Summary0001451: Information missing in SeverCapabilities about maximum supported array length and string length
Description

Especially on embedded systems servers can only process a limited number of array elements. E.g. only 10 items per read.
If the client receives a TooManyOperations error it has no clue about what is the maximum.

1.) ServerCapabilities should contain MaxArrayLength and MaxStringLength variables wich reflect the configured values defined in the UaStack.

2.) The number if items in services may be even smaller than the MaxArrayLength.
E.g. I can read variables with an array length of 100, but I can only read 10 variables per Read call. IMO there should also be Variables like

  • MaxNodesPerRead
  • MaxNodesPerWrite
  • MaxNodesPerSubscription

How whould this work with aggregating servers?

Is this about Array Length of Variables or on service level or both?

Also maxNodesPerBrowse and check all services
(try to group similar services into one, e.g. fro subscriptions)

Add global MaxArrayLength and MaxStringLength and also define a proerty for individual data variables

Move operation limits to an grouping object called OperationLimits and make MaxArrayLength work with multidimensional arrays by multiplying the individual array length of each dimension.
