  • Patent number: 6792603
    Abstract: In a distributed processing system including a plurality of programs distributed in a plurality of processing units and in which a program on reception side performs processing using a message transmitted from a program on transmission side, a management table for managing start of programs on reception side is provided in a processing unit in which the program on reception side is provided. A program utilizing the message transmitted from the transmission side is recognized and the recognized program is started at the start timing indicated in the management table. The start timing of the program set in the management table may be registered previously or the message may include information indicating the start timing.

  • Patent number: 6665717
    Abstract: In a distributed processing system including a plurality of intelligent devices such as an optical sensor and a processing machine connected via a network to each other, when a first optical sensor is moved from a first section to a second section, if an identifier indicative of the second section is set, then the first optical sensor transmits a retrieve message containing this identifier via the network so as to seek a second optical sensor which is set to the same second section. Then, the first optical sensor acquires a setting parameter from the second optical sensor, and executes an operation in cooperation with the second optical sensor set in the same second section. As a result, in such a distributed processing system including a plurality of computers (intelligent devices) whose processing contents are different from each other, depending upon setting places thereof, workloads for changing the setting values of these computers can be reduced.
