Abstract
A secondary device receives an instruction message accompanied by a counted value and compares the received counted value with a counted value stored in an internal memory. Thus, it is determined whether the currently received instruction message is the same as a previously received instruction message and an execution of a process based on the previous instruction message was completed. When the received instruction message is not the same, the secondary device transmits a response message after executing a process according to the received instruction message. In contrast, when the instruction message is the same, the secondary device transmits a response message based on a process history in the internal memory without executing the process according to the received instruction message.
