Abstract
Abstract A control apparatus for controlling a controlled object including controlled elements comprises a host processor (1), a plurality of slave modules (19-22) and means (2, 3-10, 11-18) for the communication between the host processor and the slave modules. The host processor interprets a control program to generate commands for the controlled elements in response to demands sent from the slave modules. These commands are sent via the communication means to the respective slave modules. Each slave module is allotted to a controlled element and has a processor (24; 28; 32) which interprets and executes the commands for its allotted controlled element and generates a demand on finishing the execution of a command. This demand is sent via the communication means to the host processor and causes the next command to be generated.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
161 words
A control apparatus for the control of a controlled object including a plurality of controlled elements, which comprises a central controller, a plurality of local controller each allotted to one of said controlled elements and communication means connecting said central controller with said local controllers, and is characterized in: that said central controller is a host processor(l) supervising said whole apparatus and interpreting a control program to generate commands for the control of said controlled elements in response to respective demands from said local controllers, that each of said local controllers is a slave module(19;20;21;22) comprising a processor(24;28;32) interpreting and executing said commands for the control of said allotted controlled element to generate control signals and generating said demand causing said host processor to generate the next one of said commands on finishing the execution of each of said commands, and that said communication means(2,3-10,11-18) communicates information including said commands and said demands between said host processor and said slave modules.
Claim 2
Dependent Claim
161 words
A control apparatus for the control of a controlled object including a plurality of controlled elements, which comprises a central controller, a plurality of local controller each allotted to one of said controlled elements and communication means connecting said central controller with said local controllers, and is characterized in: that said central controller is a host processor(l) supervising said whole apparatus and interpreting a control program to generate commands for the control of said controlled elements in response to respective demands from said local controllers, that each of said local controllers is a slave module(19;20;21;22) comprising a processor(24;28;32) interpreting and executing said commands for the control of said allotted controlled element to generate control signals and generating said demand causing said host processor to generate the next one of said commands on finishing the execution of each of said commands, and that said communication means(2,3-10,11-18) communicates information including said commands and said demands between said host processor and said slave modules.
Claim 3
Dependent Claim
47 words
A control apparatus as claimed in claim 1 wherein said communication means comprises a plurality of memories(ll-18) each being accesible from'said host processor(l) and one of said slave modules(19-22) and interruption means(36-41) for permitting each of said slave modules to interrupt said host processor and vice versa.
Claim 4
Dependent Claim
28 words
