1. A remote data processing system comprising:

  • a data receiver for receiving a data message;

    a remote software module arranged to receive the data message from the data receiver, the remote software module including at least a first stage software component cascaded with a second stage software component; and

    a fault detector associated with the first software stage component and the second software stage component to detect a fault in the remote software module by detecting whether the data message or a derivative thereof flows entirely through at least one of the first stage software component and the second stage software component, wherein the fault detector has logical connections including a connection with an input of the first software stage component, an output of the first software stage component, and an output of second software stage component and wherein the fault detector identifies the first software stage as a faulty software component if the data message is present at an input of the first software stage, but not the output of the first software stage.
