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).
