Abstract: A supervision system for supervising an object. The supervision system includes at least one agent unit. The object which is to be supervised is connected to at least one object access port of the agent unit. The agent unit is also connected to a superior supervisor unit by a network access port. The supervised object's operational information is received by the agent unit in a protocol specific to the object. The agent unit uses a converter to convert the object specific protocol into a protocol of the superior supervisor unit. The protocol converted operational information is communicated from the agent unit to the superior supervisor. The agent unit also includes a controller which opens a channel between the supervised object and a second supervisor in order to send the supervised object's operational information to the second supervisor including the object specific protocol.
