„ OPC Alarms and Events Plug-In m B^^^ KEPServerEX - Communications Platform Kepware's OPC Alarms and Events Plug-In for KEPServerEX can help users reduce costs and improve performance by allowing OPC AE clients receive and monitor process alarms, operator actions, informational messages, and to track and audit messages directly. Users can now monitor areas of a process that require operator attention when defined thresholds are met (such as event detection, abnormal situations, and the equipment's safety limits). The Alarms and Events Plug-In can also be used to identify faulty equipment, create maintenance work orders, improve operators'effectiveness, and collect and record alarm and event information for audits to use with other historical data. OPC Alarms and Events Features OPC Alarms and Events is a plug-in module to Kepware's industry lead- ing communications server, KEPServerEX. It works in conjunction with KEPServerEX's free Alarm and Events (AE) Client Interfaces. Users start by creating an alarm, which is as simple as browsing KEPServerEX's tags and then selecting an item that will be used as the alarm. Once an item is chosen, users must set its condition and sub-condition. A trigger can be then be specify to compare the current data value with the thresh- old. When the condition's trigger is met, an alarm will be sent to the corresponding Alarms and Events client application that provides the user with unique alarm input, output, and acknowledgement messages.

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 the Alarm and Event Plug- In, users must both use and configure the OPC DA Driver and/or the OPC UA Client Driver. ^> KepwareTechnologies | 400 Congress St. 4th Floor | Portland, Maine 04101

Communications for Automation | 207.775.1660 Full OPC AE Client Severity Support The severity value (which is commonly called the “Priority” in relation to process alarms) is an indication of the sub-condition’s urgency. The valid range is 1 to 1000, with 1 being the lowest severity and 1000 being the highest. Typically, a severity of 1 indicates an informational event, whereas a value of 1000 indicates a disastrous event. Extensive Alarm Condition Support KEPServerEX supports nine OPC AE standard conditions, thus providing users flexibility when calculating and prioritizing the Alarms and...

Communications for Automation | 207.775.1660 • DEV_HI, DEV_LO Deviation conditions have a single sub-condition that matches the condition name. They are used to monitor the deviation of the source, and to trigger the condition if the source exceeds the limits set by the deviation. For example, this condition should be used if utilizing a source that monitors power consumption, and when users want to trigger the condition if the power consumption is outside of 100W ±20%. Because the conditions are the same functionally, users should select one with a name that makes the most sense for the...
