Yes. Either the OPC server itself may report a timeout, but if it does not and still take too long, we make sure that the method returns anyway, after the configurable timeout.

In this case, however, the operation is not cancelled, so it may nor may not complete successfully - it happens after the method call has returned, so your code has no way of knowing.

The default timeouts are quite long: 1 minute.

Best regards

Timeout expired for WriteItemValue was created by SILI

If I call WriteItemValue and the timeout EasyDAClient.Timeouts.WriteItem has expired, the function will return, right? Is an OPCException thrown if the value wasn`t written successfully within timout period?

What are the defaults for EasyDAClient.Timeouts.WriteItem/ReadItem?
Should I increase these or other values to ensure that the values can be written or read successfully within timeout?

Thanks for help!
