CitectSCADA does not automatically get locked to run on a single processor in multi-processor systems.

In CitectSCADA 6.00 service pack A an INI file parameter [General]LockToProcessor has been added. This parameter defaults to 1 (the first processor).

This parameter sets the processor on which CitectSCADA will run. In version 6.00 service pack A CitectSCADA will always only run on a single processor. This parameter sets which processor it will run on.

Process affinity information is now displayed in the general statistics kernel window and in the kernel dump file.

This supersedes knowledge base article Q3781 for CitectSCADA 6.00 service pack A.
