did you know if it is possible to use one bit for one aralm word data acknowledge?

 Hi vorapob, I might be facing the same problem as you...

See attached what I´ve done, maybe it helps you. IMPORTANT: click on the columns on alarms page to display ALL COLUMNS...

My idea was to have a button to ACK all errors together, it seems it´s working...perhaps one of the forum experts could also tell me if this idea is OK or not...I didn´t understand very well the difference between HMI ACK and PLC ACK...

Dear qwazee,

Thank you for you detail but something I still not clear.

Can you share a project example the way how to acknowledge in HMI and how to acknowledge by PLC ?

For PLC acknowledge operator can press reset button from anywhere to do it.

Best Regards,

Vorapob

Split from How to use button in order to acknowledge alarm ?.

One way to ack all alarms is in HMI insert Button with event then pressed  >> AlarmViewAcknowledgeAlarm (tested and worked)

Another way is in HMI insert Button with event then pressed>>SetBitWhileKeyPressed  >>assign PLC bit,>> that bit use in program then it's active write to acknowledge word like in BIN:= 2#1111 1111 1111 1111 or in HEX:=FFFF or in DEC:=65535 (not tested)
