InfoLink Process Historian from Canary combines several software packages, including Canary’s Trend Historian and Trend Link software, Software Toolbox’s symbol library, and optional XLReporter from SyTech, 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.
