What are tags?
Tags are data sets for GENESIS64™ to access external devices. The number of data sets used in runtime of GENESIS64™ are counted. In the example below, a device value of a programmable controller = 25 and an SQL statement that refers to the last week temperature data are targets counted.
In the case of Hyper Historian™
- When using Hyper Historian™, tags are counted separately from GENESIS64™*1*2
- “The number of historical data collection settings” are counted as the number of tags
