ITEM BROWSING AND IMPORTING

Browse KEPServerEX to find and import available tags for testing. Tags can represent specific areas and equipment on the plant floor. To make third-party OPC DA and OPC UA Servers available for use with Alarm and Events, use and configure the OPC DA and/or OPC UA Client drivers.

FULL OPC AE CLIENT SEVERITY SUPPORT

The severity value is an indication of the urgency of the sub-condition. This is also commonly called "priority," especially in relation to process alarms. Values range from 1 to 1000, with 1 being the lowest severity and 1000 being the highest. Typically, a severity of 1 would indicate an event that is informational in nature while a value of 1000 would indicate a disastrous event.

EXTENSIVE ALARMS AND EVENTS CONDITION SUPPORT

KEPServerEX supports nine OPC AE standard conditions, providing flexibility in how Alarms and Events Conditions are calculated and prioritized. Each condition has a unique name and a unique set of sub-conditions.

• MULTI_LEVEL
  The multilevel condition supports multiple sub-conditions. This condition is used if the source has multiple states of interest and there is a need to know the transition between the condition states. For example, if you have a temperature tag with multiple temperatures of interest, use this condition. The HIGH_HIGH sub-condition has the highest priority and the LOW_LOW sub-condition has the lowest.
• HIGH_HIGH,HIGH,LOW,LOW_LOW
  These are single level conditions with a sub-condition that matches the condition name. These conditions are used if a single state of a source is of interest. For example, if you have a temperature tag with a single temperature of interest, use this condition.
  
  Note: Use HIGH_HIGH for higher priority states and LOW_LOW for lower priority states.
• ROC_HIGH,ROC_LOW

  This condition compares the source data to a static or dynamic ROC. For example, if you have a source tag that represents production output and you want to trigger the condition if the output falls below 100 units a minute, use this condition.
  
  Note: Use ROC_HIGH for high priority conditions and ROC_LOW for low.

• DEV_HIGH,DEV_LOW
  These conditions monitor the deviation of the source data. The condition is triggered if the condition of the source is outside the limits set. The limits can be either a percentage or a static value. For example, if you have a source that monitors power consumption and you want to trigger the condition if the power consumption is outside of 100W ±20%, use a deviation condition.
