Abstract
When it is determined that a device ID request has been made by a master apparatus, a slave apparatus returns device ID information including the latest status information to the master apparatus, starts a status information collecting process for newly collecting status information after the return of the device ID information, measures whether or not a predetermined time has elapsed from a point of time after completion of the latest status information collecting process, and returns period elapse information showing whether or not the predetermined time has elapsed on the basis of a result of the measurement together with the device ID information.
Claims16
A method of obtaining status information showing a status of a peripheral apparatus by an information processing apparatus in a system including the information processing apparatus and the peripheral apparatus which are mutually connected by an interface, comprising the steps of:
- allowing the peripheral apparatus to discriminate whether or not a device ID request has been made by the information processing apparatus;
- when it is determined that the device ID request has been made, allowing the peripheral apparatus to return device ID information including the latest status information to the information processing apparatus and start a status information collecting process for newly collecting status information after the return of the device ID information;
- allowing the peripheral apparatus to measure whether or not a predetermined time has elapsed from a point of time after completion of the latest status information collecting process;
- and
- allowing the peripheral apparatus to return period elapse information showing whether or not the predetermined time has elapsed on the basis of a result of the measurement to the information processing apparatus together with the device ID information.
A control program which has been stored in a computer-readable medium and allows a computer to execute a method whereby an information processing apparatus obtains status information showing a status of a peripheral apparatus in a system including the information processing apparatus and the peripheral apparatus which are mutually connected by an interface, comprising the steps of:
- allowing the peripheral apparatus to discriminate whether or not a device ID request has been made by the information processing apparatus;
- when it is determined that the device ID request has been made, allowing the peripheral apparatus to return device ID information including the latest status information to the information processing apparatus and start a status information collecting process for newly collecting status information after the return of the device ID information;
- allowing the peripheral apparatus to measure whether or not a predetermined time has elapsed from a point of time after completion of the latest status information collecting process;
- and
- allowing the peripheral apparatus to return period elapse information showing whether or not the predetermined time has elapsed on the basis of a result of the measurement to the information processing apparatus together with the device ID information.
