ABSTRACT
Many kinds of industrial network standards have been usFed for machinery safety while considering reduce wiring, monitoring the safety equipments and setting the safety devices easy in process automation or factory automation. However, open networks have been used in industrial field recently and recognized by the international standards of International Electrotechnical Commission or International Organization for Standardization. CC-Link has been approved as IEC 61158 and 61784 Standard for Fieldbus Networks for its high-speed field network able to simultaneously handle both control and information data [1-3] (MITSUBISHI 2009, IEC61158). With the high communication speed of 10 Mbps, CC-Link can achieve the maximum transmission distance of 100 meters and connect to 64 stations.
