Hi,

I've tried to do that when M2.6 memory bit becomes 1, an alarm will be seen on HMI screen until it is been acknowledged. All configurations I've made can be seen in the attachment. But when I download and run the program no any alarm seen on HMI although M2.6 becomes 1. I dont know whether I omit a configuration or not. Can you help me?

Best regards.

Hello,

The variable 'Alarm_word' should be an integer. (Change datablok instead of Booleans, change to Integer or Word)

Then the orange color will disappear and then the Alarm text will show.

Best regards,

I've done you say but I've gotten the error in the attachment.

Hello,

In the datablock, you define the variable of type Integer or Word.

Then in the PLC, you can set every Alarmbit.

Because DBy.DBW0 is the same address like DBy.DBx0.0 till DBy.DBx1.7

Best regards,

Hİ,

I've managed to activate alarms not by defining an array of bools but int data type. Thanks anyway. Alarms pops up on the HMI screen but I also want to acknowledge alarms on HMI screen. To do that what should I write to main program block?

Thanks.

Hello,

You want to acknowledge alarms by controller or by HMI?

Best regards,

Wizard
