aspect, there is provided an elevator communication system. The system comprises an ethernet bus, at least one message forwarding element connected to the ethernet bus and being configured to communicate with a control entity that is external to the elevator system, and at least one elevator system component configured to communicate via the ethernet bus and being provided with an ethernet medium access control address. The at least one elevator system component is configured to at least one of receive an ethernet frame from the control entity and to send an ethernet frame to the control entity.

An interaction safety control between an elevator system and a machine passenger. An interaction safety control method between an elevator system and a machine passenger, which includes: receiving a command from the machine passenger; based on a received command, determining the safety of the command with respect to the elevator system; and in case that the command is determined to be unsafe with respect to the elevator system, not sending the command to an elevator control device of the elevator system.

A method and an arrangement for commissioning a passenger transportation system includes a mobile device that is computer-controlled from an application and which is configured to exchange data both with a programmable controller controlling the passenger transportation system and with an external database in which configuration information regarding configurations of a plurality of passenger transportation systems is stored. The method steps are: retrieving, from the external database by the computer-controlled mobile device, configuration information that details information regarding a configuration of the passenger transportation system; requesting, by the computer-controlled mobile device under consideration of the configuration information, commissioning information which details information regarding parameters that must be set within the scope of a commissioning of the passenger transportation system; and transmitting the commissioning information to the controller controlling the passenger transportation system. As a result, a commissioning process can be significantly simplified and is less susceptible to faults.

A call input device for an elevator system includes at least one call input facility having at least one directional call button, such as an up-direction call button and/or a down-direction call button. The call input device further includes a storage medium and an output region. During operation, when the directional call button is actuated, instructions for call input by a user stored in the storage medium are output in the output region.
