Please also see the attached screenshots. After a renovation of a machine where the power was switched off (also to the PLC) we have experienced many alarms where the operators are insisting that the alarm limits are not as they were when the machine was switched off. This past night we had to increase the HHA and HA limits in DB912 (in the first screenshot) - and they insisted it had been this high earlier. As can be seen in the other screenshot the DB should be retained and I thought that would hold the values even after a power off? What else should we do to ensure the alarm limits are not lost?
