Release Notes for Prosys Sentrol 3.2.0

Especially, the TPsStorageConnector has been revised strongly. If you have used it, do not hesitate to contact us for additional support in converting your projects.

Also note that the Tutorial Lesson 4 (Storage) has been updated.

The OPC client functionality has been tested at the OPC Interoperability Workshop - and passed among the first clients the tests against the new OPC Analyzer tool. In future it will be required to pass the Analyzer test in the IOP Workshop to get clients applications the Self-Tested status. The test results are visible at the OPC Foundation's Product Page

The major changes are listed below. There are also a lot of minor issues fixed and changed.

NOTE: Sentrol has also been verified to work with the new Turbo Delphi and Turbo C++ products!

New components

• TPsVariant

New objects/classes

New properties & methods

• TPsOPCServer.OnStateChange

• Published: TPsCustomStorage.VariablesTable, ModulesTable & VarPropsTable

• TPsStorageField.AddColumn/DropColumn
• TPsCustomStorage.AddColumn/DropColumn

• TPsHistorian.HistoryTable
• TPsStorageConnector.Table

• TPsBitset.StrictStates
• TPsBitset.Value: LongWord

• TPsVar.PropAsInt64 & TPsVar.PropAsLongWord to support this kind of values better

• TPsVar.Get/SetPropAsDataType also implemented for array variables

• (PsUtils.pas) IsUTF8String, IsLocalHost, LocalServerName, GetNetworkServers

Changed properties

• TPsStorageConnector no longer uses KeyFields. If you have used them, add the respective fields now to Links (without any Variable). Also, instead of calling Save with the key values, use SetSaveParamByName to set them prior to calling Save. And the same for Load (SetLoadParamByName).

• TPsStorageConnector.OnGetKeyValue is replaced by OnGetFieldValue.

• TPsStorageVarLink.DataType (used in TPsStorageConnector.Links) is now of TPsVarDataType (was TFieldType)

• TPsBitset.BitCount functionality has been revised

Changed procedures

• GetFileVersion in (PsUtils.pas) renamed to GetFileVersionStr

Changed forms

• TPsVarForm improved
• TPsOPCProviderForm made available to C++Builder

New features

• TPsOPCServer handles now much better remote connections - and calls OnDisconnect/OnConnect when it loses connections temporarily. It also notifies all groups of this and makes the OPCConnectors to undefine (set quality to bad) the variables respectively.

• The storage component now manages metadata tables in the database. See the tutorial Lesson4 for an updated introductory!

• OPCConnector Links editor CreateVariables Wizard has an 'automatic' option, which means that it will create correct variable components based on the link datatypes!

Fixed

• TPsOPCServer.ServerName was not configurable at design time for remote servers

• TPsByteArray changes are now reacted to in the OPCConnector, to make it possible also to write ByteArray data back to OPC servers

• TPsOPCConnector.OnCopyToExternal was never called

• TPsEventLog.Capacity was not used

• Include Sentrol installation directory to the system Path - Delphi cannot locate the packages reliably without it...

• Access violations still sometimes at OPC Provider applications closing down (especially with C++Builder!)

• Access Violations occurring occasionally at Delphi shutdown

• Sentrol is now included in the BDS 2005/2006 splash screen and about information

• a bucketful of smaller bugs were layed aside, terminated according to the standard procedure
