calculation
SUB terminal provides
the following output if an
IOP occurs:
∆PV=0or∆CPV=0
If an IOP occurs, the
function block provides
∆PV(calculationblock
provides∆CPVoutput)
even when PV value
overshooting occurs. (If
overshooting does not
occur,both∆PVand
∆CPVare0asPVvalues
do not change even if an
IOP occurs.)
When the FCS property’s

specied,theSUBterminal
provides∆PV=0or∆CPV
= 0 output when an IOP
occurs.
Totalizer data Data set to
totalizer value
Even if the instrument
totalizer “NO” is
specied,itispossibleto
set data to SUM values.
If the function block
totalizer“NO”isspecied,
it is not possible to set
data to SUM values.
Specifyingthe[SumValue
Entry] menu in the function
block detail builder makes
data setting to SUM values
from HIS possible.
CALCU/
CALCU-C
pulse train

Totalizer data
specication
with pulse train
inputs (batch
data totalizer
type)
– If the pulse train input
(batch data totalizer) is
selected with CALCU, RV
rather than CPV is used
for totalization.
IfCPVinthe[DataItemfor
Totalization] menu in the
function block detail builder
isspecied,CPVisusedfor
totalization.
PID-TP
instrument
PID-TP control
algorithm
The method of selecting control algorithms differs
between CENTUM-XL and CS or later systems, so
differential control action results in CAS mode.
In CS or later systems, only PV proportional and
derivative-typePIDcontrol(I-PD)isused(xed).A
buildersuchasaPIDblockcannotbespecied.
The[PIDcontrolalgorithms]
menu in the function
block detail builder allows
the selection of control
algorithms identical to PID
algorithms, as given below:
• ProportionalPVDerivative
Type PID Control
• PVDerivativePIDControl
• BasicTypeID
• AutomaticDetermination2
• AutomaticDetermination
Output action – Positionaltype(xed) [AuxiliaryOutputType]
menu in the function block
detail builder allows the
selection of positional or
velocity output action.

Specifying[CENTUMV/

in the function block detail
builder allows batch starting
or restarting depending on
the conditions with ACT.
ON descriptions on the
sequence table, or the like.
Restart during
EMST
Restart is accepted even
during EMST.
Does not restart under
ZONE8(duringEMST
or while MV values are
decreasing).
Specifying[CENTUMV/
CENTUM-XL Compatible] or
[CENTUM-XLCompatible]
in the function block detail
builder can accept restart
instructions when BSTS =
EMST (while MV values are
decreasing in an emergency
stop).
