Abstract
Abstract A processing unit is provided in the form of a status and control unit which co-operates with a central station via a communications link. The unit is controlled by a microprocessor which is programmed to operate in a functional configuration controlled by the settings of one or more parameters. These parameters may be changed by means of a message transmitted to the unit from the central station.
