You can manually reinitialize I/O conversations for topics using the Operations Control Management Console. When you reinitialize a topic, the existing I/O conversation is closed and the entire process for setting up the I/O conversation restarts. All I/O points associated with that topic are affected when the reinitialization occurs. You can either reinitialize all of the topics or a single topic.
Note: You can also enable an automatic topic time out, in which the AVEVA Historian issues a disconnect and reconnect for a topic that has not provided data within a specified time span. For more information, see Edit general information for a topic.
