Abstract

A clock value converter in a CPU replaces a value of a carry counter in a safety clock in the CPU to cause the carry counter to show dispersed values. The CPU transmits a frame including a value of a time stamp and a first error detecting code generated based on the value of the time stamp and the value of the carry counter to a CPU. A clock value converter in the CPU causes, as in the CPU, a carry counter in a safety clock in the CPU to show dispersed values. An error detector in the CPU determines whether a second error detecting code generated based on the value of the received time stamp and a value of the carry counter in the safety clock in the CPU satisfies a condition set for the first error detecting code.
