Split from Discrete alarm in TIA portal V13.

Hello 2362,

to configure an alarm you need a trigger tag.
Configure an normal HMI tag with connection to the LOGO!.
This FAQ can help you with that: https://support.industry.siemens.com/cs/ww/en/view/56348902

With "digital alarms" you mean "discrete alarms"?
Just add a new discrete alarm and connect with the trigger tag.
Choose message text, alarm class and so on.

Not: You can access Boolean tags directly.
You can "group" them and access them as a Word tag or similar:

Hi,

e.g you need to "group" the boolean tags in a Word, in PLC. Else, each boolean tag should be declareted as word in HMI.
To group, there is many ways: you can use absolute addressing. So, M0.0, M0.1 ..etc. are boolean variables but could be read as MW0 in the HMI.
