Hello Neschner,

you could configure an internal tag/bit as status tag
for every single message.

see manual:
"SIMATIC HMI WinCC V7.5 SP1 WinCC Information System"
"The status tag of a message"

https://support.industry.siemens.com/cs/ww/en/view/109772961/82200466955

Here can you check, if the message is acknowledged or requires acknowledgment.

Hello Neschner,

alternatively, you could read out the Alarmlogging Archive with
VB-script, and check the last state of a special message number.

see Application example:
"Export of archive data using the SIMATIC WinCC/Connectivity Pack
(OLE DB Provider)"

https://support.industry.siemens.com/cs/ww/en/view/38132261

Or you configure operator messages in the Alarm-Control
for the Acknowledge of messages.

see manual:
"SIMATIC HMI WinCC V7.5 SP1 WinCC Information System"
"How to configure operator messages"
