CALCU System
alarm upon
occurrence of a
calculation error
Even if a calculation
error occurs in
operational expressions,
no system error is
submitted.
If a calculation error
occurs in operational
expressions, a system
error is submitted.
Ifyousetthe[Restrain
system alarm when CALCU
calculation error occurs]
in the FCS properties
to "ON", a system error
is not submitted during
operational expressions.
Change of
CALCU input/
output limit
range
Input data/output data is
limited within a range of
±1 as normalized data.
Input data/output data is
not limited within a range
of ±1 as normalized data.
Thespecicationisrevised
so that input data/output
data is limited within a
range of ±1 as normalized
data.
Change of
normalization
target data
Data items that indicate
range upper/lower limit
value are non-target
items of normalization.
Data items that indicate
range upper/lower limit
value are not non-target
items of normalization.
Thespecicationisrevised
so that data items that
indicate range upper/lower
limit value (SH/SL/ SSH/
SSL/ MSH/MSL/ DSH/DSL/
MSH1/MSL1/ MSH2/MSL2)
are non-target items of
normalization.
Operation in
cases where
nothing is
substituted
for CPV in
operational
expressions
If nothing is substituted
for CPV in operational
expressions, this
function is operated
assuming that
expression CPV=RV
exists at the end of
expression
There is no such
assumption.
Change so as to operate
assuming that expression
CPV=RV exists at the end
of expression if nothing
is substituted for CPV in
operational expressions.
PRD mode Change to the

during CAL
Possible to change to
the PRD mode even
during CAL.
Even if CAL is entered
in the PRD mode, MAN
fall-back is not made.
Not possible to change

CAL.
If CAL is entered in the
PRD mode, MAN fall-
back is made.
If “Permit PRD mode during
CAL (XL compatible)”
is selected from builder
specicationitems,the
PRD mode can be changed
during CAL. (*1)
Even if CAL is entered in
the PRD mode, MAN fall-
back is not made.
If CAL is entered when a
block mode is any of AUT/
CAS/RCAS/ROUT, the
MAN mode appears as
usual.
*1: Version upgrade of HIS
is also required.
Output limiter Output limiter in
the RPD mode
In a cascade-connected
internal instrument,
the output in the PRD
mode is limited with the
secondary tag MH/ML.
In a cascade-connected
function block, the output
in the PRD mode is not
limited with the secondary
tag MH/ML.
By specifying ON for the
"Enable output limiter
in the PRD mode (XL
compatible)" checkbox, the
output of the primary tag is
limited with the secondary
tag MH/ML.
