The CC-Link system on a machine has been intermittently dropping out. Normally the Link Scan Time runs at a solid 87ms. When the system "drops out", the link scan time will increase. Sometimes double, triple, or go up 10x. It happens when the machine is running or when it sits idle. There are 33 stations on the network. The same stations do not always fault but sometimes all of the stations will fault at once (as seen in the attachment pictures.) We have changed the main QJ61BT11N, the processor, the Q62N power supply, the main backplane (base unit), all cards on the main backplane. Is it possible for one station or one of the cables to create a network wide problem? Any ideas thrown at us would be appreciated.
