Re: Republish values of monitored items
Hello,
A client can call the ResendData method at the Server object using the current SubscriptionId as input argument.
Note: The OPC UA specification describes the intended use of this method. It should only be called in a receonnect scenario where the client detects missing sequence numbers and is not getting them through Republish. Normally (i.e. without or only short network interruptions) a client will receive all DataChangeNotifications and there is no need to call ResendData.
The ResendData method is optional and not supported by all server products.
Best regards
