How to Use Function Blocks for Specific Operations
Section
1-4
51
To perform this specific operation
Perform the following
See page:
Constant transmission of
constants as analog signals
Use the Constant Generator block (Block
Model 166).
Setting of constants to specified
ITEMs under certain conditions
Use the Constant Item Setting block (Block
Model 171).
3-1 Configuration of
Function Blocks and
Function Block
Reference Manual
Constant
setting/selec-
tion
Selection of one of multiple
constants and transmission of
that constant as an analog signal
Use the Constant Selector block (Block
Model 165).
Function Block
Reference Manual
Analog signal
setting/
selection
Setting of analog signals to
specified ITEMs under certain
conditions
Use the Variable ITEM Setting block (Block
Model 171).
3-1 Configuration of
Function Blocks and
Function Block
Reference Manual
Selection of one of multiple
analog signals and transmission
of that analog signal as an analog
signal
Use the Input Selector block (Block Model
162).
Function Block
Reference Manual
Selection of the maximum value
from multiple analog signals and
transmission of that maximum
value as an analog signal
Selection of the minimum value
from multiple analog signals and
transmission of that minimum
value as an analog signal
Selection of the nth largest value
from multiple analog signals and
transmission of the signal as an
analog signal
Use the Rank Selector block (Block Model
161).
Function Block
Reference Manual
Switching of sensors on a
different measuring system or
measurement target
Use the 3-input Selector block (Block Model
163).
Switching of operation nodes on
a different measuring system or
measurement target
Use the 3-output Selector block (Block
Model 164).
Changing two settings with a
ramp (e.g., opening and closing
valves)
Use the Ramped Switch block (Model Block
167).
Analog signal
setting/
selection
Converting ranges of analog
signals merely by setting values
for 0% and 100% inputs and 0%
and 100% outputs
Use the Range Conversion block (Block
Model 127).
Comparison of constant and
analog signals
Use the Constant Comparator block (Block
Model 202)
Analog
signal/
constant
comparison
Comparison of two analog signals Use the Variable Comparator block (Block
Model 203)
Manipulation and monitoring of
ON/OFF valve with open/close
limit switches
Use the ON/OFF Valve Manipulator block
(Block Model 221)
Manipulation and monitoring of
motors
Use the Motor Manipulator block (Block
Model 222)
Manipulation and monitoring of
reversible motors
Use the Reversible Motor Manipulator block
(Block Model 223)
Manipulation/
monitor/
control of
special
external
control target
Manipulation of a electric
positional-proportional motor as
the control target
Use the Basic PID (Block Model 011)/
Advanced PID block (Block Model 012) and
Motor Opening Manipulator block (Block
Model 224)
