I see few properties of security being used to connect to the OPCUA Server: I do not understand how the security works here,ĭiscussing about client-example provided by eclipse-milo 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 ☒0%, use a deviation condition.I am new to this OPC-UA world and Eclipse Milo. The limits can be either a percentage or a static value. The condition is triggered if the condition of the source is outside the limits set. These conditions monitor the deviation of the source data. Note: Use ROC_HIGH for high priority conditions and ROC_LOW for low. 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. This condition compares the source data to a static or dynamic ROC. Note: Use HIGH_HIGH for higher priority states and LOW_LOW for lower priority states. For example, if you have a temperature tag with a single temperature of interest, use this condition. These conditions are used if a single state of a source is of interest. These are single level conditions with a sub-condition that matches the condition name. The HIGH_HIGH sub-condition has the highest priority and the LOW_LOW sub-condition has the lowest. For example, if you have a temperature tag with multiple temperatures of interest, use this condition. 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. The multilevel condition supports multiple sub-conditions. Each condition has a unique name and a unique set of sub-conditions. KEPServerEX supports nine OPC AE standard conditions, providing flexibility in how Alarms and Events Conditions are calculated and prioritized. Extensive Alarms and Events Condition Support Typically, a severity of 1 would indicate an event that is informational in nature while a value of 1000 would indicate a disastrous event. Values range from 1 to 1000, with 1 being the lowest severity and 1000 being the highest. This is also commonly called "priority," especially in relation to process alarms. The severity value is an indication of the urgency of the sub-condition. 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. Tags can represent specific areas and equipment on the plant floor. When the condition's trigger is met, an alarm will be sent to the corresponding Alarms and Events client application providing the user with unique alarm input, output, and acknowledgement messages.īrowse KEPServerEX to find and import available tags for testing. A trigger is then set comparing the current data value and the threshold. Once an item is chosen, a condition and sub-condition need to be set for the item. Creating an alarm is as simple as browsing the existing tags within KEPServerEX and selecting the item that will be used as the alarm.

Furthermore, it can be used to collect and record alarm and event information for audits or used in correlation with other historical data.Īlarms and Events is an advanced plug-in to Kepware's industry-leading connectivity platform, KEPServerEX, and works in conjunction with the platform's free OPC AE server interface. Alarms and Events can also be used to help identify faulty equipment, create maintenance work orders, and improve operators' effectiveness. Users can monitor areas of a process that may require operator attention when defined thresholds are met, including safety limits of equipment, event detection, and abnormal situations. OPC Alarms and Events (AE) clients can receive and monitor process alarms, operator actions, informational messages, and tracking/auditing messages directly from Alarms and Events. Alarms and Events for KEPServerEX can help reduce costs and improve performance.
