OPC UA Connection Failure with Siemens Sinumerik One

Ignition

Hello All,

I have Ignition 8.1 connected with Siemens Sinumerik One NCU1750.
I am using OPC Connections to fetch data from PLC.
My connection status is connected .
When there is new power cycle to PLC and Ignition PC the OPC communication shows as faulted.

To make connection healthy I have to enter passwords in Sinumerik Authentication page and Reboot again .
Then it comes up.
It should be automatically connected all the time.

Is there any settings for this.

Sounds like a Sinumerik question, not an Ignition question. Is there some procedure needed to save your authentication changes on the Sinumerik side to the Sinumerik's persistent memory?
