Can Someone please suggest to update the status of PLC ACK bit when the Alarm is Acknowleged from HMI
I have also gone though some FAQs & followed few instructions (/tf/WW/en/Posts/32645)
that usesSFCs (for Alarm Generation).

I havent used in my project such SFC.
I have used Comparators and Alarm Generation takes place accordingly

Is Writing an FB the only option ? like this one /tf/WW/en/Posts/22133

or can someone suggest any scripts ?
