Applies To:
  • CitectSCADA 4.xx, 5.xx
Summary:
History files may not rollover at the appointed time or may rollover too often. A history file will not be produced if no alarms occurred during the last history period. 

Solution:
The normal operation of Citect is that a history file will not be produced if no alarms were logged for that period. An enhancement has been added which will create an empty history file in these cases. This feature can be enabled with this setting in the citect.ini.

[Device]
AlwaysCreateHistory=1

CIT has confirmed this to be a problem in Citect for Windows versions 4.XX to 5.21 Spk F. This problem has been fixed in version 5.21 Spk G.
