You can hook to the EasyUAClient.ServerConditionChanged event.

Still, try to look at it from higher perspective. "I want to show the current status of the connection" is not an answer to "What you want to achieve?", unless you are developing a diagnostics tool. So, what is it that you are trying to achieve?

Hello.
What do you want to achieve?

If you repeat the Read after some time, QuickOPC will reconnect. The time between the failure and reconnection is configurable. No need to extra coding.
