The Universal Interface Service (UIS) is the primary interface between field devices and CygNet devices. As the primary data collection service, the UIS is often called the "workhorse" of the CygNet system. It collects data for the devices stored in the Device Definition Service (DDS) and can store real-time records for up to 500,00 points for a 32-bit UIS and 5,000,000 points for a 64-bit UIS.
Using CygNet Explorer, you can view current values for device points, as well as various device statistics for remote, communication, and import/export devices. The UIS works closely with the DDS and Master Scheduling Service (MSS), among other key services.
Both a 32-bit UIS and a 64-bit UIS are available.
Note: It is recommended that you run any CVS with more than 256,000 points on a 64-bit operating system.
Note: For a 64-bit UIS, if using more than 500,000 points, ensure that the system has sufficient CPU and memory when designating the maximum point limit, as too many points can severely impact a system's performance.
