Enables data catch-up functionality of the communication.

• NoCatchup: No data catch-up, just pure real-time communication.
• SerializedFull: Historical data is streamed through Hive sample-by-sample, until we have caught up real-time. Note that this requires the UA server to implement the OPC UA HA profile!
• SerializedFull_PauseAfterInitial: Same as 'SerializedFull', but with one stop in playback sequence after first StepNext, use CommandItem #ContinueCatchup# to continue playback sequence.
• SerializedPartial: Only data missing locally, per item, is read from remote server and streamed through Hive, sample-by-sample, until we have caught up real-time.
• SerializedPartial_PauseAfterInitial: Same as 'SerializedPartial', but with one stop in playback sequence after first StepNext, use CommandItem #ContinueCatchup# to continue playback sequence.
• Direct: Data periods missing locally are read from the UA server and written directly to any configured Honeystore timeseries database for the item(s).

Note that to fully benefit from using catch-up, the UA server is required to implement the OPC UA HA profile!

More details on how to use catch-up can be found here.

How to generate item names on items from the UA NodeID, DisplayName and/or BrowseName. Set of predefined choices, or a custom string, containig following specifiers:

• {dn} = DisplayName
• {bn} = BrowseName
• {ni} = NodeId

Example: {bn}mystring{dn}

When to synchronize selected OpcUA Standard Properties from server nodes to local apis item attributes (EngineeringUnit, EURange, InstrumentRange).

• First time adding item
• Each session
• After replication

• Anonymous
• Username/password

If set to 'Username/password, the properties 'Username' and 'Password' must also be specified.

Use this property to specify which certificate the OpcUaBee should use when connecting to the server.

When property 'PkiType' is 'Win32', this property specifies the subject-name of a certificate in the Windows Certificate Store. Typically this will be the name of the ApisHive instance.

• Example using Win32: "ApisHive"

When property 'PkiType' is 'OpenSSL', this property specifies the name of a certificate file in the '<certificatestore>\trusted' folder.

• Example using OpenSSL: "ApisHive.der"

Persisted, File

(ReadOnly, Hidden)

This property specifies where the OpcUaBee should look for certificates. Default value is empty.

If PkiType is "Win32", this property specifies a folder within the Windows Certificate Store. If the property is empty, the OpcUaBee will use the value "UA Applications".

If PkiType is "OpenSSL", this property specifies a file system path relative to the ApisHive instance configuration folder. If the property is empty, the OpcUaBee will use the value "pki", which resolves to the folder "<APISDir>\Config&lt;InstanceName>\pki".

Persisted, Folder

(ReadOnly, Hidden)

This property sets the required security level for OpcUa messages. When setting this property, you may also have to set others.

If set to:

• Unsecure: You must set 'SecurityPolicy' to 'None'.
• 'Signed' or 'Signed and encrypted:' You must sprecify a 'SecurityPolicy' other than 'None'

This property specifies the timeout period for RPC messages sent to the OpcUa server, measured in milliseconds. Default is 5000.

This property selects which certificate handling implementation to use (PKI=Public Key Infrastructure). The options are:

• OpenSSL: using the filesystem to access certificates
• Win32: using the Windows Certificate Store.

Password used to authenticate with server. Only applies when the property 'Authentication' is 'Username/password'.

This propery is used to select the private key for the active certificate.

When PkiType is 'OpenSSL', the property specifies the name of a key-file in the "<certificatestore>\private" folder, encoded in PEM format. Typically, if CertificatePath is "ApisHive.der", PrivateKeyPath would be "ApisHive.pem".

When PkiType is 'Win32', this property is ignored (the Windows Certificate Store handles the link between certificates and their private key).

The time to wait before attempting to reconnect the server after an RPC failure, or time interval for watchdog evaluation if watchdog is configured.

This property is identical to the MessageSecurity property, but for the redundant server.
