Five types of events can be configured:
SEVERE ALARM
ALARM
FAULT
WARNING
ANOMALY
A further table, called the Description Table specifies how the message is to be dis-
played on the monitor screen.
User operation (such as alarm acknowledge and reset) or field events (e.g. automatic
or manual control panel reset) can change the points' state. In this case the new point
value is displayed accordingly to the description and treatment tables as configured.
In the integrated system the FSS operator is able to see a subset of the states of a se-
curity point, plus a subset of the commands. In particular, the reset command can be
issued only from a LMS station and never from an FSS station.

2.3.2 Technological blocks
The FSS basic unit of information recognised by FHI_Pad is a block. The FHI Pad
keeps a table that is an image of the FSS technological points seen by LMS.
At the present state of implementation analogue blocks cannot be fully treated, i.e.
analog point alarms can be displayed and treated but the analog value measured can-
not be displayed.
The integrated system lets the operator activate a digital output and acknowledge/reset
an FSS block status.
