When enabled (set to True), this attribute causes the integration in the NIE to place a system being viewed into a fast polling table. This attribute also places a system into a fast polling table on an object’s Focus view. This scenario provides faster updates to objects being viewed in any Metasys system UI. When viewing points from several systems, the Service Time for the NCM increases. Enabling this fast polling feature also affects the NIE service time.


  • To prevent delays in event reporting due to the fast polling operation, follow the existing report routing guidelines.
  • The NIE caches data read from each NCM at the rate monitored by the service time. Since applications use the cached values, do not enable the Fast Polling attribute if you are using any applications that require data to be updated within 2 minutes, or twice the normal service time, such as trend.
  • If you have Metasys system applications using polled values (such as Energy Essentials), do not enable this fast polling feature.
