Availability of Products
The success of an open network is determined by the availability of automation products that support the standard technology. CC-Link is supported by over 1400 association members who manufacture more than 1100 CC-Link compatible products (as of January, 2011). See the CC-Link Product Page for the Product listings.
Reliability
Reliability of a network involves immunity to electrical interference; the ability to identify errors, localize/isolate faults and allow unaffected devices to continue operating; and lastly the ability to recover from a fault condition and resume normal error-free operation without human intervention. At the physical layer, CC-Link employs the well known RS-485 signaling specification and expands on this by using three-conductor twisted shielded cable and high performance transceivers and line filters. Device conformance certification involves conducted, radiated and directly coupled electromagnetic noise. A device must be immune to this EMI and RFI to be certified. In the event that a device on the network stops communicating, CC-Link allows communication to continue with all other network devices. Upon correction of the fault, CC-Link automatically returns a disconnected device to full network operation. Another significant option to assure maximum reliability is the "Stand-by Network Master". This feature allows a Stand-by Master to automatically assume total control of network communications in the event that the Primary Master station ceases to function.
