Applies To:
  • CitectSCADA 5.xx, 6.xx
  • CitectHMI 5.xx, 6.xx
Summary:
I have noticed that my running CitectSCADA system loses screen focus randomly over time. When this occurs CitectSCADA is still able to update and display real time data but will not allow me to change the data value
or click on any button command unless I go into the Citect Kernel or into Windows task manager, where it will then recover from the screen focus.
 

Solution:
It has been found that CitectSCADA is not compatible with Schavlik generated program.
Schavlik is a program that is use to manage the installation of Microsoft Security patches.

Please ensure that you have the latest version of Schavlik or have it disable when running on a PC with CitectSCADA installation.
