The AccessOPCUA Process Gateway now also supports external OPC UA information models. The following enhancements have been implemented for this purpose:

• Reload supports customized OPC UA information models without interrupting communication
• Mapping of customized OPC UA information models

Reload supports customized OPC UA information models without interrupting communication (S 250447)

If the Process Gateway uses a customized OPC UA information model, reloading is possible without interrupting the communication to OPC UA clients.

Reloading takes into account the following changes to a customized OPC UA information model:

• Customized node changes
• Mapping type changes
• Add, remove or change namespaces

Mapping of customized OPC UA information models (S 249638, S 249639)

The following methods are available for mapping variables of a customized OPC UA information model:

• Automatic mapping
  The AccessOPCUA Process Gateway automatically assigns nodes of a customized OPC UA information model based on the DisplayName property in the UANodeSet file to zenon projects and zenon variables, if corresponding variables exist in zenon.
• Mapping with Siemens SiOME software
  With this option, variable mapping is based on the manual mapping, which is saved in a file when using Siemens SiOME software. SiOME saves the mapping - as so-called extensions - in the UANodeSet file.
