Applies To:
  • CitectSCADA 7.00
Summary:

HF700R140585 for CitectSCADA v7.00.

This hotfix provides a fix for:

Bug 36958 - Tags with and without cluster lead to incorrect point count in kernel.
Bug 40585 - TagSubscribe creates a new thread on every callback.

This hotfix introduces a Citect.INI parameter:

[Code]CallbackThreads
Range:   1 to 512
Default:  5

Purpose:  Control the number of subscription callbacks that will run concurrently.
Notes:     The upper bound of the parameter was chosen based on the upper limit of [Code]Threads, but setting it too high may result in exhausting the available Cicode threads, resulting in the error "Out of Cicode threads". 

Files Affected:
  • Client.dll                copy to CitectSCADA 7\Bin\Client.dll
  • CSAPSI.dll             copy to CitectSCADA 7\Bin\Client.dll
