Posted 16 Apr 2021 (edited) I have an existing LOGO!8 and im adding a HMI (SImatic HMI KTP400). i want to bring up an alarm based on the status of a Flag in the PLC. i can see that i cannot address an alarm to a Bool Tag. so my question is how to i get it to work. Example. i have LOGO flag 1 (M0.0) and Flag 2 (M0.1) what to i need to do to make them into a WORD for the alarms. Cheers Edited 16 Apr 2021 by Dave P Share this post Link to post Share on other sites
