Abstract
A programmable controller according to one embodiment is included in a system including programmable controllers each having a storage and has an arithmetic processor and a transmitter. The arithmetic processor performs arithmetic processing for processing performed in the system. The transmitter controls transmission of log data to one of the programmable controllers of the system to store the log data in the storage of the one programmable controller having a lower arithmetic load on the arithmetic processor than that of the own programmable controller. The log data is associated with the arithmetic processing by the arithmetic processor.
Claims8
A programmable controller included in a system comprising a plurality of programmable controllers each having a storage, the programmable controller comprising:
- an arithmetic processor that performs arithmetic processing for processing performed in the system;
- and
- a transmitter that controls transmission of log data to one of the programmable controllers of the system to store the log data in the storage of the one of the programmable controllers, the one of the programmable controllers having a lower arithmetic load on the arithmetic processor than that of the own programmable controller, the log data associated with the arithmetic processing by the arithmetic processor.
A programmable controller included in a system comprising a plurality of programmable controllers each having a connection interface and an arithmetic processor, the connection interface connectable to an external storage, the programmable controller comprising:
- a receiver that controls reception of log data from one of the programmable controllers of the system, the one of the programmable controllers having a higher arithmetic load on the arithmetic processor than that of the own programmable controller, the log data associated with a an arithmetic processing by the arithmetic processor of the one of the programmable controllers;
- and
- a writer that writes the log data received by the receiver to the external storage of the own programmable controller.
An arithmetic processing system comprising a plurality of programmable controllers each having a connection interface and an arithmetic processor, the connection interface connectable to an external storage, wherein
- one of the programmable controllers, having a higher arithmetic load, includes:
- an arithmetic processor that performs arithmetic processing for processing performed in the system;
- and
- a transmitter that controls transmission of log data to another programmable controller to store the log data in the external storage of another programmable controller, another programmable controller having a lower arithmetic load on the arithmetic processor than that of the own programmable controller the log data associated with the arithmetic processing by the arithmetic processor, and
- one of the programmable controllers, having a lower arithmetic load, includes:
- a receiver that controls reception of log data from another programmable controller, another programmable controller having a higher arithmetic load on the arithmetic processor than that of the own programmable controller, the log data associated with an arithmetic processing by the arithmetic processor of another programmable controller;
- and
- a writer that writes the log data received by the receiver to the external storage of the own programmable controller.
