Can anyone shed some light on this situation for me? I went to a sister plant yesterday to add alarm loggin to our network on from a HMI. At one point the HMI locked up so I needed to reboot it. When I rebooted the HMI the entire line went down. This was a major ordeal that took an hour and a half to recover from.
At the plant I typically work out of we can reboot the HMI's with out a problem.
On the HMIs that reboot without issues the connection in WinCC Flex is as follows:
Name - CPU319
Active - ON
Communication Driver - Simatic S7 300/400
Station -
Partner -
Node -
Online - On
Interface - Ethernet
On the HMI that crashes the line on reboot the connection in WinCC Flex is as follows:
Name - CPU317
Active - ON
Communication Driver - Simatic S7 300/400
Station - \Machine\Simatic 300(1)
Partner - CPU 317-2 PN/DP
Node - PN-IO
Online - On
Interface - HMI IE
The big difference is that the machine that crashes has a station, partner, and node selected. This automaticlly changes the interface from Ethernet to HMI IE.
I checked the OB's and didn't see anything for this situation.
I have been told the machine crashes also if any of the 3 cognex cameras are rebooted.
Is this a profinet issue? I figured there would be and OB86 or something to keep the line from going down.
Sorry this was so long,

Edit:
Also the HMI is a MP377
