How to Use Function Blocks for Specific Operations
To perform this specific operation
Analog ON/OFF control
control
Heating/cooling ON/OFF control
Time-proportional control
Continuous proportional control for heat-
ing/cooling
Application of input filter on PV
Application of bias on PV
Application of ratio on Set Point and PV
Inputting the difference between two PVs Use the Addition or Subtraction block (Block
Entry of differential pressure transmitter
to calculate flowrate
Entry of pulse output flowmeter for accu-
mulation of flowrate
Temperature and pressure correction
Setting of the PID constant values for
multiple words
Switching of multiple Set Point values
Switching of multiple PID sets
Setting multiple SPs and PID constants,
and switching the SPs and PID constants
under certain conditions.
Examples:
• Switching set values (SPs, PID con-
stants) according to product type.
• Switching set values (SPs, PID con-
stants) according to time.
Ramp control of Set Point values (pro-
gram control)
Cascade control
Dead time compensation control
Feedforward control
Non-interfering control
Sample PI control
Perform the following
Use the 2-position ON/OFF block (Block
Model 001).
Use the 3-position ON/OFF block (Block
Model 002).
Use the Analog/Pulse Width Converter
block (Block Model 192).
Use with the Basic/Advanced PID block and
Split Converter block (Block Model 169).
(Supported only by Loop Control Board ver-
sion 1.5)
Use the First-order Lag block (Block Model
141).
Use the Ratio Setting block (Block Model
033) or the Addition/Subtraction block
(mode 121).
Model 121)
Use the Square Root block (Block Model
131) (with low-end cutout function).
Use the Pulse Input Unit, and enter to the
Accumulator for accumulated value input
block (Block Model 184) for continuous
accumulation.
Use the Temperature and Pressure Correc-
tion block (Block Model 136).
Use the Constant Item Setting block (Block
Model 171).
Use the Constant Selector block (Block
Model 165) or the Constant Item Setting
block (Block Model 171).
Use the Constant Item Setting block (Block
Model 171).
Use the Bank Selector block (Block Model
168), and Basic PID block (Block Model
011), or Advanced PID block (Block Model
012). (Supported by LCB01/05 with version
1.5 or later and LCB03 only.)
Use the Ramp Program block (Block Model
155), the Segment Program block (Block
Model 156), the Segment Program 2 block
(Block Model 157), or the Segment Program
3 block (Block Model 158).
Use a serial connection for the Basic PID
block (Block Model 011) or Advanced PID
block (Block Model 012).
Use the Dead Time Compensation block
(Block Model 149) or the Advanced PID
block (Block Model 012).
Use the Advanced PID block (Block Model
012) or the Lead/Delay block (Block Model
147).
Use the ON/OFF Timer block (Block Model
206).
