Execute a Function on changes of a Float Variable

Execute a Function on changes of a Float Variable

Hello,
I use Zenon 6.51 version and want to ask a question. I try to execute a function on every change of a float variable. The variable is read from a SQL Server with SQL-Driver and its update time is nearly 15 minutes.
Can you help,
With Best regards,
