Hi Benjamin,
When you configure the Arduino as an IO as described in the Guide to IO System, you continuously will receive values from the configured analog and digital inputs on the Arduino board. With the Sev utility, a database for process history, these values can be stored in a mysql database by configuring a SevHist object for every Ai och Di signal that should be stored. For each signal the value and time is stored in one table in the database. The stored values can then be displayed in a curve window in the operator environment or in sev_xtt.
