Tia Portal Discrete Alarms - switching off falling edge ?

[mihal__]

Is there any possibility to switch off alarm trigger mode "falling edge" in discrete alarms configured in Tia Portal ?

I have an alarm configured as discrete and I want to print a message on the screen when my bit changes from zero to one - and it works fine. But, when this bit changes back from one to zero, a message is printed again - is there any way to switch off this falling edge detection? I have nowhere found trigger mode for discrete alarms. I suppose that there has to be somewhere sth like this...

I really don't like this Tia Portal style alarm configuration :/

You are probably simply displaying alarm conditions without having a memory of if the alarm is acknowledged or not.
You have to add the functionality that keeps a memory of the alarm until it is acknowledged.
You then set the alarm view to display unacknowledged alarms rather than all alarm events.

Aside from that, I do not recommend to have a window that pops up over the regular screen. It will be very annoying if there are frequent alarms.
Instead create a smaller alarm banner that displays just the most recent alarm.
And create a separate screen to display a list of all current unacknowledged alarms, and yet another screen that displays a historic list of alarm events.
