Abstract
A controller system includes a controller, and a plurality of input/output control devices connected in series with the controller so as to allow communication therebetween. Each of the plurality of input/output control devices is configured to be connected with a sensor device. Each of the plurality of input/output control devices calculates a one-shot timer activation counter based on a total number of the sensor devices being objects to activate a one-shot timer out of the sensor devices that are connected with another input/output control device between a subject input/output control device and the controller.
Claims7
A controller system comprising:
- a controller;
- and
- a plurality of input/output control devices connected in series with the controller so as to allow communication therebetween, each of the plurality of input/output control devices being able to be connected with a sensor device, wherein
- each of the plurality of input/output control devices comprises:
- a one-shot timer that regularly increments or decrements a one-shot timer count;
- a one-shot timer interrupt generator that generates a one-shot timer interrupt based on the one-shot timer count and a one-shot timer activation counter;
- and
- an activation counter calculator that calculates the one-shot timer activation counter based on a total number of the sensor devices being objects to activate the one-shot timer out of the sensor devices that are connected with another input/output control device between a subject input/output control device and the controller.
