TOP Server Release Notes (5.12.142.0) August 5, 2013

Server Utilities

• 
  Increased the maximum number of configurable endpoints to 100.
  
• 
  Display an error message in the Add/Edit Endpoint Definition dialog to prevent users from configuring more than the maximum number of endpoints.
  
  • 
    Note: A UA endpoint consists of a URL, security mode, and security policy. It is possible to configure more than one UA endpoint in the Add/Edit Endpoint Definition dialogs.
    

Server Utilities

• 
  The OPC UA Server now retains the user credentials that are passed by the client in order to activate a session. This identity is used to apply access control permissions that are defined in the User Manager.
  
  • 
    Note: Once an authenticated UA session is established, the UA Server can drop the connection if the user credentials associated with the active session are invalidated because the server user has been disabled. This functionality does not require the server to restart or reinitialize.
    

Plug-Ins

• 
  Resolved an issue where DataLogger could miss or duplicate data entries under certain conditions (such as when receiving a new item update from the server while still processing or logging a previous item update).
  
• 
  Added a Batch Identifier enhancement that allows users to select a tag as a “Batch Identifier” and then map it to a database column. When a database transaction is triggered, the current value of the Batch ID tag will be written to Batch ID column for all rows in the transaction.
  

• 
  Fixed a defect that would have prevented users from changing the name of a new CSV Exporter.
  

Drivers

• 
  Resolved an issue related to write performance where certain drivers with the ability to perform multiple writes per transaction were incorrectly performing single writes after an initial multi-write transaction. This change affects the following Ethernet drivers:
  
  • 
    BACnet IP
    
  • 
    Beckhoff TwinCAT
    
  • 
    Allen-Bradley ControlLogix Ethernet
    
  • 
    Custom Interface
    
  • 
    GE Ethernet (SRTP)
    
  • 
    Siemens TCP/IP Ethernet
    
  • 
    Simatic TI-505 Ethernet
    
  • 
    SNMP
    
  • 
    Triconex Ethernet
    
  • 
    WeatherBug
    
• 
  Changed the behavior with regard to how specific NIC adapters are handled. Prior to the 5.12 release, the server switched to the “Default” Network Adapter if the specific NIC adapter was disconnected or disabled. After the 5.12 release, the server will continue to use the specific NIC adapter initially selected. This change affects all Ethernet drivers as well as all serial drivers that support Ethernet Encapsulation.
  

• 
  Updated the driver to convert flow times reported by Totalflow devices in integer seconds to floating-point minutes. This makes flow times exported by the EFM Exporter for Totalflow meters consistent with other meter types.
  

• 
  Fixed a defect in which the “Synchronize with Controller after” settings were not being respected with regard to Online and Offline edits.
  
• 
  Changed a behavior where the driver will now retry tags instead of failing them upon detecting an Online or Offline edit (except for Downloads). It's likely that the next attempt will succeed. Also, Offline edits will take priority over Online edits if both occur before being detected by the driver.
  
• 
  Fixed an issue where the Protocol Mode drop-down selection arrow would not redraw correctly if the selection invoked a vertical scroll bar in the grid.
  

• 
  Initial release of this new Ethernet driver, which will be part of both the Allen-Bradley Suite and the Manufacturing Suite.
  

• 
  Initial release of this new serial driver, which will be part of both the Allen-Bradley Suite and the Manufacturing Suite.
  

• 
  Fixed an issue with g70v3 Open File requests, where the File Size and Time of Creation fields were not being initialized properly when the request was to open a file for writing on the slave.
  
• 
  Corrected an issue introduced through a fix in server version 5.10 in which events would continue to play back when a device was in an error state. Errors other than Device Not Responding (DNR) were not being considered. When event play back is enabled and the event poll times out while communicating, the .Value and .Timestamp tags will receive BAD quality (which was the previous behavior).
  
• 
  Fixed an issue introduced in server version 5.10 where integrity and/or event polls would not occur on schedule if channel serialization was in use with many .Explicit Tags.
  
• 
  Corrected an issue where an “Initialization Completed” message would be posted when no communications had occurred with the device.
  
• 
  Changed the Exchange Data Sets device property’s default setting from True to False.
  
• 
  Added support for legacy devices that use a local time zone adjusted with time reference instead of the UTC time base in events and during time synchronization.
  
• 
  Converted the Communications device property page to a grid control.
  
• 
  Fixed an issue where processing too many continuous internal/cache tags may have delayed the processing of device tags (especially when Channel Serialization was in use and devices were not communicating).
  
• 
  Fixed an issue where a non-empty Activate Configuration Object string incorrectly triggered automatic tag generation when other device properties were modified.
  
• 
  Fixed a rare issue where an erroneous file transfer failure message could be posted along with a file transfer completed successfully message when the file transfer was successful.
  
• 
  Corrected an issue where event play back paused during TCP connection attempts.
  
• 
  Corrected an issue where event play back paused while the device was demoted.
  

• 
  Fixed an issue with g70v3 Open File requests, where the File Size and Time of Creation fields were not being initialized properly when the request was to open a file for writing on the slave.

• 
  Fixed an issue where automatic tag generation would not create Point Types 101 through 109.
  
• 
  Fixed an issue where automatic tag generation created point types with incorrect Logical Addresses.
  
• 
  Added support for Point Types 98-x.53 through 98-x.60.
  
• 
  Added a Set/Clear indication to the beginning of the alarm strings exported via the EFM Exporter Plug-In.
  

• 
  Corrected an issue that occurred when reading symbolic variables with the PACSystems model, where symbolic array and array element tags might not be included in the same request.
  

• 
  The NIC card selected in Channel Properties is now respected by the driver. Prior to this fix, users could have encountered problems with device connectivity when selecting a non-default NIC card.
  
• 
  Updated the driver to disconnect and reconnect to devices when the NIC selection is changed while clients are connected to the server and requesting item updates from the device.
  
• 
  Resolved an issue that could occur when processing incoming data for multiple devices under a channel and result in communication deadlock.
  

• 
  Updated the driver to change the unsolicited communications timeout value from -1 to 0 (if applicable) when loading a project. This invalid value may be present in projects that were saved using older driver versions, and will invoke an error pop-up message after the Unsolicited tab is viewed in Device Properties.
  

• 
  Fixed faulty browsing logic where the driver would continue attempting to browse after an error was encountered. This could result in the driver being stuck in a loop while browsing.
  
• 
  Corrected a failure to import tags from servers that do not return the item name in the GetProperties response.
  
• 
  Fixed a defect where if the target XML-DA server returned OPC quality for an item, the driver would set the tag quality to Good during a subscription poll refresh.
  

• 
  Added support for BOOL arrays.
  

• 
  Added a check for the "EA" characters while parsing the response to the AT, AV, CM, CR, FP, and HM commands.
  

• 
  Fixed an issue where writes to multiple Alarm Setpoints could result in erroneous DNR messages being posted in the Event Log.
