MonitoredItems filters

[dremsol]

When subscribing to a list of Nodes when using deadband_monitor a DataChangeFilter is tied to the subscription and used for each monitoreditem in the list. However, when having a different filter for the Nodes in the list how should we use this function?

According to the MonitoredItem model each time a MonitoredItem is sampled, the Server evaluates the sample using the filter defined for the MonitoredItem.

Something I fail to understand is when creating separate subscriptions for nodes with different DataChangeFilters, returning different subscription handles, are still visible under the same subscriptionid in my S71500.

Could someone clarify how this works?

You can create different monitored items with multiple calss deadband_monitor or subscribe_data_change or even _make_monitored_item_request.
I am not clear what you mean. So are you using multiple create_subscription or a you using on subscription with different Monitored items with differenent filters.
For each create_subscription a "SubscriptionId" is created. Each SubscriptionId can create multiple MonitoredItems, which all get a own "MonitoredItemId". Hope it helps.
