COMMUNICATION SYSTEM ABSTRACT A communication system is disclosed for a distributed control arrangement comprising a plurality of communication nodes, each corresponding to a separate physically remote operating unit of a common installation. Each node includes a set of port buffers respectively associated with separate subsystems of the corresponding operating unit, a common node bus and a controller. Each port buffer is adapted to establish a 2-stage transfer link between its corresponding subsystem and the controller, in which the port buffer provides intermediate data storage. One port buffer of each node is coupled to a secondary station associated with that node which is slaved to a primary station. The primary station issues commands through a common data link to the secondary stations and communicates with selected subsystems associated with each node through the secondary station corresponding to that node.
