Hello, 

I have an 840D sl with Sinumerik PCU V04.08+SP04+HF01, I added PLC alarms texts according to the manuals from the screen, Menu Select > Setup > HMI > Alarm Texts and it works on most of the machines in here, except one machine. It displays the alarm number on top when the alarm is ON and instead of showing the alarm text that I entered, it shows "124.0 -              " or "124.1 -             " where it is supposed to display the alarm text.

There are other old plc alarms that are working well,  but they are not listed on the alarm texts screen that I am using but they are displayed in similar formats as the alarms above "123.0 - alarm example". So I am assuming that there is another file that includes these alarms and they are overwriting the alarm texts that I added. 

Can someone help please?
