This section is for system administrators and high-level engineers who are setting up the preferences for Events Lists on either a system-wide, client-specific, or user-specific basis (see Set up the List Preferences).
ClearSCADA is supplied with a set of predefined defaults for the Event Journal and Events Lists. These affect, for example, the columns that are included on an Events List. If required, these options can be changed from the defaults. Some of these options affect Events Lists on a system-wide basis, whereas other options can be specified on a per-client (workstation) basis, or on a per-user basis.
(ClearSCADA logs events in the Event Journal. You can view these events by displaying the Events Lists.)
For more information, see the topics that are listed in the gray footer section at the bottom of this topic. Select the relevant entry to display the topic that you require.
In addition to the above, be aware that you can configure Historic Regions to stop events that have been logged within a specific time period from being deleted from the system. Such events are retained online and can be displayed on Events Lists. You configure Historic Regions using the ClearSCADA Server Configuration Tool (see Historic Regions in the ClearSCADA Guide to Server Administration).
