Hi Marco,
Check out the event manager of the C-More EA9.

Add a tag in the productivity software as normal, and program it in ladder logic.
In the "tag database" write down the value in the "system ID" column for that tag. (if it's a Boolean tag, it should be "C" followed by a 6 digit number.)
In the C-More tag database, add a tag, make sure the device name is selected for your productivity, add a name, and set the address to the system ID you wrote earlier.
then, use that tag you just created to create an alarm, or indicator on the HMI.
