Send control when unack alarm is raised

Send control when unack alarm is raised

Afternoon,

I was wondering what the best method would be for activating a control output when there are unacknowledged alarms standing in the system.

In my case I would like to activate an external alarm (eg a Klaxon) by sending a control to my RTU (via DNP3 in this case, but I imagine the same applies for other protocols), which will then latch on / off a relay.

I understand that I can create a variable for unacknowledged alarms. I can then link a reaction matrix to that so if the value is > 0 I can send a function. I'm just not sure the best way to send the control. Should I use a 'driver specfic command' to write a value directly to the DNP3 driver? Should I do it via 'command processing'?

As a follow up question.. can I do something similar but based on certain alarm groups rather than just any unacknowledged alarm?

Appreciate your inputs on how to go about this in the best way.

Thanks,

Dave
