More tests were performed, currently not explicitly listed here.
- ↑ do not know the HTTPS endpoint
- ↑ 2.0 2.1 getting BadIdentityTokenRejected from ActivateSession() with user identity = username/password
- ↑ the ServerDiagnostics.SessionDiagnosticsArray cannot be read with the credentials provided for testing
- ↑ server is revising publishing intervals to 0 and using its own
- ↑ 5.0 5.1 failed: reading and writing with IndexRange
- ↑ No dynamic nodes could have been tested.
- ↑ Empty ArrayDimensions instead of null returned with ValueRank=-2.
- ↑ DataChangeFilter=StatusValue does not prevent constant value with updating timestamps from being sent.
- ↑ 9.0 9.1 9.2 The SessionDiagnosticsArray node is missing, but the sessions are correctly available under SessionDiagnosticsSummary.
- ↑ Server sends data changes too fast.
- ↑ 11.0 11.1 11.2 Absolute Deadband filter: server sometimes sends notifications where the difference is less than the deadband
- ↑ HTTPS not supported by the server?
- ↑ Linux; driver-based
- ↑ reading Server_ServerDiagnostics_SessionsDiagnosticsSummary_SessionDiagnosticsArray (nsu=http://opcfoundation.org/UA/;i=3707) gives BadOutOfService
- ↑ reading ServerDiagnostics.SessionDiagnosticsArray gives BadNodeIdUnknown
- ↑ All nodes (even scalars from standard information model etc.) have ValueRank equal to -2 (Any): not compliant.
- ↑ The server returns ValuRank 0 for scalar nodes.
- ↑ GetEndpoints can return overloaded set of endpoints
- ↑ 19.0 19.1 Could not test much, server only has method calls support.
- ↑ 1) Effects of Writes with IndexRange are not sent through subscription. 2) Subscription ignores IndexRange. 3) After writing into an IndexRange, the whole array seems to be replaced when doing subsequent Read
- ↑ Sampling period 2000 ms, but receiving changes at around 1000 ms rate.
- ↑ Server sends changes too fast. I used sampling interval 2000 ms. The server has not revised it. But it has been sending notifications with average rate between 800-900 ms. I think it would be OK to send values faster than requested, but in that case the server should report the faster revised sampling rate properly to the client.
- ↑ Reading ArrayDimensions gives an array with zero elements. NodeID: ns=4;i=6013
- ↑ for S7-1500 family
- ↑ 25.0 25.1 no arrays available for testing
- ↑ sometimes getting just BadWaitingForInitialData and no further update
- ↑ Falcon appears to be a code name for upcoming version of dataFEED OPC Suite.
- ↑ Getting "Could not create SSL/TLS secure channel." with HTTPS endpoint; it is possible that the problem is on the client side.
- ↑ Writing with index range always gives BadIndexRangeInvalid
- ↑ Getting BadSecurityChecksFailed with attempts to make any secure connection.
- ↑ StructureDefinition-s do not contain fields of the base data type.
- ↑ There are nodes that have variable class, but return BadAttributeInvalid for the UserAccessLevel and Historizing attributes, which are mandatory.
- ↑ When the publishing rate was 1000 ms and sampling rate 2000 ms, the server provides changes every 1000 ms, which means it is sampling faster than requested.
- ↑ On subsequent connections after a network interruption, no initial update was sent for items that are static.
- ↑ values not changing
- ↑ 36.0 36.1 36.2 looks like LDS is not running
- ↑ based on Unified Automation C++ SDK
- ↑ Buggy NodeClassMask filtering in Browse service.
- ↑ Sample delivery approx. 50% slower than requested.
