Show latest event formula

[scadarapid]

Hi.

If I have 3 doors and I have 1 Dynamic Text on my scheme. Then, I need to know the latest event which door is close. example Door1 is opened, Door2 is opened, Door3 is opened.
when Door1 is close the Dynamic Text on the scheme will show Door1 is close then, Door2 is closed the Dynamic Text on the scheme will Show Door2 is closed, after that Door3 is closed the Dynamic Text on the scheme will show Door3 is closed, then, Door2 is opened and it close the scheme show door2 is closed.

I need to know the latest events.
How can we write the formula?

Thank you so much.

Hi,

You should create an extra input channel of the calculated type.
In the channels of particular doors use SetVal(…) to set the calculated channel.
