Citect Scada 7.2 Help on monitoring multiple Tags

Hi, I´m doing my first application in Citect. This application is a simple digital inputs (almost 70 tags) monitoring application and writing this into a SQL database.
I need to know what´s the best way to detect any change on the tags (70 digital tags) and when a tag change write all tags into the SQL database.
I´ve analized Events, trends and alarms and still don´t know how to do it.
Any suggestion on where should I start?

Dear marcelo_lalala,

You can write a CICODE function to update already created Database. When your tag changing (according to your statement it is 0 or 1), Just call the function.The sql command for CICODE can be reffered form manual.(CitectSCADA 7.20 Cicode Reference Guide.pdf)
