Closing Previous Protection Scheme Events

When a protection scheme event is generated as a result of a background integrity check then any previous protection scheme events (whether generated as a result of a previous integrity check or as a result of a topology change) will be automatically closed by the system if they are still active and not currently in progress.

Understanding the Number of Retries for a Timed Out Step

If no response (related to a switching action) from SCADA is received within the configured timeout period, then the switch step status will be set to a value of Failed. When the Protection Scheme plan is executed in automatic mode or when the plan is manually executed using the Execute the entire plan toolbar option, the plan execution can retry a timed out step for a configurable number of times before it sets the switch step status to Failed.

Configuring the Number of Retries for a Timed Out Step (Administration Users)

To allow the plan to retry the actions when they time out, configure the rule DMS Switching Step Fail Retries and Wait Time in the Configuration Assistant Event Management Rules tab’s DMS Application Rules tree.

Note: The rule may be searched for or you may expand DMS Application Rules and then SCADA Measurement Rules.

Add an instance of this rule for Protection Scheme plans. Configure the following:

• rule_value_2: Enter the Protection Scheme sheet class (found in the SWMAN_SHEET_CLS table).

• rule_value_integer_1: Enter the maximum number of retries to perform before setting the step as Failed.

• rule_value_integer_2: Enter the time to wait before retrying the action.

See Using the Event Management Rules Tab for more information on configuring rules.
