Distributed control system and distributed control method
First Claim
Patent Images
1. A controller for distributed control, comprising:
- a receiver for receiving a first command from a higher controller;
an outputter for outputting a control instruction to a lower controller; and
a processor, wherein an application program is incorporated so as to be executable by said processor and said processor obtains the control instruction on the basis of the first command or by use of the application program.

Abstract
A robot distributed control system includes a host controller issuing a first command and a plurality of communication controllers connected to the host controller in a tree-structured manner. The communication controller obtains a control parameter by interpreting the first command, or issues a second command by executing an application program in response to the first command and then obtains a control parameter. In either case, the control parameter is output from the communication controller to the motor controller by which a plurality of motors are controlled.

5. A distributed control system, comprising:
-
a first controller which incorporates a first processor and a first application program therein and issues a first command on the basis of the first application program according to information or an instruction from outside;
one or more second controller being connected to said first controller and incorporating a second processor and a second application program therein, said second controller obtaining a control parameter on the basis of the first command or by use of the second application program; and
a third controller being connected to said second controller for controlling a plurality of actuators on the basis of the control parameter. - View Dependent Claims (6, 7, 8, 9)

10. A control method of a distributed control system including a first controller incorporating a first processor and a first application program, a second controller being connected to said first controller and incorporating a second processor and a second application program, and a third controller being connected to said second controller and controlling a plurality of driving devices, including steps of:
-
(a) issuing a first command by said first controller on the basis of the first application program;
(b) obtaining a control parameter by said second controller on the basis of the first command or by use of the second application program; and
(c) driving the plurality of driving devices by said third controller on the basis of the control parameter. - View Dependent Claims (11)
