PI System



Unlike a DCS or HMI that can display real-time data within a short term time horizon, the PI System allows manufacturing sites to view data real-time as well as easily look back at data from years ago. There are times when it's useful to graphically overlay or compare tabular data from multiple time ranges (ex. compare a current production campaign against a known good production run from a year ago).

The OSIsoft PI System with real-time data acquisition offers a central repository for data through a facility or across multiple locations. Information can be automatically collected from many different sources (Control systems, Lab equipment, Calculations, Manual Entry, and/or Custom software). Most information is gathered using one of the many OSIsoft and third party PI Interfaces. Users can then access this information using a common set of tools (ex. Excel, web browser, PI ProcessBook) and look for correlations:

    Analyze seasonal trends
    Determine if utilities is not meeting the demands of production
    Compare the performance of different lots of raw material
    Determine when maintenance is required on equipment
    Optimize the utilization or performance of a production line

Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into ...
