ST 3.4 - released 11th November 2005
-------------------------------------
Summary: HDA OPCServer performance enhancements, Preview Pane & OPC Interoperability Certification. Enhancements
------------
stPro
0523: A new View option called the "Preview Pane" has been added. This allows new data to be viewed
for plots that of sufficient duration for Compression to be in effect. This is achieved by
adding a user configurable 'pane' on the right hand side of the plot to show new data as it
arrives.
0521: Incremental updates to HDA OPCServers no longer request that the entire screen is redrawn.
This was implemented to reduce the regular load placed on the HDA Server by screen updates.
0506: Annotations can now be loaded from a file. An export option was also added to help the user
establish the required format for input files.
0503: Added 'Page Down' and 'Page Up' hot keys to toggle through any open Session Tabs.
stCollector
0101: No longer allow duplicate Annotations to be added to the Collector.
0100: Increased the size of Mem bytes and Mem blocks to reduce paging on plots showing durations greater
than two hours. The new values are 500 mapped blocks and 150 Mb Mapped bytes.
0098: The logic for handling AddItem failures has been revised to not turn an item offline for non specific
error codes of E-Fail. Items are now only being turned offline for specific errors, such as Invalid
Item ID and Unknown Item ID. InstallShield
0039: The Installshield is now signed. Bug fixes
---------
stPro
0530: Fixed a possible crash having loaded a plot file that referenced a Data Source that was not
in the Connect dialog drop down. When this occurred toggling the multiple connections drop down
resulted in the Data Source drop down becoming empty. Clicking OK to close the logon dialog would
then cause a crash.
0529: Addressed potential crash when exiting the Plot Properties dialog having selected a Compression mode
and moved to the View tab without having applied the Compression mode selection.
0526: Addressed potential crash when reloading a plot file for a plot that has previously failed to
connect to its Data Source.
0522: stPro now observes the maximum number of values that an HDA OPCServer wishes to return in a single
request.
0520: The default filter dialog was not setting the end time to current so newly added entries
were not showing the list of annotations.
0511: Annotations were being toggled on and off by "View All" and "View None". This is no longer the
case since the decision as to whether or not to display them is a User Preference and not a view
option.
0502: The filter time for the Annotation Browser was setting current time based on the clients PC. It
should have been using the earliest time of any of the Collectors that are being used as Data
Sources.
stManager
0143: Trailing white space on OPC item properties are now trimmed - OPC Interoperability issue.
0142: The resolution mode option on the Add Multiple Items dialog was being ignored.
0140: The logon dialog now uses LDAP to unwind nested Global Groups for domains running Active
Directory. ** Note, this item applies to all Sapphire Clients.
0139: The default name for a DL has been corrected to Node\Server.
0137: The stManager security tab Accounts drop down now works on NT 4.0.
0136: The Batch Delete dialog check box for hiding successfully deletes has been reworded as it used
to mention "successful imports". stCollector
0103: The Collector will now send replies in smaller chunks if the buffer space required to send the
message as a single request fails.
0102: Fixed Collector crash caused by B-flag Auditing for data requests without timestamps.
0099: Trailing white space on OPC item properties are now trimmed - OPC Interoperability issue.
stOCX
0032: Fixed a potential crash when disconnecting from a data source when stOCX and stTHOCX are both embedded
within the same container and are using the same data source.
0031: Addressed a timing related crash where stOCX and stTHOCX were not correctly synchronizing I/O when
embedded within the same container and were using the same data source.InstallShield
0038: Added the required LDAP Dlls for stManager item 0140.
