PROBLEM TO BE SOLVED: To analyze how the system has been affected from a surrounding environment when there is any defect in the communication. SOLUTION: A transmitter 3 is composed of a transmitter side clock means 7 measuring a transmission time and a transmitter side recording means 8. Since the transmitter side recording means 8 records the transmission time and the transmission content, when a 1st device 1 is defective, whether or not the transmitter 3 has made normal transmission is analyzed. Furthermore, a receiver 9 is composed of a receiver side clock means 14 measuring a reception time and a receiver side recording means 15. Since the receiver side recording means 15 records the reception time and the reception content, when a 2nd device 10 is defective, whether or not the receiver 9 has made normal reception is analyzed. |
