Point Service
The Point Service (PNT) is the CygNet point database service used to set operational parameters for real-time points in the CygNet system. A point record contains all configuration information about a point, including the name of its current value service (CVS), its Facility, Uniform Data Code (UDC), the Short ID and Long ID, description, engineering units, history retention period, alarm setpoints, scaling factors, notification options, enumeration conversions, etc.
The PNT manages alarm limits, conversion coefficients, description information, and other parameters necessary for real-time monitoring and control. One PNT can store point records for any number and any type of current value service (CVS). A point is required to see the data on a CygNet Studio screen, in a report, in a trend, or on a web page.
Accessing the PNT Service
Open CygNet Explorer to access the PNT service. In the service hierarchy (left pane), click Point Service (PNT) to view the contents of the Point Service in the service pane (right pane).
See CygNet Explorer for more information.
Configuring the PNT Service
The PNT Service configuration file must be edited to reflect the instance of the service; it must have an entry in the Address Resolution Service (ARS), and a record in the Remote Service Manager (RSM).
See PNT Configuration File Keywords for more information.
