handling.
Local Override (LO):
Applies to control and output
blocks that support a track
input parameter. Also, a local
lock-out switch on the device
may be provided by a
manufacturer to enable LO
mode. In the locked out
mode, the block output is
being set to track the value of
the track input parameter.
The algorithm (for analog
devices) should initialize so
that no bump is experienced
when the mode switches
from LO back to the target
mode.
Manual (Man):
The block output is not being
calculated, although it may
be limited. It is directly set by
the operator through an
interface device. The
algorithm should initialize so
that no bump is experienced
when the mode switches.
Automatic (Auto):
The block output is
calculated using the input
from the TB in case of an
input FB and using a set
point value provided by a
host or an operator through
an interface device in case of
an output FB. For PB and TB
this mode indicates that their
block functions are able to
work.
Remote Cascade (RCas):
The block set point is being
set by a Control Application
through the remote cascade
parameter RCAS_IN. Based
on this set point the normal
block algorithm determines
the primary output value.
