With a redundant OPC-DA node licence, following an OPC server switchover, all the active alarms are being resent by Win911.
This should not occur, the standy OPC node should be synched with the active Node licence and should be able to see that thes are not new alarms and they don't need to be transmitted.
Also, there should be only one OPC source / alarm to configure when you have Hot backup node licence. THey only difference for the second source should be the OPC node source itself
