A METHOD FOR DETECTING AND REPORTING AN OPERATION ERROR IN AN IN-VITRO DIAGNOSTIC SYSTEM, A TRANSPORT DEVICE FOR A LABORATORY SAMPLE DISTRIBUTION SYSTEM, AND A LABORATORY SAMPLE DISTRIBUTION SYSTEM

摘要

The present disclosure refers to a method for operating a transport device in a laboratory sample distribution system, comprising: providing a transport device in a laboratory sample distribution system, the transport device having an arrangement of transport modules (2), wherein each transport module (2) is provided with a transport surface (6); a drive device (9) configured to move sample vessel carriers (5) on the transport surface (6); a module control device configured to control operation of the drive device (9); and a module network interface connected to the module control device and configured for data communication in a control network; a transport plane (4); and a controller device (13) connected to the control network through a controller network interface; and assigning a network address to each of the transport modules (2) in the control network; for each transport module (2), in the module control device storing its own network address and the network address of neighboring transport modules (8) located adjacent to the transport module in the arrangement of transport modules (2). A replacement operation is applied, comprising: receiving replacement information data indicative of replacement of an elected transport module (7) by a replacement transport module; transmitting a broadcast message through the control network to the module control device of the transport modules (2) including the replacement transport module, the broadcast message indicative of a start command; transmitting a network address request from the module control device of the replacement transport module to the module control device (10) of at least one of its neighboring transport modules (8); and ignoring the broadcast message by the module control device of the transport modules (2) of the arrangement excluding the replacement transport module. In the replacement transport module, the network address of the replacement transport module is received from the at least one neighboring transport module (8), and the network address of the replacement transport module is stored. The network address of the neighboring transport modules (8) located adjacent to the replacement transport module is stored. In the controller device a recovery message indicative of the replacement transport module being addressable by the network address for operation control is received. Further, a transport device and a laboratory sample distribution system are provided. (Fig. 1)
