Modbus TCP Communication Down

Dear ABB experts,

Please help me with next situation.

19-Feb-2018 at 4:13pm we lost one device which connected via modbus tcp.

We use ABB 800XA, PM861/TP830 and modul CI867.

You can see logs at attachment.

Cable from CI867 going to Cisco Ethernet switch and IT team are checking logs files.

Now i try to understand what equipment tripped.

Information is not enought, maybe you can guide me what i can check additionally.

Thank you very much!
