Posted 21 Nov 2022 (edited) Hi, This is my first application working with a Mitsubishi HMI GT2107-WTBD using GTDesigner 3. Is it possible to have an Ack bit going from the HMI to the PLC when the operator acknowledges an alarm? I've found how to set up comments for alarms and trigger alarms but can't figure out how to link an ACK bit back to the PLC. Thanks.

Posted 21 Nov 2022 From menu select Object->Switch->Switch. Then put button where you want. After that select that switch/button properties and first add "Action (Key code)", then select Key Code Type "Alarm display" and Action FFB4/"Check the selected alarm status to "Checked" (Check)", or FFB5/"Check all the alarm statuses to "Checked" (Check all)". After that add another action, but this time Action(Bit) and select what bit do you want to change in PLC and how. Share this post Link to post Share on other sites
