The described techniques address the issues of latency and lengthy processing times associated with conventional redundant sensor measurement systems that rely upon digital transmission protocols by implementing a diverse analog sensor interface architecture. The described architecture may advantageously use a number of sensor measurement paths that may be independent of one another or share any suitable number of common components to provide varying levels of redundancy. The analog interfaces may provide signal diversity with respect to the use of different types of analog transmission protocols, which may include different signaling interfaces (e.g. differential versus single-ended), different transmission interfaces (e.g. voltage versus current interfaces), and/or the use of different signalization schemes.

It is provided to implement a different number of logical slaves in a field device for use in an AS interface network as a function of the assigned address, which slaves may be addressed using the assigned address in the standard or in the expanded addressing mode. Thus, in a field device, it is possible to provide slaves having different profiles, via which different data types may be exchanged. Furthermore, a method is provided, with which a field device having different slaves is able to be addressed in a simple manner while avoiding double addressing.

Method for monitoring an apparatus connected to a communication channel wherein the method is connected to a communication channel in a vehicle. When an interval of time between two messages that are output by the apparatus is shorter than or the same as a determined period, the method determines is the apparatus is in a correct state. The apparatus can output a monitoring sign-out message to the communication channel. When a message recently output by the apparatus includes the monitoring sign-out message, it is determined that the apparatus is in a correct state.

The present invention aims to reduce an operation burden related to the change of reception processing in a master device when a device connected to a slave device is changed. A device communication managing unit (10) transmits the data received by a device (20) communicating with a device communication port (110) in a first mode to a field network (50) by using a data format used for transmitting the data received by the device (20) communicating in a second mode.

Provided is a network that is constituted in a train formation; communication relay devices; terminal devices; and a position-information distribution device.
