Canopen over EtherCAT(CoE) is a Canopen protocol that operates based on EtherCAT in industrial sites. In order to analyze a CoE network system and a performance through packet sniffing and reversing, it is necessary to know Data Objects structure and changes of its value. However, since Data Objects in Canopen is dependent on the devices, there is a limitation by using an existing packet analysis program like a Wireshark. Therefore, we designed and developed a system that infers Data Objects structure and system configuration.
