Yes I have lines in my programme where i use UALM[x] which trigger my UALM.
When I disable the interconnect USRALM signal, the manual set/reset of the DO working.
I tried to change severity level of my UALMs too but the problem is same
Another point, when an user alarm is active, the system variable "Systeme variables > $ALARM_IF > $LAST_UALM" stay empty.
However "$LAST_ALM" display the active user alarm but all others alarms too
It's like my User alarms was not recognized like UALMs.
