Ack connection

When the application starts, this connection has a value of zero.

When the operator acknowledges an alarm by pressing the

Ack Alarm

button, the application sends the alarm's trigger value (or bit position, for bit triggers) to this connection, and holds the value as long as the operator presses the button, or for the duration of the notification hold time, whichever is longer. Then the connection's value is reset to zero. Specify the hold time on the

Advanced

tab.

When the operator acknowledges all alarms by pressing the

Acknowledge All Alarms

button, the application sends the Acknowledge all value (specified in the

Use ack all value

box) to this connection, and holds the value as long as the operator presses the button, or for the duration of the notification hold time, whichever is longer. Then the connection's value is reset to zero.
