Check if alarm is aknowledged via MsgNr

Neschner Posts: 3 Rating: (0)	Is it possible to check if an alarm is aknowledged or not if only the MsgNr is known? The only way I can currently think of is by remembering the alarms/message I get with the callback of 'MSRTStartMsgService' and if those alarms are aknowledged or not.

Neschner Posts: 3 Rating: (0)	I know about the status tag but to read it, I need to know which bit I need to read and also what the name of the status tag is. So I guess it's not possible to get the information if an message/alarm "Came In / Went Out" or needs acknowledgment with just knowing the message number?
