AC 800PEC PP D513 crash
Last night a controller went down during production.
The visualization gets no more live data. The OPCDA connection to the controller is off. A Reconnect via the OPC Server Configuration (Smiley) fails. A download attempt from the Connectivity Server fails. "No Connection with 172.x.x.x".
But RNRP shows both paths as "up". For RNRP, the Network seems to be available. But the Engineer didn't try to ping.
After the reboot by switching off the power; the controller comes up again and a download from Connectivity Server works correctly.

All other 17 Controller were without any Problems. So it seems not do be a Server issue.
Did have anyone a similar issue?
