Hello !  
I use node-red-contrib-opcua event and client to see events and alarms. But I don't find how to retrieve alarms and events that are already fire when i start the opcua event... So I tried to use opcua method with typeCondition.ConditionRefresh : in the method, objectId is i=2782 and methodId is 3875, I also need an argument Uint32 with subscribe id in value. Where can I find this subscribe id ?

Or does exist another solution to retrieve alarms already fired ?

I hope my explanations of the problem are clear ...

Thanks for any help
