A communication system for exchanging data between an actuator system and an external device, e.g. an operation where the communication system under the form of a gateway and a transcoder interprets the information in a bidirectional stream of data and distributes the information to both ends. The communication system is furthermore provided with a logger function, where the signals that are sent out to both sides of the gateway, are stored in a memory, so that the actions and signals that lead to an alteration on the actuator can later be reconstructed.
