PI Interface for OPC DA 2​.7​.2

41277

Updated default authentication level to 'Packet Integrity' in order to be compatible with the requirements of Windows DCOM Server Security.

Notes:

Interface: The DCOM security authentication level is defined by the /da parameter.

OPC servers: The PI OPC Servers will continue to work using that setting. It is recommended to use that setting in the DCOM hardening guidelines. By default, the PI OPC Servers will use an authentication level of 'Default', which will use the machine-wide setting defined at the Computer level. If the machine-wide authentication level is set to Packet Integrity or greater, no change is required.

Third-Party Applications: Some OPC applications will fail to establish communication even though the system-wide authentication level is set to Packet Integrity because they hard-code the authentication level to None, Connect, Call, or Packet. Contact the specific vendor of the application for details on how to enable an authentication level of Packet Integrity or greater.

Performance: Application performance could be impacted. It is recommended to test with Packet Integrity to ensure performance remains adequate in your environment.

To mitigate performance issues, the following should be considered:

• use advise tags instead of polled tags

• assess data density requirements and adjust scan classes

• split tags into multiple interface instances/OPC servers

• install the interface on the OPC server machine

• upgrade old hardware

43132

Updated dependencies included in install kit provided by OPC Foundation to latest version.

72453

Removed bundled executable tools for security purposes including:

• APIOnline.exe

• DaVinciBackUpExe.exe

• makedumpset.exe

• opcrefresh.exe

• opcresponse.exe

• opcscan.exe 

  In the rare case one of these tools are needed, they can still be obtained from the last previously released version of the interface.

40582

ICU Control now correctly adds /UWQ parameter to the .bat file even if is set to the default value of 0.

40584

Interface now sends "good quality" when /SG is parameter is set.

40593

Resolved duplicate data in PI DA resulting from duplicate connections to the OPC Server when interface gets disconnected from the OPC Server.

40602

Exceptions occurring in the On data changed are now caught and logged.

40608

Resolved incorrect file permissions on .cred file creation. The service user now has access to the credential file.

40619

Backup interface will only collect data from the OPC Server during hot failover. When the interface is assigned to "primary," it will begin sending data to PI.

40623

Interface now continues to update existing Advise tags according to their ExcMax parameter when a new Advise tag is added to a separate empty scan class.

40633

Timestamp plug-in now works with event (triggered) PI points.

40636

Startup Delay (/SD) can now be greater than 2 seconds when connecting to a DeltaV OPC Server.

40641

Resolved interface not sending correct values for VT_DATE types when using a certain time format (/TF) parameter. Both 'ccyy' and 'yy' are now properly parsed when sending outputs.

40651

Resolved interface incorrectly reporting opc quality 0xFF as a "Bad" quality when quality should be reported as "Good." Interface now accepts quality range 0xC0 - 0xFF as a "Good" range.

40652

Resolved the interface stopping unexpectedly when adding data to queue.

40668

Resolved interface stopping unexpectedly from misconfigured location codes. Interface now reports an error message with invalid scan classes and then exits.

40670

Interface now starts, collects data, and utilizes specified digital states when Generic Plug-in DLL is used.

40672

When the /CredFilePath is left empty, the warning message now displays the correct parameter name.

40675

Resolved the PI OPC DA Interface falsely reporting the device status "One or more groups not getting data" under certain configurations

40676

Resolved PI String tag output event not being correct if day part of date is not specified in time format (/TF).

40705

OPC DA Server VT_DATE tags with millisecond timestamp values are now written to PI string tags (location2=7) with the correct millisecond values as per the time format specified on the interface, and as decimal second values written to PI Float tags.

43675

Resolved explicit logging for output tags assigned to an output group that does not exist.

72454

Generic and Metso plugins now read digital states properly.
