Abstract: According to an aspect, there is provided a method for determining a sequence of bus nodes in a multi-drop communication bus. The method includes for each bus node: sending a request to the bus node using an bus node physical identifier to set the bus node to a loopback mode; transmitting at least one signal to the bus node via the multi-drop communication bus; receiving from the bus node a loopback signal caused by the at least one signal; and measuring a roundtrip delay between the at least one signal and the loopback response signal. The method further includes solving the physical order of the bus nodes in the multi-drop communication bus based on the roundtrip delays.

Abstract: An elevator communication system includes a first elevator controller; a second elevator controller; and a first ethernet bus portion connected to the first elevator controller, the first ethernet bus portion having sequential bus segments interconnected by at least one switch. The first ethernet bus portion is arranged in a first elevator shaft. A second ethernet bus portion is connected to the second elevator controller and includes sequential bus segments interconnected by at least one switch. The second ethernet bus portion is arranged in a second elevator shaft. A switch of the first ethernet bus portion and a switch of the second ethernet bus portion are interconnected to enable data transmission between the switch of the first ethernet bus portion and the switch of the second ethernet bus portion. The first elevator controller is communicatively connected to the second elevator controller.

Abstract: An elevator communication system includes at least one ethernet bus segment, a controller communicatively connected to the at least one ethernet bus segment, and a plurality of elevator system nodes communicatively connected to the at least one ethernet bus segment. The controller is configured to determine a fault situation in the elevator communication system and cause reduction of the data communication via the at least one ethernet bus segment based on the fault situation.

Abstract: According to an aspect, there is provided an elevator communication system. The system comprises an ethernet bus, a safety master node communicatively connected to the ethernet bus and configured to communicate via the ethernet bus, and safety slave nodes communicatively connected to the ethernet bus and configured to communicate via the ethernet bus. The safety master node and the safety slave nodes are configured to communicate by using a time-triggered communication protocol. In the time-triggered communication protocol the safety master node is configured to send a polling diagnostic request message to the safety slave nodes by using a predetermined polling cycle.
