ABSTRACT:
This invention relates to a supervisory control and data acquisition (SCADA) system in which a central station (10) sends control information to, and acquires information from remote stations (11, 12) over a wire, radio or other link. Each station comprises a tabular memory (15-18) comprising storage locations in an `x` direction for storing data relating to different elements of the second system and storage locations in a `y` direction for storing data relating to different parameters of those elements. Transmitting means are provided for transmitting a message from one unit to the other unit, said message comprising an `x` part, a `y` part and a qualifier, for reading from and writing to storage locations in the tabular memory of the other unit depending on the result of a logical operation defined by the qualifier. The tabular memory can equally be considered to have a tree-like structure.
