Today, we want to talk about scale. Scale matters in the real-time information world. Scale matters with process data. Scale matters for large enterprises.
For the ones of you, who have not spent the last years close to automated production and control systems: The term “Tag” refers to a named item or object in this domain – usually associated to some moving data properties and classified by a certain designation system. Designation systems in industry can be compared to stock market tickers. Everybody understands that MSFT.NAS refers to the share price of Microsoft at the NASDAQ stock exchange. Similarly, a control engineer understands that TC40101.PV is the current process value of the controlled temperature of tank 10 in area 40 of a distinct production plant. Or so. Unfortunately, industrial designation systems are not finally regulated on a global scale, as stock ticker symbols are. Money always wins.
