This property manages the size of the array of nodes passed by default in synchronous requests to an OPC UA server. Default value of this property is 0 (zero), which disables this management. This property's usage allows splitting a request into smaller requests, thus avoiding BadTooManyOperations-type errors. The OPC UA services affected by defining a value in this property are SyncReadAttributes, MapNodeIds, CreateMonitoredItems, and DeleteMonitoredItems.
NOTE |
The definition of a value for this property depends on the operational limits defined in the properties MaxNodesPerTranslateBrowsePathsToNodeIds, MaxMonitoredItemsPerCall, MaxNodesPerHistoryReadData, and MaxNodesPerRead of an OPC UA server. Please check the specific documentation of the OPC UA server for more information about these operational limits. |
