Set the AlarmState of a Time point

[IvanDeMarco97]

Hi everyone,
I would like to send an email when a Time point has not changed for at least 30 minutes.

I created a logic that checks this and sets a digital point in alarm. Then I used Email Action to send the email.
However, I would need to have the last update date, which I cannot write in the Email Action.
Can I write in the message the value of a database variable that is not the one that calls it?

If I can't, I should use the date to send the email, but I don't understand how to put it in alarm...

Thanks!

A trip sequence in an email redirection action can only access properties of the source object of the alarm (the digital point). There isn't a way to include properties of arbitrary other objects (such as the time point).

One solution would be to have the logic program copy the required last update date from the time point into a custom DB data field in the digital point which can then be inserted into the email.

Another solution would be to create a custom DB reference configuration field in the digital point and use this to link the digital point to the time point. The trip sequence can then use the reference field to access the properties of the associated time point, e.g. %OMyCustomRefFieldId.CurrentTime%.
