CENTUM VP Measures
MC
instrument
Answerback
check masking
when starting
MC instruments
Answerback check
masking continues until
the answerback check
masking time (MTM)
passes from the time of
starting MV regardless of
answerback input value
(PV value).
If the answerback input
(PV) value coincides
with the manipulated
variable (MV) output, an
answerback check mask
is canceled, FV value
HI/LO alarms, which
may subsequently occur
between MTMs, are not
masked.
Even if the PV and MV
coincide during answerback
check masking by the
specicationonlyafter
a lapse of MTM on the
answerback check mask
resolutive conditions in the
function block (MC-2, MC-
2E, MC-3, MC-3E) property,
answerback check masking
continues until the lapse of
answerback check masking
time (MTM).
Output hold
function when
the interlock is
true
When a custom-ordered
specicationbit(output
holdspecicationbitfor
MC instrument interlock
ON) in the FCS common
table is on, the output is
held when the interlock
istrue;ifitisfalse,the
normallyspeciedoutput
is provided.
No output hold function
is provided when the
interlock is true.
The output is held when the
interlock is true by specifying
[Effective]in[outputhold
function when the interlock
is true] in the function block
property;iftheinterlockis
false,anormallyspecied
output is provided.
High- and
low-limit
extension
function
When ML and
MH values
are changed
by operation
and monitoring
functions
When a regulatory
control instrument
carries out automatic
operation (AUT, CAS or
RCAS), if the MH value/
ML value are changed
by the operation and
monitoring functions, MV
values are then limited to
the MH/ML ranges.
When a regulatory control
instrument carries out
automatic operation (AUT,
CAS or RCAS), even if the
MH value/ML value are
changed by the operation
and monitoring functions,
the high- and low-limit
extension functions work,
and the MV values are
thus not limited.
High- and low-limit extension
functions are invalid when
Yesin[High/Lowbumpfree
capability] in the function
block detail builder is
specied;then,ifMHvalue/
ML value are changed by
the operation and monitoring
functions, the MV values
are forcibly changed within
the range of the MH and ML
values during the next scan
period.
When
transferring from
manual (MAN)
operation to
automatic (AUT,
CAS, RCAS)
operation
When regulatory
control instruments
carry out manual
(MAN) operation, if it is
transferred to automatic
operation while MV
values exceed the
limits of the MH and ML
values, the MV values
are then limited to the
range of the MH and ML
values.
When regulatory control
instruments carry out
manual (MAN) operation,
even if it is transferred to
automatic operation while
MV values exceed the
limits of the MH and ML
values, the high- and low-
limit extension functions
work, and thus the MV
values are not limited.
High- and low-limit extension
functions are invalid when
Yesin[High/Lowbumpfree
capability] in the function
block detail builder is
specied;then,ifchanged
to automatic operation while
the MV value exceeds the
limits of the MH and ML
values, the MV values are
forcibly changed to MH or
ML values during the next
scan period.
CALCU CPV
range
CALCU CPV
range limit
Data exceeding the
scale high- and low-limit
values are not present
because numeric data
are processed as
normalized data taking
the value from -1 to 1.
The numeric character
data are treated as
engineering quantity
involving data beyond
scalelimits;therefore,
it is necessary to add
calculation blocks for
range limits.
SpecifyingYesin[CPVL
range limit] in the function
block detail builder makes
the CPV value of CALCU/
CALCU-C coincide with SH
if the CPV value exceeds
SH and with SL-(SH-SL) if
the value exceeds SL-(SH-
SL).
