.121 By default, the Lower or Upper Time Limit are not set. The Lower or Upper Time Limit can be activated by selecting them. The date and time limits can be defined by using the arrow buttons or by typing the information into the appropriate boxes directly. When the date limit is defined, the date selector component is displayed on the screen.
If the Lower and/or the Upper Time Limit has been selected in the upper part of the Filters dialog, the limits can be set by clicking Edit and by entering the desired date and time in the dialog which appears on the screen. In case the Lower and/or the Upper Time Limits in the Filters dialog have been selected, the fields below are unavailable but indicate the unselected date and time.
If the Selective Filter option is set, only the items concerning the substation in the drop-down list can be selected. This means that only bays that belong to the substation, are available in the Bay drop-down list. Similarly, only devices that belong to the selected bay, can be selected in the Device drop-down list.
If the Unselective Filters option is set, the items concerning bay and device can be selected in the respective drop-down lists without limitations. It is, for example, possible to select a device without selecting a bay or a substation. As a result, all the devices with the selected name will be displayed in filtered data, regardless of the bay or station. The lower part of the Filter dialog contains the drop-down lists where it is possible to select one alarm class out of the available alarm classes. When using alarm classes, the signals that have the same functional purpose are usually included in the same alarm class.
To view the other options provided, click the More button in the Filter dialog. You can select Save Preconfiguration, Load Preconfiguration or Advanced
Condition.

In this dialog, it is possible to define an advanced filter condition by using attributes found in the process database and by using a set of comparison operators and condition values. It is also possible to type in the filter condition directly in the Filter text box.

Selecting objects to the filter configuration
Search filtering can be done in the Filter dialog (see Fig. 6.4.1.-1) with the help of the five combo boxes. If Selective Filter is in use, the selections become active one at a time. For example, when the Substation drop-down list is selected, the Bay drop- down list becomes active. If Unselective Filter is in use, all the drop-down lists that are configured to be used in the system, are active. Option All is selected as a default, which is indicated as a star character in the drop-down list meaning that all the signals below the level are included.
