The historian runs on any PC, including HMI workstations running HMI/SCADA software, and obtains its data via OPC interface to PLCs, DCSs, RTUs and other hardware and software packages. Other features include data storage with tags and time stamps, data-disk retention, and calculate and display KPIs in real-time. Placing KPIs in a prominent location on the screen lets operators and users see critical values that affect a process in real-time or as it happened a month ago, the company adds. With the software, a user can create industry standard graphic symbols from Software Toolbox and more than 4,000 different symbols are available. The historian integrates with XLReporter from SyTech and can be formatted into high-quality reports that can be stored in an HTML format.
