In this research, redundant mechanism for RTC-CANopen Manager is investigated to improve reliability of the system built with RTC-CANopen. In the RTC-CANopen system, it becomes impossible to monitor the CANopen devices when RTC-CANopen Manager is down. By solving the problem, the reliability of RTC-CANopen will be improved. And, it becomes a key to spread RT-Middleware. We tried doubling RTC-CANopen Manager as a solution for it. RTC-CANopen Manager is one of main RTC of RTC-CANopen, and has the function as the master node on the CANopen network. We achieved the reliability improvement of the system that used RTC-CANopen by this technique.
