Hi Engineers 

Please can you help me how to acknowledge tp700 hmi alarm, I configured db word to trigger the alarms, I did offline simulation using plcsim, I could acknowledge the alarm using acknowledgment button on alarm page.i want to acknowledge the alarm using plc bit. I searched in chrome and found some ways but when tried it doesn't work for me.

In the HMI discrete alarm list, you can define a PLC tag for the alarm ack for each alarm.

I don't know how you have defined the Alarm bits and ack bits. I define them as an array of bool [0-255]. Then i just assing the absolute addresses of the array to the alarm and ack bits.

Hi

I tried it as you said and it worked.

Before, i was assigning alarm acknowledge bit from different int address, in the same data block. 

I Tought, it should be  integer address for alarm trigger bits and other different integer address for acknowledge bits.

I figured now, alarm acknowledge bits should be in the same word or array address of the alarm trigger bits.

(am I right?)

Thanks anyway for your help and support

Not the same array or word for either. Both need to have their own array of bools or words.
