Feature of CC-Link Complete RAS Function (Reliability, Availability, Serviceability)

CC-Link Network System SB 0080 SW 0080 ～ 0083 Easy Configuration Software Local Station Control by a master board for PC is available, too This is the slave station that enables N: N cyclic communication Master station Stand By Master station with Master and / or other Local and transient communication. (Local Station) Down Network Control Remote. Optical Device Station repeater（max. 7. 6 km) Input / Output (bit data) and numerical data (word data) can be exchanged by this station. Master Station for SI, GI fiber cable Joint（10 Mbps) This controls all slave. Rotary stations connected to CC-Link network. Local Station One master From station 3 rdisparty needed for a CC-link system. （ＣＣ－Ｌｉｎｋ） Remote I/O Station Many kinds of Repeater Only Input / Output (bit data) can. Wireless be handled by(Infrared this station. Partners Repeater(Tray) branch) Products Intelligent Device Station This station can perform data exchange, such as Input / Output (bit data) and numerical data (word data). full range of upavailable to 2. 5 Mbps、 And transient communication is also communication 0～ 100 m speed supported

Feature of CC-Link Communication method : Protocol (Broadcast-Polling) Master (1)' Slave 1 Slave 2 ………… Slave n Polling to slave 1 + Sending data (refresh data) to all slave stations Response (refresh data) from slave 1 (Receivable at all stations) (2) Polling to slave 2 (2)' Response (refresh data) from slave 2 (Receivable at all stations) (3) Polling to slave 3 (n)' Response (refresh data) from slave n (Receivable at all stations)

Feature of CC-Link Communication LSI (MFP) Since MFP (Mitsubishi Field network Processor) carries out communication process between master and slave stations, high speed and stable communication is realized.
