System
alerts
System alerts are displayed
when
PC
2000 detects an
event
that
requires
the
attention
of
the
user.
Each
alert
is
automatically
categorised
depending
on
the
nature
of
the
event
and
the
response
required
by
the
user. The category
of
the
event
can range
from
a
warning
indicating
that
a service
parameter
is
out
of
tolerance
to
a process
abort
indicating
that
a process
setpoint
has been
out
of
tolerance
for
so
long
that
the
process
cannot
be completed. A
typical system
alert
is
shown in Fig 5.2.
