I have created FB that is using ALARM_SQ block for creating alarms automatically.. When I compile the OS, tags are created by the STEP7 but for each alarm, it is created 2 tags which is named, "xx.EventRaw#1, xx.EventTrans#1"... this is increasing the tags.. How can I prevent this case?

I want both "Operator Control and Monitoring" feature enabled and ALARM_DQ function creating alarms automatically. In order to get ALARM_DQ working I have to enter "S7_server = alarm_archiv" vaule to a variable's attribute. It works OK, alarms are created on WinCC. Until I activate "operator control and monitoring" it does not create that additional tags (.EventState, .EventRaw# and .EventTrans#). However, I need to activate "operator control and monitoring" feature for some other reasons. Whether it is activated or not, alarm system works but it creates extra tags when activated. Thus, I think that tags are not important for operation and can be removed (which is not possible as they are read-only). Is there any way to prevent that extra tags being created? Or at least can they be removed?
