please help me sir for solve this problem.
We have inspected your log file a bit. As stated in the first comment, you should configure more PRAM. The last errors seen are caused by an out-of-pram condition during a download (configuration change).
But this doesn't seem to be the cause for the restarts. It seems the restarts are actually triggered manually (from CBF). Are you sure there is no one working on another project having a controller with the same IP address somewhere in your network? Maybe someone works on a copy of the project?
It would be possible to enable additional diagnostics on the controller to see which address connects to the controller and issues the command.
Another option would be to capture the network traffic to the controller e.g. using Wireshark.
Your problem looks like network related to me. Either the EI 813F is defect, or the cable from that Ethernet module to the switch, the switch itself or the cable from that switch to other stations is defect. But that is just a guess derived from looking at the diagnostics file. If you have another EI 813F on stock try that one and see whether the behaviour disappears. If you don't have another on stock, maybe you can exchange with the EI 813F from another AC 800F and see whether the problems moves with the card.
In general our PACT support would be the right channel for this problem.
