June 5, 2013 - Metso updated the DNA automation system. Enhancements include tools for alarm shelving, a function test, and an IEC 61850 interface.
Alarm shelving hides nuisance alarms temporarily
Metso has developed an Alarm Shelving application. With it, the operator is able to temporarily prevent an alarm from being displayed when it is being more of a nuisance. A shelved alarm will be removed from the alarm list and will not show until it is un-shelved. In the application, the user can shelve an alarm, possibly comment on it and define the length of the shelving time. The shelved alarms are hidden in the user interface until expiration.
Improved function test
Metso has further developed its function test for testing control applications. It shows the function block diagram with live values from the running environment – real or virtual – thus helping to solve both control and process disturbances. The application features automatic data collection, resulting in faster analysis. Usability is boosted by simpler functionality; there are fewer buttons to push and an improved version of the function test toolbar.
IEC 61850 interface available
Metso DNA is available with an IEC 61850 interface, an international standard data communications protocol with several services aimed at all substation protection and control requirements. Metso controllers receive data from IEC 61850 server devices either by cyclic polling or using event-based reports. They can also send data or commands to IEC 61850 server devices. The client provides a native IEC 61850 interface according to the IEC 61850 standard. Configuration of the IEC 61850 interface in Metso DNA is defined in ASCII files, which are loaded from the backup node when the ACN node is starting.
