Historian combines trends, reports
InfoLink Process Historian from combines several software packages %%MDASSML%% Canary’s Trend Historian and Trend Link software; Software Toolbox’s symbol library; and optional XLReporter from SyTech %%MDASSML%% to provide a real-time and historical view of a process. With just a few keystrokes, an operator can call up historical data from any point in the past and review trends, HMI screens and reports exactly as they occurred.
InfoLink runs on any PC, including HMI workstations running HMI/SCADA software, and obtains its data via OPC interfaces to PLCs, DCSs, RTUs and other hardware and software packages. It stores data with tags and time stamps so it can be retrieved and displayed on screen in real time or in playback mode. Unlike some competitive process historians that use compression technology, InfoLink retains all the original data on disk. With compression, the other historians lose the resolution of the original data.
Screens can be easily designed to mimic HMI displays, or to present trends and comparisons. InfoLink can calculate and display KPIs in real time. Placing KPIs in a prominent location on the screen lets operators and users quickly see critical values that affect a process in real time or as it happened a month ago.
InfoLink integrates with XLReporter from SyTech. Data from XLReporter and Canary’s Trend Historian can be formatted into high-quality reports that can be stored in an HTML format, making them viewable via standard web browsers.
In Playback Mode, InfoLink is like having a DVR player that recorded everything that happened in real time, and plays it back at whatever speed is needed. InfoLink can even pause and step through events that occurred at a critical time. An operator can change from a trend display to an HMI screen with graphics, or put four different screens on the display at the same time.
