OPCUA32 crash C0000005 and 0xc0000374 reading UaCPPServer VariableWithByteStringNodeId

OPCUA32 crash C0000005 and 0xc0000374 reading UaCPPServer VariableWithByteStringNodeId

Description

OPCUA32 driver crashes when reading UACCP server variables with byte string node ID. You receive error messages with reference to C0000005 ACCESS_VIOLATION or STATUS_HEAP_CORRUPTION.

 

This error has been fixed.

 

To benefit from this fix:

  • Update your zenon Software Platform to the latest build of zenon 11 or higher.

 

Note: You may encounter problems when using opaque node IDs. Opaque IDs are stored without ID encoding. If these IDs contain special values, such as 0, they will not work. This behavior is necessary for compatibility reasons.
