This field determines if an action can be applied after it has already been applied. See the Contingency Element Dialog topic for more details.
Time Delay
This specifies the time to wait in seconds before an action is applied. See the Contingency Element Dialog topic for more details.

The Contingency Definition Display is also used when showing Remedial Action Elements. This display will appear on the Remedial Action Definition dialog and when showing the Remedial Actions Display on the Options tab of the Contingency Analysis dialog. In addition to the fields listed above, the following fields are included:
Inclusion Filter
This is an advanced filter or device filter that determines if the remedial action element is applied with each contingency. See the Contingency Element Dialogtopic for more details.
Arming Criteria Added in Version 20
This specifies a criterion under which a remedial action element will be armed. See the Contingency Element Dialog topic for more details.
Arming Status Added in Version 20
This specifies how arming of the remedial action element is determined in the presence or absence of Arming Criteria. See the Contingency Element Dialog topic for more details.
Armed Added in Version 20
This specifies if the remedial action element is currently armed. This determination is made based on the present system state and might differ from how arming is determined during the contingency analysis process. Model Conditions and Model Filters have options that allow them to be disabled if they are true in the contingency reference state. These options are ONLY applied during the contingency analysis process and are not applicable when the value of the Armed field is determined.
In order for a remedial action element to actually be implemented, it must be armed based on its own criteria and the Remedial Action to which it belongs must also be armed. Remedial Actions have their own Arming Criteria and Arming Status that are described with the Remedial Action Definition dialog topic.
