Abstract
Centralized registers in which commands can be written are provided in correspondence with a plurality of control modules. Centralized registers for managing the pre-emption status of control modules and their tree-configuration hierarchical relations are also provided in correspondence with a plurality of control modules. Control modules to which a command should be transmitted are specified by looking up the registers that manage the pre-emption status and the tree-configuration hierarchical relations. When control modules have been specified, the latched command is written to the registers in which commands can be written.
Claims4
A control system having:
- a plurality of control modules connected in tree-configuration hierarchical relations successively branching from top to bottom, and means for transmitting prescribed commands to these control modules;
- wherein:
- there is provided a command write register group having, in correspondence with the aforementioned control modules, a plurality of command write registers in which commands can be written;
- the aforementioned transmitting means has means for writing commands in the command write register group in accordance with the aforementioned tree-configuration hierarchical relations;
- and
- this writing means includes means for expressing the tree-configuration hierarchical relations by turning intersections of a switch matrix on or off prior to writing a command, and means for writing a prescribed command in the command write register group in accordance with signals instructing said writing, these signals having arrived via these intersections.
