Step 25:
Switch alarm output contacts to latching type.
Note: The latching mode of the flow alarms is only reflecting to the alarm
output contacts, and NOT to the Alarm Status in the AI transducer block.
Once PV value has reached either > 90 or/and < 10, alarm output contacts
A and B remain closed after reaching no alarm condition.
To open alarm output contacts A and B again, an alarm reset is needed.
