Analog Alarm

The standard configuration uses four thresholds, defined as follows.

An alarm is not clearable until the device in alarm is back in a normal state.

The analog alarm value H123\H456\H78\Val\PVA stays at the alarm level,

until it has been acknowledged by the operator with the display acknowledge

button

. An analog alarm counts as 1 alarm, even if two messages are visible in

the alarm list (for example, High-alarm and Max-alarm).
